Gypsum, the soil conditioner

Correcting materials used for soils with high magnesium or sodium can basically be divided into two main groups. The first group –e. g. gypsum- add “calcium” ions to soil solution directly, and the second group –e. g. various acids or sulfur- reduces soil acidity which results in lime dissolution in soil and release of its calcium ion. Using gypsum corrects some other chemical, physical, and even biological characteristics of the soil. So the consumption of gypsum must be prioritized. And is expected to result in significant growth increase and yield in areas it’s deemed necessary according to respective tests.

Besides, gypsum is also effective in improving unfavorable conditions resulting from boron toxicity. Leaching with ample water is among the correction methods of soil remediation in the soils suffering from toxic boron levels. Using gypsum for leaching can help reduce water required for leaching up to one-third of required amount in some cases. that these situations usually occur in areas with the water limitations.

Using gypsum for leaching

Using gypsum for leaching can help to reduce the amount of water required for leaching. which can make this method more feasible in water-limited areas. Gypsum can help to improve soil structure. which can increase water infiltration and reduce the amount of water needed for leaching. In addition, gypsum can help to displace sodium ions in the soil. which can reduce the adsorption of boron and make it more available for leaching.

Gypsum has some or all of the following advantages directly or indirectly:

Sodium ratio modification in the exchange and solution phases

Increased leaching efficiency and faster soil salinity reduction

Better soil permeability and aeration

Reduced PH in sodium-rich soils

Prevention of soil crust formation on the surface of the soil after irrigation

supply of the highly-consumed nutrients of sulfur and calcium

soil texture improvement and strengthening

reduced clay soil density and soil’s bulk density

increased water retention, improved root penetration, and increased irrigation efficiency of the soil

modification of the calcium/magnesium ratio in the exchange and solution phases

better nutrient absorption by the plant
