"Soil blowing is often a serious problem from December to May [in the Southern Great Plains], when the soil is, in many cases, bare and winds are high. This period is often referred to as the 'blow season.' The whole art of preventing and controlling soil blowing consists in keeping nonblowing materials on the surface. These may be crops, crop residues, or clods. When crops are absent, the essential feature in preventing soil blowing is the use of implements that lift clods and other nonblowing materials to the surface rather than implements that pulverize or destroy them.... Since tillage is dependent on implements, it seems of first importance to consider the implements that may be used to discuss their merits and shortcomings in relation to soil blowing.... From the general principles stated and the specific examples of implement use given, most farmers can probably decide on the correct applications for their farms." -- p. 1-3
