Calculating Return On Investment for On Farm Trials

Cover image of Calculating ROI for On Farm Trials

An on farm trial tests the yield or economic effect of a management treatment on an agricultural system. This information can then form the basis for wider application of the treatment in other parts of the farm. Precision Agriculture (PA) tools offer a simple and effective means to implement and measure such trials as part of a normal farming operation. This booklet uses working examples of how PA tools have enabled growers to measure the economic returns of treatments to help them with whole farm decisions.

The data expressed in this booklet is site specific and does not necessarily represent the effectiveness of an agronomy treatment for your farm. The purpose is to provide a working example of the methodology to other growers so they may competently conduct their own on farm trials to calculate the potential return on an investment.
