Patent ID: 8737694

Claim:
A computer-implemented method for mapping relative changes in organic matter in an agricultural field, comprising: mapping relative changes in organic matter within soil in an agricultural field utilizing at least two individual bands from one or more remotely sensed images of the agricultural field using a processor unit, each of the two individual bands associated with a light spectrum wavelength range, wherein each of the at least two bands is weighted based on a contribution each band provides to predict the relative changes in organic matter; using the processor unit to separate the mapped relative changes in organic matter according to geographic zones, each zone defined by weighting pixels of the one or more remotely sensed images according to the predicted organic matter falling within a predefined range of change, and each zone comprising a different range of relative organic matter with respect to an adjacent zone, wherein zone boundaries are defined where a value of the weighted pixels reaches a predefined threshold; and using the processor unit to recommend a nutrient supplement for each zone based on the range of organic matter associated with each of the mapped zones; and storing the map of the zones of the agricultural field and the recommendation of the nutrient supplement for each zone in a memory unit.
