"But modern man's activities have greatly speeded up this process to the point where it is recognized as a serious environmental problem and a threat to our economic wellbeing through loss of our productive agricultural capacity.” he said.
“The rate at which soils erode depends upon soil type, steepness of slope, amount of runoff, and other things. But ironically, the solution to much cropland erosion can be relatively simple.” Walters said. “By leaving residues on the surface, evaporation, runoff and erosion are reduced. We call this ‘conservation tillage.' ”
