COMPUTER SPECIFIED FERTILIZER APPLICATION FOR AGRICULTURAL FIELDS

摘要

A map of site specified amount of soil nutrient (140) is applied in fertilizer to an agricultural field using a map of specified amount of the nutrient needed to produce the maxiumum yield (132). Subtracted from the amounts of needed nutrient from the current existing nutrient in the field (138) and thus producing the map of site specified nutrient amount to be added to the soil (142). The nutrients amounts are added by using the map and conventional variable rate fertilizer application methods. The amount of soil nutrient need to produce the maximum yield is created using site-specific map measures of biomass produced from a pass season created from a remotely sensed biomass image (120).
