The wet 2008 fall put a hold on tillage operations for many farmers, which may provide them with time to consider the use of no-tillage system for soybean after corn. Conventional tillage, whether for corn or soybean, generally has shown limited advantage in yield and economic returns. The exception is a few cases with corn that involve lack of drainage and wet, cold soil conditions.
