Organic vs. Conventional

Modeling the Economics with Crop Rotations
 
Unload

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.

 

Important Notes:

  1. The effectiveness of spreadsheets as a comparison tool depends heavily on the assumptions. Users should select rotations and assumptions appropriate for their farm, risk tolerance, and perspective of future crop prices and input costs. Default rotations are provided as examples only, and may not be suitable for some farms.
  2. The Rotation Modeling spreadsheet is most appropriate for preliminary comparison of rotations or for evaluating individual fields. This analysis does not consider fixed costs. A whole-farm modeling spreadsheet (See link in left navigation) includes fixed costs, but is a bit more complicated and is provided only as an example.
