Soil salinity and pH, which are among the very important factors in agricultural efficiency, will be discussed next

Agricultural gypsum effects on soil salinity

Water and soil salinity inflict considerable losses on agricultural and horticultural production. Among the dominant soil cations, sodium ions have a direct relationship with salinity. i. e, increases in soil salinity lead to higher sodium ion concentrations. The soils in the region are divided into the three categories of saline soils, saline- sodic soils and sodic soils. based on the ratios between the ions present in the soil determined by soil salinity.

The distinct characteristic of saline soils is reduced plant growth and yield. and that of sodic soils is lower water infiltration rates into the soil. whereas saline- sodic soils exhibit a combination of these problems. Presence of salts (salinity) in soil decreases soil water potential. Compared to soils with higher salinity, in soils with lower salinity water moves towards plant roots.

Consequently, presence of salts in soil prevents water entry into plant roots. Agricultural gypsum can be applied to remediate saline soils. This natural material, which is cheaper than other chemicals, must be plowed deep into the soil and irrigated heavily. This will move the elements in gypsum, which is somewhat water soluble, towards plant or tree roots. Finally, soil salinity around the roots decreases while absorption of various elements increases.

Effects of gypsum on soil pH

Soil pH is a very important soil characteristic. because it determines the capacity for plant growth, availability of nutrients, bacterial activity and soil physical conditions. If soil is too acidic or too alkaline, maybe nothing will grow in it. There is a specific pH range required for each plant species to grow. One of the most important agricultural gypsum features is that it adjusts soil pH into the ideal range for plants.

Gypsum can indirectly affect soil pH by improving soil structure and nutrient availability. When gypsum is added to soil, it can improve soil structure by reducing soil compaction and improving water infiltration. This, in turn, can enhance root growth and nutrient uptake by plants. As a result, plants may be able to access nutrients more effectively, which can lead to improved growth and productivity.

Additionally, agricultural gypsum contains calcium and sulfur, both of which are essential nutrients for the plant and its growth. As the agricultural gypsum dissolves in the soil, it releases these nutrients (calcium and sulfur). which can help to improve the soil fertility and plant growth. This can indirectly affect the soil pH by promoting healthy plant growth and nutrient uptake.
