Precision Agriculture Yield Variability Analyzer
Will precision technologies pay on my farm?
When asking the question “Will precision technologies pay on my farm?”, one of the first things to consider is the level of within-field yield variability present – if the field conditions are uniform there is no benefit from variable rate management. In order to estimate the level of yield variability needed to signal an economic benefit, a simple decision aid was developed. The decision aid requires a minimal amount of input information:
High and low yields within a given field in pounds per acre;
- Production costs in $ per acre;
- Lint price in $ per pound; and
- Size of the field being considered in acres (or results can be reported on a per acre basis).
To make an estimate of potential savings from precision farming, the current analysis assumes areas of the field that are not profitable are removed from production. A discussion of the assumptions is presented in a later section of this user guide. This is a “beta” version of the decision aid; therefore, it should be one of many tools used in considering the adoption of precision technologies.
This decision aid requires Microsoft Excel version 5.0 or later (includes Office 97, 2000 and 2003); or Microsoft Office 2004 for Mac.
