RECENTLY, Duley and Russel proposed for experimental consideration a new method of farming that they call "sub-surface tillage" (3, 4). By this method soil would rarely if ever be turned upside down, but would be handled as regards all operations of seedbed preparation, planting, and tillage, in such manner as to leave all residues so far as possible on the surface of the ground. This method has four objectives: namely, facilitated infiltration, reduced evaporation, decreased erosion by water, and improved control of the hazards of blowing. In another paper Duley (i) has dealt with experimental work being conducted by the Soil Conservation Service and the Nebraska Experiment Station on factors affecting infiltration. This paper will deal with the question of surface evaporation.
