The Effects of Gypsum on Agricultural Soils

Category:

The effects of gypsum on agricultural soils can be divided into three classes:

  • Its effects on soil physical characteristics
  • Its effects as a fertilizer on plant nutrition
  • Its effects as a soil amendment on problematic soils (sodic, acidic, clay soils)

In agricultural practices, the main objective in managing soil and the water and air inside it is to allow plant roots to achieve their full genetic potential so that they absorb as much water and nutrients that they can. Under these conditions, plants can realize their maximum yield per hectare. Consequently, suitable soil physical characteristics are one of the most important factors in maximizing yield. If soil physical characteristics are not appropriate for root growth, use of fertilizers and liquid nutrients will have very little effect on crop yield . Unfortunately, farmers usually ignore this and try to increase yield only by applying fertilizers and chemical solutions to soil whereas a small change in soil physical characteristics will increase efficiency of chemical fertilizers. Gypsum is one of the important soil amendments that substantially increases crop yield in agricultural lands by improving soil physical characteristics.
