Title: Water Use by Soybeans in Stubble and on Bare Soil
Author: Larsen, J.K.; Enz, J. W.; Brun, L.J.
Description: In 1985, farmers were interested in reducing costs and reduced tillage systems. They wanted to reduce soil erosion by maintaining soil residues. The timing of tilling, the type of equipment used and the amount of residue left behind in determining the conservation of soil moisture. The article discusses the various cycles of evaporation and varying factors affecting such. The purpose of the report reviewed was to show the effect of wheat stubble on water conservation as compared to a bare soil treatment. Soybeans over their growing season was used. The field methods, the over winter soil change, the springtime evaporation and the growing season water usage are given. The most significant benefit from snow trapping and subsequent soil water content. Stubble reduced stage one evaporation during rainy periods.
