ABSTRACT Arelatively simple residue decay equation was developed based on change in residue surface area with time. A weighted time variable was then developed to account for differences in residue type and variations in environmental conditions for different days. The equation was evaluated with data collected at Ames, IA; Kimberly, ID; and Columbia, MO. Residue decay for corn and wheat was evaluated at two locations and soybeans and sunflowers at one location. The lowest R2 obtained was 0.87 and the model was significant at the 99.9% probability level for all data sets tested.
