Both gypsum and lime are used as soil amendments. The usefulness of comparing them is limited because their function is different. Gypsum is added to clay and heavy soils to help them drain and improve their tilth, or ability to be tilled, and to remove salt from saline soils. Lime is …
detrimental to our soils and water bodies and are, at the very least, a waste of time, effort and money. Two common soil amendments used in other parts of the country are gypsum and lime. Myth #1: Gypsum is a required soil addition. Gypsum, or calcium sulfate (CaSO4∙2H2O), is water‐
4.5 Use of Gypsum. In addition to lime, gypsum, and especially the phosphogypsum (PG) produced as a by-product of phosphoric acid production, is finding an increasingly widespread use as a physical conditioner of both dryland and irrigated soils and as a chemical amendment for alleviating, by leaching the effects of subsoil acidity on root ...
April 2017 GYPSUM 1. INTRODUCTION Gypsum is the common name of hydrated calcium sulfate, which has the chemical formula CaSO 4.2H 2O. Gypsum is mainly used as a soil ameliorant to improve the structure of sodic and magnesic soils. Gypsum may also be used, at lower rates, as: • a sulfur fertiliser; • a calcium fertiliser.
source such as gypsum, or by adding an amendment such as sulfur or sulfuric acid, which will dissolve lime if it is already present in the soil. These materials can be mixed in to the surface layer of the soil or dissolved in the irrigation water. Gypsum Studies have shown that gypsum mixed in to the soil can improve soil properties.

Cooperative Extension soil resource specialist, UC Davis. DROUGHT TIP Reclaiming Saline, Sodic, and Saline-Sodic Soils Salt-affected soils cause poor plant growth, affect crop production, and reduce water use efficiency. Some salt-affected soils have physical problems that slow water infiltration and increase surface runoff.

Oct 26, 2005· Gypsum, for example, is one of the many materials that can be distributed using chemigation and irrigation fertigation systems. Gypsum has three major usages – as a soil amendment, a conditioner and a fertilizer. As gypsum is not water soluble, most pumps and irrigation systems are unable to deal with it.
Viability of lime and gypsum use in mitigating sodicity in an irrigated Vertosol John Bennettab and Stephen Cattlea aFaculty of Agriculture Food and Natural Resources, The University of Sydney, NSW 2006 bCorresponding author: [email protected] Abstract The use of gypsum, and to a lesser extent, lime to mitigate sodicity in dryland agriculture has been shown as
Repeated use of dolomitic lime, results in soils with high in magnesium but low in calcium. If you can find calcite lime, use it about every other time you apply lime. Another way to supply calcium is to use gypsum in addition to dolomitic lime. 5. The only way to be sure of what your garden needs for nutrients and pH is to have your soil

Gypsum can be found from mined material, wallboard plants, and more broadly from Electrical Power Plants that use lime material to "scrub or de-sulfurize" flue gas in the energy making process. Gypsum in differing forms can be found in the United States as well as many other countries.

The use of gypsum, and to a lesser extent, lime to mitigate sodicity in dryland agriculture has been shown as viable. However, under an increased water application (i.e. irrigation) the dissolution of gypsum could be expected to be more rapid. Lime, due to a lower solubility, could provide a more constant source of calcium to the soil, especially when applied in combination with gypsum.
