摘要：
The present invention provides a Method for prescribing site-specific fertilizer application in agricultural fields. A map of site-specific amounts of a soil nutrient, to be applied in fertilizer to an agricultural field is created using a map of site-specific amounts of the soil nutrient needed to produce the maximum possible yield at the particular site. Subtracted from the site-specific amounts of nutrient needed are site-specific amounts of the nutrient currently existing in the field, thus producing the map of site-specific nutrient amounts to be added. The nutrient amounts may be added to the soil using the map and conventional variable-rate fertilizer application methods. In one embodiment, the amounts of the soil nutrient needed to produce the maximum possible yield at each site is created using a map of site-specific measures of biomass produced by the field in a past growing season or seasons, which in turn is created from a remotely sensed biomass image. Following invention is described in detail with the help of Figure 1 of sheet 1 which shows block diagram of a computer system containing in memory a computer program in accordance with the invention. Figure 2 of sheet 1 which shows graph illustrating a calculation used in the embodiment.
