A message is transmitted by the computing unit to the user to indicate composition and quantity. The selected manipulation and date of the manipulation are transmitted by the user at the computing unit and stored in the database.

Description

1 DESCRIPTION

The invention relates to a method of agricultural traceability, consisting in carrying out the following steps: a. Referencing the parcel and its area and preferably its geographic coordinates; b. Determination of the culture type vs. Establishment of a treatment plan for the said parcel, in particular the quantity of seed to be sown and / or the qualitative and quantitative determination of the products to be applied, in particular plant protection products, mineral products or organic products, with recommended planting date and / or or realized and / or date of application recommended and / or carried out and / or date of harvest recommended and / or carried out.

15 For reasons of food safety, the legislation in force, in particular Article 18 of the EEC Traceability Regulation 178/2002, which entered into force on 1 January 2005, requires the traceability of foodstuffs, animal feed and food producing animals. foodstuffs and any other substance intended to be incorporated or capable of being incorporated into food or feed, 20 at all stages of production, processing and distribution. Food business operators must be able to identify any person who has supplied a foodstuff and to identify the companies to which their products have been supplied. To this end, these operators must have systems and procedures in place to make the information in question available to the competent authorities at the request of the competent authorities. The obligation for the farmer to write everything dates from January 2006.

In particular, the farmer must be able to provide a list of phytosanitary products and mineral or organic fertilizers that he has applied to a plot during the crop year, specifying the date and the quantity applied. It must be possible to go back for several years. However, some of these products are incompatible with each other or are not authorized for certain crops or are authorized for several crops, but with different doses depending on the crop and the season of application. In any case, it is forbidden to exceed the approved dose. Others should not be applied for a certain period of time before harvest. For still others, it is forbidden to enter the parcel for a certain number of hours, or even day after application. In some cases, untreated areas should be respected on the edges of the plots. Wind speed must also be taken into account during application in order to avoid the risk of drift to a water point or neighboring crop that is sensitive to the product in question. The limit is set at 3 degrees Beaufort, about 12 to 19 km / h.

In addition to these general limitations, there are also local restrictions and seasonal restrictions. For example, it is forbidden to spread slurry in Moselle from November 1 to January 15 on a winter crop (rapeseed, winter wheat, etc.) and from July 1 to January 15 for a spring crop ( spring barley) or from July 1 to March 15 for corn. For the department of Meurthe-et-Moselle, spreading is prohibited from July 1 to January 15 for spring crops and corn. The ban dates for a winter crop are the same for all of Lorraine. However, nothing prevents these dates from changing from one year to the next.

Under these conditions, it becomes very difficult for a farmer to establish a treatment plan that strictly adheres to the regulations in force for his different parcels according to his different crops.

It is therefore common for the treatment plan to be drawn up by technicians from the sellers of plant protection products and fertilizers. This plan is established at the beginning or during the campaign and the purchase orders are established. However, it is possible that the farmer uses competing products instead of or in addition to products already discussed with the technician. Under these conditions, compliance with the regulations is no longer ensured.

In addition, it is possible that for external reasons, for example meteorological, the initial plan is not respected and the application of certain products is advanced or postponed. This is a new source of possible errors.

The object of the invention is therefore to propose a method which ensures the safest possible traceability, which makes it possible to comply with the legislation in force, even if it changes during the campaign, and which simplifies and secures the work of the customer. 'farmer.

This objective is achieved by the method according to the preamble in which the following steps are added: The parcel reference and the parcel processing plan are stored in a database of a computing unit; e. When performing one of the steps of the treatment plan, the reference of the parcel to be processed is transmitted to the computing unit that identifies it; f. According to the date of the day or the date of intended manipulation and the data stored in the database concerning the progress of the treatment program associated with the parcel identified, a message is transmitted by the calculation unit. to the user to indicate the possible manipulations; boy Wut. The user selects one of the manipulations proposed in step f and this selection is transmitted to the calculation unit; h. A message is transmitted by the computing unit to the user indicating the composition and the dose of seed and / or products to be applied according to the manipulation selected in step g; i. The manipulation selected in step g and the date of its actual production are transmitted by the user to the computing unit and are stored in the database.

With this method, the user can perform only authorized manipulation. It is sufficient for the user to contact the computing unit by indicating the date of the day or the date planned for the manipulation so that he can safely choose an authorized manipulation on the chosen date. In addition, once performed, the manipulation is stored in the database and it is therefore possible to follow at any time the treatment plan already made. In practice, this database can be housed on a centralized server where it is updated by each farmer. It can also be partially downloaded locally to a personal computer or handheld before being sent back to the central server for synchronization. In a third version, the database is stored exclusively on the farmer's PC or pocket computer. Since it is common for a farmer to have multiple plots with several types of crops, this one is not likely to confuse the treatment plan of one plot with that of another.

