Crop weather indicators for 2005

The 2004 crop weather proved to be a record setter. A like weather pattern occurs about once every 10 years. It may not be the “best” strategy to assume that next year will be the same and that the best crop varieties during the 2004 season will be the best in 2005. Then again, do not fully rule it out; there is a 1-in-10 chance it will happen again.

Weather conditions are seldom such that highly reliable forecasts are feasible. Leading weather indicators, however, have proven useful in the anticipation of above or below trend crop yields during the past decade. Indicator models are usually reliable to ± 5 percent of actual yield.
