Abstract
A system and method for providing a fertilizer recommendation for an agronomic field based on a direct measurement of a crop nutrient level at a measurement location, including receiving field and remote data. Optional approaches include adjusting the fertilizer recommendation based on at least one of the received field, farm and/or weather data. Alternatively, based on field data, at least one measurement region for carrying out a measurement for providing a fertilizer recommendation is determined. Optional approaches include receiving remote data, farm data and/or weather data to manage the improve the measurement region determination.

A method for providing a fertilizer recommendation for a crop with a handheld system comprising a crop nutrient detection device, wherein the method comprises steps of:
- i) determining a crop nutrient content by carrying out at least a measurement Mj by means of the crop nutrient detection device in at least one measurement location (xj, yj) within an agricultural field;
- ii) determining a crop nutrient detection device position at the at least one measurement location;
- iii) receiving data, wherein receiving the data comprises receiving field data of the agricultural field and receiving remote spectral data from at least a plurality of wavelengths of the agricultural field;
- iv) processing the data to obtain at least one coefficient indicative of a crop status within the agricultural field;
- v) generating the fertilizer recommendation for the crop within the agricultural field based on the determined crop nutrient content, the determined position of the crop nutrient detection device and the at least one coefficient indicative of the crop status within the agricultural field,
- wherein the fertilizer recommendation for a given location NREC(Xi, yi) based on a plurality of measurements M at locations (xj, yj) is defined by the following equation:

- wherein f represents an agronomic calibration function that translates an at least one measurement value of the crop nutrient detection device into a baseline value fertilizer recommendation;
- g represents an agronomic calibration function that translates a value R of the at least one generated coefficient at (xi, yi) into a respective location dependent fertilizer recommendation, R represents the value of the at least one coefficient or a combination thereof considered at position (xi, yi), and C and R0 represent calibration constants;
- and
- vi) transmitting the fertilizer recommendation to one or more agricultural machines used to perform one or more fertilizing operations within the agricultural field.
A computer implemented method for determining at least one measurement region for carrying out at least one measurement with a crop nutrient detection device for providing a fertilizer recommendation to a crop, comprising steps of:
- i) determining an agricultural field comprising the crop for which the recommendation is intended by receiving location data from a location unit of the crop nutrient detection device or a user input;
- ii) receiving data, wherein receiving the data comprises receiving field data of the agricultural field and receiving remote spectral data from at least a plurality of wavelengths of the agricultural field;
- iii) processing the data to obtain at least a coefficient indicative of a crop status within the agricultural field;
- iv) determining at least one measurement region within the agricultural field for carrying out the at least one measurement based on the data and the at least one coefficient;
- v) displaying, on a display unit, the at least one measurement region within the agricultural field for carrying out the at least one measurement based on the data;
- and
- vi) receiving the at least one measurement from the crop nutrient detection device within the at least one measurement region.
A system for determining at least one measurement region for carrying out at least one measurement with a crop nutrient detection device for providing a fertilizer recommendation to a crop, comprising:
- a display unit;
- an input unit;
- wherein the system comprises a processor configured to carry out a process comprising steps of:
- determining an agricultural field comprising the crop for which the recommendation is intended by receiving location data from a location unit of the crop nutrient detection device or a user input to the input unit;
- receiving data, wherein receiving the data comprises receiving field data of the agricultural field and receiving remote spectral data from at least a plurality of wavelengths of the agricultural field;
- processing the data to obtain at least a coefficient indicative of a crop status within the agricultural field;
- determining at least one measurement region within the agricultural field for carrying out the at least one measurement based on the data and the at least one coefficient;
- displaying, via the display unit, the at least one measurement region;
- and
- receiving the at least one measurement from the crop nutrient detection device within the at least one measurement region.