In order to better take into account the restrictions of use, it is preferable to associate a risk phrase with each product to be applied for which the use is regulated, and to memorize this information in the database of the unit of calculation, this information is preferably updated regularly by the administrator of the computing unit. The risk phrases and, where appropriate, the geographical position of the plot and / or the type of crop are preferably taken into account during the preparation of the treatment plan and / or during the transmission of the message of step h .

A message of incompatibility can be transmitted by the computing unit to the user if the latter attempts at a certain date to perform a manipulation incompatible with one or more of the manipulations carried out previously and / or with one or more future manipulations. Among the incompatibilities mentioned here, there are those due to the return period (DDR), those due to the pre-harvest time (DAR). The RFI indicates the delay between the application and the time when it is again possible to enter the parcel. This deadline aims to protect the health of the people having access to these parcels. The DAR indicates the number of days to be observed between the treatment and the harvest. This allows not to exceed the maximum allowable residue limit for a particular product associated with a particular crop. Thus, if a farmer wants to enter the parcel while the re-entry period (DDR) is not completed following the application of a product shortly before, the computing unit informs him so that he is patient until the end of this period. This message can also be sent if the farmer who applied a product is about to harvest when the pre-harvest time of the applied product is not completed.

Conversely, if the farmer wants to apply a product while the expected date of harvest is in the DAR, he will receive a warning warning him.

To remind the farmer of the restrictions that are associated with an application, including DAR, DDR and mixing restrictions, or exceeding a registered dose, the use of sulfonylureas, prohibition dates Spreading or exceeding the SPE (Surface Potential Spreadable: surface on which we bring organic matter) in case of input of organic matter, it is preferable that a message is transmitted by the computing unit to the user before, during and / or after handling.

3o To simplify the identification of the parcel, it is preferable that this identification be carried out using a GPS (Global Positioning System) module present on the user during the manipulation, said module being preferably integrated with a handheld computer. Thus, if the farmer is equipped with a handheld computer equipped with a GPS module, the parcel can be recognized directly in step e and the running program can be directly presented on the screen.

In order to allow the farmer or the technician during his visit for the implementation of the treatment plan to place a first order, it is planned following the establishment of the treatment plan of step c a step c 'during which the user's seed stock and / or products to be applied fixed in step c is determined and the complement to the needs for the campaign and / or the storage capacity of the user of at least some of these products and / or seeds are calculated, a purchase order being preferably edited and transmitted to the central unit. The technician can for example at the time of the visit make an exact recommendation with the commercial name of the product and order directly with his handheld.

In order to facilitate control, it is preferable to store the seed stock and / or products to be applied in the calculation unit and then in the database. In order to automate the management of the stock, the quantity of product left from stock is stored in the database after each manipulation and the value of the stock is adjusted. To facilitate the ordering of new products, a message may be transmitted by the computing unit to the user when the stock of one of the products to be applied or the seed stock has fallen below a predefined alert level. . The computing unit can then prepare a new order based on the treatment plan and transmit it to the user who if desired can validate it and order.

In order to take into account the seasonal constraints, it is planned to adjust the quantity of products to be applied indicated in the message of step h compared to the initial treatment plan according to the effective date of application and the legislation in force. force.

For each regulated product application, the computing unit determines, after step g, according to the geographic coordinates of the parcel, the untreated zone (ZNT) to be respected and transmits to the user a message indicating this zone ( NTZ). ZNT is different from one product to another. In practice, any watercourse identified on an IGN map at 1 / 25,000 scale should be lined with a grass strip of 5 meters. Currently, and subject to changes in legislation, if this device is put in place and the farmer records everything he applies and his sprayer is well equipped, the farmer is not required to follow the regulations concerning ZNTs. If this is not the case, the ZNT surface will be deducted from the total area of the parcel. It is preferable that the information necessary for traceability, such as the reference of the parcel and / or the treatment plan and / or the actual progress of the treatment and / or the stock and / or the state stored in a central computer and that the user can download, for example via the Internet, this information on his personal computer and / or on his handheld, and that information about the procedure carried out are transmitted from the personal computer and / or handheld computer from the user to the central computer that enters this information into the database.

In a preferred version of the process, a traceability report and a fertilizer report are drawn up at the end of the campaign.

