Soil Acidity and : Basic Information for

Oct 11, 2021"Soil acidity" is the term used to express the quantity of hydrogen (H) and aluminum (Al) cations (positively charged ions) in soils. When levels of hydrogen or aluminum become too high—and the soil becomes too acid—the soil's negatively charged cation exchange capacity (CEC) becomes "clogged" with the positively charged hydrogen and aluminum, and the nutrients needed for plant

Gypsum offers an economic source of sulfur

Nov 26, 2021Gypsum (CaSO42H2O) is a mineral mined from sedimentary deposits created by the evaporation of saline water, where sulfuric acid comes into contact with calcium carbonate. A number of productive gypsum quarries have operated in Michigan's Lower Peninsula over the last 150 years, marketing the mineral as plaster, stucco and fertilizer.

Nature and Management of Salt

Farm water quality and treatment

High bicarbonate and carbonate levels in water can cause calcium to precipitate from the soil. This reduces the soil's exchangeable calcium content and increases soil sodicity. Magnesium can also be lost in this way. In extreme cases, the loss of soil calcium and magnesium will affect plant growth.

Understanding Gypsum

Gypsum has several beneficial effects on soil structure and soil chemistry. It is also a source of plant available calcium and sulfur. It is important to understand that gypsum does not change soil pH, even though it contains sulfur.
