Patent Description:
The general background of this invention is agricultural management. Increasingly sophisticated agricultural management systems are being provided to large scale agricultural enterprises, who operate sophisticated, sometimes automated, machinery within an integrated agricultural management system. However, a significant proportion of the food the world requires is produced by smallholders, who may have only one very small field, or a number of small fields, and who operate no, or little, mechanized machinery and for whom such sophisticated agricultural management systems are not appropriate.

For example <CIT> discloses a method for automatically mapping agricultural resources via mobile devices which has several components, the first one of them being the determination of the boundary based GPS coordinates for determining the location information. Additional information is collected in that so called mapping process and an agricultural development plan is generated for that specific area. However the additional information collected is not used to improve location accuracy.

It would be advantageous to provide agricultural management tools to aid such smallholders. It should be noted that the following described aspects and examples of the invention apply also for the device for agricultural management, the method for agricultural management, and for the computer program element and the computer readable medium.

According to a first aspect, there is provided a device for agricultural management, comprising:.

The input unit is configured to provide the processing unit with agricultural data. The processing unit is configured to determine at least one geographical location of an agricultural land area. The determination comprises utilisation of the GPS unit. The processing unit is configured also to determine agricultural management data, and the determination comprises utilisation of the at least one geographical location and the agricultural data. The output unit is configured to output agricultural management information to a user of the device on the basis of the agricultural management data.

In this way, a farmer who may not necessarily know exactly where his farm or a field in that farm is located, is able to be provided with agricultural advice that is tailored to his location. In other words, a device such as a smartphone can use its GPS unit to determine a location of the smartphone. From that location, agricultural advice and/or information can be provided to the farmer via the screen of the smartphone.

In an example, determination of the at least one geographical location of the agricultural land area comprises at least one movement of the GPS unit. In this manner, a farmer can move a device in order to determine the location of his field.

In an example, the at least one movement comprises the device being moved around at least one boundary of the agricultural land area. In other words, the farmer can delineate a field through positioning the device at a boundary of the field. In an example, the at least one movement comprises the device being moved around all of the boundaries of the agricultural land area. In this manner, a farmer can walk or otherwise move around the border of his field. Therefore, not only can agricultural advice/information be provided to the farmer that accounts for his location the advice/information can account for the size of the field.

In an example, the device comprises a camera. The camera is configured to acquire at least one image of at least one part of the agricultural land area, The determination of the at least one geographical location of the agricultural land area can then comprise utilisation of the at least one image.

Thus acquired imagery can be used to augment GPS provided data. In this way, the geographical location can be better determined through for example processing of landmarks in the imagery. In an example, the at least one image comprises at least one image of at least boundary of the agricultural land area.

In other words, imagery of a boundary can be used to better locate a field, including determining its boundaries. This can involve utilisation of satellite imagery. In an example, the at least one image comprises images of all of the boundaries of the agricultural land area.

In other words, a farmer can walk or otherwise move around the borders of his field, and image processing can augment the GPS data to better determine not only the location of the field but its boundary. Thus, the spatial size of imagery can be used to determine the size of features at the field boundary from which the extent of the boundary can be determined. In an example, the device has an inertial sensor configured to measure movement, and this information is used with the imagery to determine the outer boundary of the field and augment the GPS data to determine that boundary.

Utilisation of imagery to augment GPS derived data can be especially important for very small fields that may only be <NUM> wide or <NUM> wide, and where absolute GPS errors could lead to significant errors in the determined field boundary.

In an example, the device comprises a transmitter. The processing unit is configured to utilize the transmitter to transmit information comprising the at least one geographical location of the agricultural land area. The device also comprises a receiver. The agricultural data can then comprise specific agricultural data relating to the agricultural land area that has been received by the receiver.

In this manner, the geographical information, such as the absolute location of the field and its boundary can be sent to a remote server for example. Then specific agricultural advice can be sent to the farmer for that location. In an example, the transmitted information comprises information input by the user. In other words the specific agricultural advice provided to the user, for that geographical location that can include the exact boundary of the field can take into account information such as the crop being grown by the user, when it was sown, the agricultural treatments such as herbicides and insecticides used by the farmer, how and when, when the field was watered, information on pests and diseases can also be acquired by the farmer that could be in written or image form and all or some of this information transmitted in order that the farmer receives bespoke agricultural advice that relates to what he or she is doing.

In an example, the agricultural data comprises information input by the user.

<FIG> shows an example of how a user uses the device. The user has an App on their smart phone. When asked to define where their field is to be found, the user is actually not sure. She lives in a rural community, has a very small field, and grows different seasonal crops that she sells at a local market. She grows her crops using the knowledge she has gained from successes and failures, and from knowledge gained from her neighbours. She however believes that she can do better, and is operating a device as described herein, that in this example is the smartphone operating an APP (application). Returning to her problem, as to where her field is to be located, the device requests that she walk around the boundary of her field. The device also asks that on her route around the field boundary she can take images of the boundary, but that this is not necessary. Having done this, she indicates that she has finished.

At this point, the mobile phone accesses a remote server via normal telecommunication transmissions, and information is downloaded to the smart phone. This information indicates what crops would be best to grow in that field. Knowing the size of the field, the farmer is provided with information regarding how much seed for example is required. Thus the remote server, from the general location of the user can provide information regarding the type of crop that could be grown and the seed sowing rate per unit area. A processor in the smartphone, from knowledge regarding the size of the field can then provide the farmer with information regarding the actual amount of seed required for her field. The farmer however can indicate the specific crop that she is growing, and can provide information via a keyboard and or take images regarding other information such as images of weeds, diseases and pests, and images of the crop itself. This information is again transmitted to the remote server, and the information provided back to the farmer indicates information such as what herbicides or pesticides/insecticides to use and how and when to use them as well as the quantities required. The information also specifies when to water the crop and when to harvest it.

Rather than use a remote server, if the smartphone has sufficient memory the database of information held on the remote server and the processing that is done to locate the field, and determine weeds/pests etc resides on the smartphone itself. In this case, information need not be sent to the remote server, but the farmer can be provided with the agricultural information even in remote locations with no telephonic coverage.

This exemplary embodiment of the invention covers both, a computer program that right from the beginning uses the invention and computer program that by means of an update turns an existing program into a program that uses invention.
