The control of blowing soils
1910
Free, E. E. (Edward Elway) | Westgate, J. M.
"The effect of wind in blowing soils is in the aggregate of much importance in the humid sections, although the process is slower and less obvious than in the drier regions. The good effect of the shifting of soil lies in the mixing of the soil particles and the renewing of the surface layers. The evil effects occur principally in the arid and semiarid regions. The most practical means of control like int he proper adjustment of the cropping and tillage system so as to provide at the critical stages a protection of either plants or rough surface soil. Increasing the humus content of the soil also reduces the danger of blowing. when the land is used for intensive farming, brush lines, straw covering, hedges, or windbreaks of tree constitute the most efficient protection."--Page 23.
