Delayed and Prevented Planting Provisions PDF document
William Edwards, Iowa State Univ.
RLN's editorial note: This publication from Iowa State University outlines some of the key provisions of crop insurance policies relative to delayed or prevented planting. Exercise caution in your interpretation of the information contained therein because some of the details may be specific to Iowa policy-holders. Always consult directly with your own crop insurance representative about your specific crop insurance policy provisions.

Planting Delays and Switching to Soybeans: A New FAST Spreadsheet
Gary Schnitkey and Ryan Batts, Univ of Illinois
RLN's editorial note: This handy Excel spreadsheet offers some assistance in making an economic decision whether to switch from corn to soybean with delayed planting. However, recognize that your choice of yield, grain price, and production costs are critically important to whether the predicted economic results will be close to accurate. My advice: Do not simply use the spreadsheet's default values, but thoughtfully input your own values. Also, recognize you are limited to selecting geographic areas only within Illinois, so non-Illini farmers should exercise caution with the use of this tool.
