Simultaneous heat and water model of a freezing snow-residue-soil system

, : Simultaneous heat and water model of a freezing snow-residue-soil system. Paper, American Society of Agricultural Engineers (87-2567): 29

A simultaneous heat and water (SHAW) model for predicting the effects of cultivation and residue management on soil freezing was developed and verified. It can be used to evaluate cultivation-residue management options for hydrologic and crop production purposes.
