[METHOD AND SYSTEM FOR SPATIALLY VARIABLE RATE APPLICATION OF AGRICULTURAL CHEMICALS BASED ON REMOTELY SENSED VEGETATION DATA]
First Claim
1. A method for generating a prescription for controlling the application of agricultural inputs to an area of cultivated grass, comprising:
- (a) processing remotely sensed digital image data, in the absence of a pretreated reference portion of the area of cultivated grass to characterize spatial variation of currently existing growth vigor of said cultivated grass; and
(b) generating a prescription for applying said agricultural inputs to said cultivated grass at a spatially variable rate within said area, as a function of said currently existing growth vigor of said cultivated grass.

Abstract
Remotely sensed spectral image data are used to develop a Vegetation Index file which represents spatial variations of actual crop vigor throughout an area that is under cultivation. The latter information is processed to place it in a format that can be used by personnel to correlate and calibrate it with actually observed crop conditions existing at control points within the area. Based on the results, personnel formulate a prescription request, which is forwarded to a central processing site, where the prescription is prepared. The latter is returned to a mobile application means that directly applies inputs to the field at a spatially variable rate.
