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;

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.
