Comparing the economics of certified organic production versus conventional farming can be a challenge. The department has created the rotation modeling spreadsheet to serve as a highly customizable tool for farmers considering organic production. The spreadsheet allows users to design and compare up to four organic rotations and four conventional rotations.
In view of the price volatility in recent times, two sets of spreadsheets (Excel format) are provided with default values to reflect the assumptions used in crop prices and input costs. The first set is based on mid-2007 commodity prices and input costs from 2007-2008. The second uses 2006 crop prices and costs. Default values entered into both sets of spreadsheets are for a "first glance" level of analysis only.
