Should You Use Gypsum for Soil?
— Should You Use Gypsum in Every Soil? You should definitely try gypsum if a soil test indicates your clay soil is at or near neutral in acidity with a high level of available sodium. If your clay soil has a white crust on the surface, assume you have extra sodium. Gypsum is also helpful where dry clay soils are hard to work or crusty on top.
Gypsum Is Almost A Universal Soil Amendment
Abstract: Agriculture has failed to be sustainable several times in the history of the world because of soil failure (Rush, 1987). Irrigated land eventually leads to sodicity and salinity unless extreme care is taken. Gypsum is a key ingredient for the maintenance of agriculture on many types of soils and over a wide pH range including sodicity. Waste-product …

1. GYPSIFEROUS SOILS IN THE WORLD
1.1 Introduction. Gypsiferous soils are soils that contain sufficient quantities of gypsum (calcium sulphate) to interfere with plant growth. Soils with gypsum of pedogenic origin are found in regions with ustic, xeric and aridic moisture regimes (Nettleton et al. 1982). They are well represented in dry areas where sources for the calcium sulphate exist.
