1. A method for calibrating a system for treating plants growing in a geographical area, comprising the steps of:
- (a) passing an optical sensor over a part of the geographical area;
(b) measuring with the sensor a plant growth parameter at a plurality of locations within the geographical area; and
(c) analyzing the growth parameter measurements to generate a normalized response function for the geographical area.

Abstract
An algorithmic method is described for sensor-based real-time application of an agricultural material. Method includes means for characterizing and treating crop biomass variability without the use of a grower managed reference crop. Crop variability is determined statistically by driving one or more transects through the field in order to collect crop canopy information for sensor calibration purposes.

9. A method for applying a controlled amount of an agricultural product to a crop growing in a field, comprising the steps of:
-
(a) passing an optical sensor over a part of the field; (b) measuring with the sensor a crop growth parameter at a plurality of locations within the field; (c) analyzing the growth parameter measurements to generate a normalized response function for the field; (d) mounting an optical sensor on an applicator for the agricultural product for transport across the field to sense the crop growth parameter at a location in the field; and (e) applying the agricultural product on the crop at the location in the field in an amount that is adjusted in response to the crop growth parameter for the location as compared to the normalized response function.
