Agricultural liquid injection product application process and apparatus

摘要

Provided are a method of and apparatus for applying a chemical to an agricultural field. A current position of chemical application equipment used to apply the chemical to the field is determined. A desired application rate for a first position a distance d ahead of the current position of the chemical application equipment is determined or retrieved from a data base containing a plurality of chemical application rates for the injector channels. The chemical application equipment is controlled, while the chemical application equipment is approximately at the current position, to change the chemical application rate from a current application rate to the desired application rate if the desired application rate is within a predetermined range, and to maintain the current application rate if the desired application rate is outside of the predetermined range, and for accurately recording chemical application rate and position data.
