VARIABLE RATE CHEMICAL MANAGEMENT FOR AGRICULTURAL LANDSCAPES
First Claim
1. An apparatus for applying agrochemicals within a geographical area, the apparatus comprising:
- a dispensing system configured for dispensing the agrochemicals;
a variable rate controller operatively connected to the dispensing system and configured to control dispensement of agrochemicals from the dispensing system;
wherein the variable rate controller is programmed with an algorithm which uses a plant growth stage appropriate plug value for an initial calibration.

Abstract
An apparatus for applying agrochemicals within a geographical area includes a dispensing system configured for dispensing the agrochemicals and a variable rate controller operatively connected to the dispensing system and configured to control dispensement of agrochemicals from the dispensing system. The variable rate controller is programmed with an algorithm which uses a plant growth stage appropriate plug value for an initial calibration. A method for applying agrochemicals within a geographical area includes acquiring a growth stage appropriate plug value for an initial calibration, using the growth state appropriate plug value in the initial calibration, and applying agrochemicals to the geographical area according to the initial calibration.
