Effects of wind erosion - fao

Stubble and crop residues in the soil cut wind-speed at ground level. • Soil moisture increases cohesion of sand and loam, temporarily preventing their erosion by wind. Wind erosion control. Wind erosion control is carried out on two fronts: reducing wind-speed at ground level, and increasing soil cohesion, thus improving soil resistance to wind.

Carbon dynamics of sodic and saline soils following gypsum ...

Effects of gypsum and organic material addition on soil properties The decrease in pH at all depths in the Tarcoola + G soils was due to the incorporation and dissolution of gypsum. Due to the high pH of the soil, most likely as a result of Na 2 CO 3, the addition of gypsum provides a source of Ca 2+ which precipitates as CaCO 3 and Ca(HCO 3 ) 2, resulting in a decrease in soil pH.
