Derivation of a Cropping System Transfer Function for Weed Management: Part 2 – Microwave Weed Management

Abstract

 System behaviour is described by transfer functions, which relate the system’s output to one or more input parameters. This paper derives the transfer function for crop yield potential as a function of applied microwave energy for control of weeds. The resulting transfer function reveals that microwave weed control and soil treatment can increase normalized crop yield potential above the ideal weed free potential. It also revealed that there was an ongoing yield advantage associated with a once off microwave soil treatment to deplete the weed seed bank.