An exemplary embodiment is presented below, in particular using the flowcharts presented in the following figures.

Figure 1: A method of entering an application with dose control; Figure 2: An input method for a phytosanitary intervention with control of the mixture; Figure 3: A capture method for a phytosanitary type intervention with DAR and DDR control. Figure 4: A capture and control process for organic fertilization;

At the beginning, the technician defines with the farmer his needs. It lists all the parcels with their geographical coordinates and their areas PAC (Common Agricultural Policy = reference surface). The same island can be divided into several plots if different crops are planned. For this, the farmer prepares each parcel with a GPS module and the data thus obtained are recorded. Each parcel is associated with a surface and a culture. This information is also stored in the database. 30 For each plot, the technician defines with the farmer a treatment plan that indicates the recommended date of sowing and harvesting, as well as the recommended dates for applications of plant protection products and organic and mineral fertilizers. The recommended application date will be effective depending on the theoretical date of harvest.

To establish this plan, the technician uses a database containing regulatory restrictions and cross-tabulations. These regulatory restrictions are of several types: • The deadlines to be respected after an application before being able to re-enter the field (DDR = Re-entry Date), or before being able to harvest after an application (DAR = Date Before Harvest); • Sowing and harvest dates based on the geographic location of the plot; • Risk phrases associated with each product. These are indications on the labels of chemicals, which indicate the risks involved in their use, contact, ingestion, inhalation, handling or release into the wild or in the environment. environment. In particular, the T or T + classification (toxic products) associated with risk phrases R40 (suspected carcinogenic effect, possible risk of irreversible effects), R68 (possibility of irreversible effects), R48 (risk of serious effects on health) in case of prolonged exposure), R62 (possible risk of impaired fertility), R63 (possible risk during pregnancy of adverse effects for the child) and R64 (possible risk for babies fed breast milk). It is forbidden to mix products T and T +. Similarly, it is forbidden to mix R40 and / or R68 products with each other, R48 products with each other or R62 and / or R63 and / or R64 products with each other. Other combinations are in principle permitted unless the regulations change; • The dates of application allowed for certain products depending on the geographical location of the parcel; • Vulnerable areas and areas with limited inputs; • Approved doses; • dates of prohibition of spreading; • The sulfonylurea products.

The plan thus established is stored in the database. In order to facilitate the first order, the farmer's stocks of seeds and products to be applied, fixed in the treatment plan, are determined. The storage capacities of the farmer are evaluated and the total quantity of products and seeds needed for the campaign is calculated. Based on these results, the technician or farmer establishes a first order that is transferred directly to the computing unit. This command is stored in the database.

It is preferable that all the information be centralized on a central server managed for example by the supplier of the products to be applied. This server can be hosted on the Internet. The database is for example a database known as MySQL. The technician and later the farmer can connect to the central server with their PCs, laptops or handhelds via the Internet. Thus, the information entered is directly recorded in the database.

The farmer has a PC and / or laptop. He can prepare the farm for the manipulation he envisions. Depending on whether the program is installed locally on its PC or installed externally, for example on a central server, the farmer launches his application or connects to the computing unit and tells him the expected date of the handling and reference of the plot. The calculation unit then proposes one or more possible applications depending on the season and the state of progress of the established plan, in particular according to the applications already carried out.

These different applications are proposed on the screen, for example in the form of a drop-down menu. The farmer enters the desired application and transmits the information to the computing unit. In response, the computing unit transmits to the farmer, according to the data stored in the database, the composition and quantity of the product to be applied. It also indicates the untreated areas (ZNT) to be respected and, if applicable, the precautions to be observed following application, particularly in terms of risk phrases, DDR and DAR, exceeding approved doses or products already applied. If it is the harvest and the DAR is respected, the computer does not indicate anything, and the farmer simply has to validate the information. The farmer can then prepare the products he needs. It goes without saying that the farmer can prepare his products directly by consulting the pre-established plan.

In a preferred embodiment, the farmer is equipped with a laptop equipped with a GPS module and a 3G type of Internet access. Once in the field, it connects to the central server and the laptop transmits directly to the latter the geographic coordinates of the parcel that have been determined by the GPS module. The central server thus directly identifies the parcel and proposes the various possible applications according to the date of the day. The farmer selects the desired application and the handheld stores and transmits this information to the central server.

All data can be stored on the farmer's handheld or PC. In response, it transmits a message indicating the composition and the dose of product to be applied. The farmer confirms that he is preparing to apply this composition with this dose. This information is transmitted to the central server which stores them as being made.

