GYPSUM IN AGRICULTURE - Smart Fertilizer

Some soils, usually in semi-arid regions, suffer with very high concentration of salts and sodium, mostly due to high evaporation, low rainfall and lack of drain ability. Gypsum is used in these cases as a soil corrective agent, because it improves drainage, allowing the water to move into the soil and leach the excess minerals.

Influence of lime and gypsum on long-term rehabilitation

This paper determines the influence of lime and gypsum on the rehabilitation of a degraded sodic soil in a semi-arid environment 12 years after appliion. The aim was to assess rehabilitation strategies for sodic soils as alternatives to the appliion of gypsum alone. An experimental site was used where lime and gypsum coinations (L0G0, lime 0 t ha–1 and gypsum 0 t ha–1; L0G1, L0G2.5

Arid Soils - an overview | ScienceDirect Topics

While the uses of lime and gypsum have ancient origins, another interesting approach in recent decades has been the use of various oxides of iron to promote aggregation in low-organic-matter soils. In the 1970s researchers added iron oxides to increase aggregate stability of soils and found peak aggregation at a 2% addition rate, with aggregation favored by acidic conditions.
