Weed Management, Tillage, and Crop Rotations in Dryland Farming Systems

Following the Dust Bowl of the 1930s, tillage implements were developed that preserved more plant residues on the soil surface, decreasing the potential for soil erosion. Beginning with the advent of triazine herbicides in the 1960s, mechanical tillage has been reduced and greater crop residue levels have been maintained, resulting in more environmentally and economically sustainable farming practices.