If the farmer does not have a pocket computer equipped with a GPS module and a 3G Internet access, he can, once the manipulation is done, connect using his PC to the server. Similarly, if he does not receive 3G in the field, he can connect his handheld to his PC and transfer over the Internet the stored data that he should have transferred on site via 3G. As before, the server will propose according to the date indicated, the possible manipulations and the farmer will choose the one that he realized. As before, the server will tell him the composition and quantity of products he is supposed to have applied. It is no longer up to the farmer to confirm that he has done this well. In principle, the farmer can add applications, modify the pre-established plan or apply another composition or dose other than the one initially planned, provided that the regulations are respected. In this case, it must introduce these changes into the database so that they can be taken into account in subsequent applications. On the other hand, if the regulation is not respected, for example because the dose proposed by the farmer is higher than the homologated dose, the calculation unit will send him an alert which could be blocking.

It is also possible to monitor the status of the stock. This also allows a control of the applied doses. Indeed, if the stock is lower than the calculated one, it means that the doses really applied were higher than the doses seized in the application. Current legislation limits the quantity of products stored according to the storage capacity available to the farmer. It is therefore generally necessary to make several orders per year to cover all the needs of a campaign. When the farmer enters the data bank that he has applied to a certain plot of land in such quantity, it is possible, if the initial stock status has been stored in the database, to follow from day to day the evolution of the stock of each product. As soon as the level of a product falls below a pre-established limit level, a message can be sent by the server to the farmer to inform him. A purchase order, taking into account the progress of the campaign and the legislation in force, can be prepared. There is no longer the farmer to validate it and transmit it to the server. The latter can in turn pass it on to the supplier of phytosanitary products to prepare and deliver the order.

Thanks to this monitoring of the stock, it is also possible, during a control, to make sure that the theoretical stock corresponds to the real stock.

Alerts may be provided to inform the farmer that he is about to perform improper handling and, if necessary, block the process. Applying a product that would normally end after the expected date of harvest is an example of a non-blocking alert. The farmer is simply informed that if he applies the product planned on the date indicated, it repels the beginning of the harvest by the date originally planned. On the other hand, if the farmer wants to harvest before the DAR is completed, the computing unit will transmit a blocking alert, for example impossible to harvest, DAR not respected.

On the other hand, if the farmer is about to make a prohibited mixture because of incompatible risk phrases (a mixture of two R40 phrase products), or to apply a higher dose than allowed in the geographical area at the date indicated , or if he tries to enter the plot before the end of the re-entry deadline (DDR), the server informs the farmer and blocks the process.

In addition, the method provides a procedure with which the farmer can introduce manipulations that were not initially planned. The farmer must be able to enter into the database of products that he has for example bought from another supplier. He then enters the name of the product or products he is about to apply, the quantity to apply, their risk phrases, their DDR and DAR, areas of non-treatment, etc. If alert procedures are provided, the process will check that the composition to be applied respects from the point of view of its composition the prohibition due to the risk phrases, as well as the DAR and DDR and that the quantity that will be applied does not exceed the limits allowed in this geographical area at this time of the year.35 At the end of the season, the database has all the information necessary to establish the agricultural traceability report and the manure report. If the regulations evolve during the season, it is possible to make a nitrogen, phosphorus and potassium balance.

The fact that this data can be stored on a non-manipulable server by the farmer is an additional guarantee of security. In this case, a farmer who is not respectful of the legislation is not able to correct the data stored in the database hosted outside his site. However, it is conceivable to provide the possibility for the farmer to modify the stored data to correct an input error on his part.

In concrete terms, the central server contains the application as well as the database. This server is hosted on the internet. The web application is developed in PHP technology (Hypertext Preprocessor = hypertext preprocessor). The database is a database known as MySQL. It contains all the data entered by the phytosanitary supplier's staff as well as all the seizures made by the farmers on the pocket computers and / or the PC computers.

The provider's staff connects to the application via the Internet. Farmers who own a computer can also connect to the application. The information entered is directly recorded in the database.

Farmers use every day a fully autonomous pocket computer.

The information entered on this handheld is stored locally in files: "export_gps.xml" for GPS geolocation entries, "export_prepsol.xml" for soil preparations, "export_feo.xml" for organic fertilizers, "export_tps .xml "for phytosanitary treatments," export_fem.xml "for mineral fertilizers and" export_cul.xml "for sowing and harvesting. The entries are based on the setting made on the application (setting products, setting parcels, etc. ...), this setting is stored in the "import.xml" file. A synchronization process is used to update this file and to save the entries made on the handheld to the central server.

