Abstract
A method and system for managing nitrogen applied by nitrogen application equipment to a geographic region includes determining a growth stage for the geographic region using a crop module, and determining a nitrogen change for the geographic region based on the growth stage using a nitrogen change module, which can additionally or alternatively include determining an amount of nitrogen initially available for a geographic region.
Claims15
A method for managing nitrogen within a geographic region, the method comprising:
- a) receiving a first image of the geographic region from an imaging system, the first image associated with a first time;
- b) determining a first growth stage at the first time for plants within the geographic region based on the first image using a first crop system;
- c) determining a first nitrogen change for the geographic region based on the first growth stage using a nitrogen change system;
- d) estimating a first nitrogen availability for the geographic region at the first time based on the first nitrogen change;
- e) repeating b) to d) for a second nitrogen availability for the geographic region at a second time based on a second nitrogen change and the first nitrogen availability;
- f) receiving a second image of the geographic region;
- g) determining a reflectance for the second image;
- h) identifying a nitrogen status anomaly for the geographic region based on the second nitrogen availability and the reflectance;
- i) in response to identifying the nitrogen status anomaly, determining a nitrogen prescription for the geographic region based on the second nitrogen availability using a nitrogen prescription system;
- j) generating first control instructions based on the nitrogen prescription, wherein nitrogen application equipment applies nitrogen according to the first control instructions;
- k) determining a reference yield map for the geographic region, based on a set of historic images corresponding to historic instances of a recurrent time;
- l) determining a second crop system based on the reference yield map and an output of the first crop system for the recurrent time;
- and
- m) generating second control instructions based on a third nitrogen availability, comprising:
- repeating b) to d) using the second crop system and repeating i) to j).

- d) receiving a rainfall parameter for the geographic region, the rainfall parameter associated with the first time;
- and
- e) in response to the rainfall parameter exceeding a historic rainfall parameter, evaluating nitrogen status for the geographic region based on the rainfall parameter and a reflectance for the first image;
- f) in response to the nitrogen status indicating a nitrogen stress, determining a nitrogen prescription for the geographic region based on the nitrogen change using a nitrogen prescription system;
- g) generating first control instructions based on the nitrogen prescription, wherein nitrogen application equipment facilitates nitrogen application according to the first control instructions.