The different stages of synchronization are as follows: - connection of the handheld on the Internet via 3G or the PC via the Internet; - connect the handheld to the application; - sending the contents of the files "export_xxx.xml"; processing of these files on the central server, which consists in recording in database the data entered by the farmer; creation on the server of the contents of the "import.xml" file; sending this content to the handheld; ù creating the "import.xml" file on the handheld; ù delete the "export_xxx.xml" files on the handheld.

The method notably provides the following steps:

1. The administrators or the staff of the supplier enter on the central server 15 farmers and their characteristics thus giving access to the farmers concerned; 2 The administrators or the supplier's staff seize the delivered products to the farmers; Farmers retrieve this information by synchronizing their pocket computer with the central server; 4 Farmers at the time of their intervention enter the intervention on their handheld (if they are in their field) or on the central server if they are at home; If necessary, farmers synchronize the information entered on the handheld with the central server; 6 When the time comes, the administrators or the staff of the supplier generate the follow-up documents (trace sheet or follow-up, manure report).

Figure 1 shows a flow chart of the process when selecting a product, with dose control. The farmer connects and identifies the plot. This identification is done manually if it is at home, or by GPS if it is in its field and it is equipped with a GPS module. Depending on the date, the farmer chooses from a menu one of the possible interventions. The date can be entered automatically if the computing unit recognizes via the information provided by the GPS that the handheld is in the parcel. It can also be entered manually if the farmer is entering from his PC. In this case, he chooses a phytosanitary intervention. The calculation unit recognizes the type of crop according to the parcel identified and proposes a list of possible types of products at the date considered. The farmer selects a type of product (herbicide, fungicide, insecticide, etc.) from this list. It then appears a list of the corresponding products among which the farmer chooses the one he wants to apply. The computation unit extracts from the database the dose recommended in the treatment plan or by the manufacturer and extracts from the database the dose per hectare or calculates it. A message informs the farmer of this dose. After the application, either the farmer validates the dose or he enters the dose actually applied if he has changed the recommended dose in the treatment plan. The calculation unit compares the calculated dose with the actual dose applied. If the applied dose does not exceed the approved dose, then the entry is validated and the manipulation is recorded in the database. A report is published. If, on the other hand, the applied dose is higher than the homologated dose, then the calculation unit alerts the farmer.

Figure 2 shows a flowchart for controlling a mixture. The initial part is identical to that of the flowchart of Figure 1, but in this example, it is not the dose, but the risk phrases that are controlled. For this, once the product is entered, the calculation unit extracts from the database the risk phrases corresponding to the product. The computing unit performs a test to ensure that the products to be applied are compatible with each other. If this test is favorable, the farmer can validate the input, the data is saved and a report is edited. If, on the other hand, this test detects an incompatibility, the computing unit alerts the farmer.

Figure 3 shows a flowchart to monitor compliance with the DAR and DDR. Once the parcel has been identified, as well as the type of crop, the type of intervention, the product to be applied and the date of application, the calculation unit extracts from the databank the DAR corresponding to the selected product. It also extracts the expected harvest date for this crop. It then performs a test to check that the time remaining before harvest is greater than the DAR associated with the product to be applied. If this is not the case, the computing unit alerts the farmer. If it does not, it searches for the last product applied and the date it was applied and extracts the corresponding DDR from the database. The calculation unit performs a test to check that the elapsed time since the last intervention is much higher than the DDR of the last product applied. If it does not, it alerts the farmer. If not, the entry is validated and the information is saved. A report is published.

The last flowchart presents a control method when spreading an organic fertilizer product (slurry for example). After logging in and having identified the plot, the farmer chooses from the menu the organic fertilization type intervention. It indicates the crop, the product it wants to spread and the date of application. The computation unit searches for the department corresponding to the identified parcel, extracts from the database the blackout dates corresponding to the product to be spread according to the crop concerned. It performs a test to check that the intended application date is not in a blackout period. If the test is favorable, the entry is validated, the data saved and an edited report. Otherwise, the computing unit alerts the farmer.

It goes without saying that the various control methods shown in the figures are not necessarily independent, in particular those of the first three figures. On the contrary, they can follow each other and constitute a continuous chain of control.

According to the invention, it is also provided when the process is managed by a supplier of seeds and / or plant protection products, to manage the stock of the different products of the latter according to the orders placed by the customers and stored in the bank of data. An alarm is sent to the supplier when his stocks are below a predefined threshold value.
