In addition, the re-use of gypsum by-products from coal power plants reduces the need to mine gypsum from geologic deposits. It also saves landfill space. Gypsum can’t solve every agricultural problem, but it is a proven resource to add nutrients and improve soil structure.
What is gypsum from coal?
Gypsum that comes from coal plants is called flue-gas desulfurization gypsum, as it comes from the process that ‘scrubs’ sulfur out of the smoke stacks to reduce air pollution. “The gypsum that is recovered has good quality,” says Dick. “The gypsum particles are small and uniform in size making them quite reactive.
What is the chemical formula of gypsum?
Chemically speaking, gypsum is calcium sulfate. Its use is often confused with that of lime, which is calcium carbonate.
Does gypsum affect soil pH?
Gypsum will change soil pH very slightly , yet it can promote better root development of crops, especially in acid soils, even without a big pH change. This is because the gypsum counteracts the toxic effect of soluble aluminum on root development. Aluminum occurs naturally in soil and often isn’t a problem for crops. But when soil becomes acidic, the aluminum is available to plants—and it can stunt or kill them.
Is gypsum a good source of sulfur?
When roots are more abundant and can grow deeper into the soil profile, they can take up more water and nutrients, even during the drier periods of a growing season. Although moderately soluble, gypsum can be an excellent source of sulfur over several growing seasons.
Is gypsum soluble in calcium?
Another bonus of gypsum is that it is a moderately-soluble mineral. This means the calcium can move further down into the soil than the calcium from lime (calcium carbonate). This can inhibit aluminum uptake at depth and promote deeper rooting of plants.

Does gypsum help soil?
USA Gypsum agricultural products provide sulfur and calcium for a more healthy soil for your crops. Calcium improves soil structure, aeration and drainage, resulting in increased water infiltration and reduced soil surface crusting and improved seedling emergence.
Why is gypsum used in soil?
Gypsum improves water infiltration rates into soils and also the hydraulic conductivity of the soil (Shainberg et al. 1989). It is protection against excess water runoff from especially large storms that are accompanied with erosion.
Why is gypsum important?
Gypsum provides calcium which is needed to flocculate clays in acid and alkaline soil (Shainberg et al. 1989, Sumner 1993, Sumner and Miller 1992). It is the process in which many individual small clay particles are bound together to give much fewer but larger particles. Such flocculation is needed to give favorable soil structure for root growth and air and water movement.
How does gypsum prevent crusting?
Gypsum can decrease and prevent the crust formation on soil surfaces which result from rain drops or from sprinkler irrigation on unstable soil (Shainberg et al. 1989; Sumner and Miller 1992). It can even prevent crusting that results when acid soils are limed (Sumner 1993), the gypsum is coapplied with the lime. The gypsum is either surface applied or put on in the irrigation system. Prevention of crust formation means more seed emergence, more rapid seed emergence, and easily a few days sooner to harvest and market. Seed emergence has been increased often by 50 to 100 percent. The prevention of crusting in dispersive soils is a flocculation reaction.
How is gypsum used in soil reclamation?
The most economical way is to add gypsum which supplies calcium. The calcium replaces the sodium held on the clay-binding sites. The sodium can then be leached from the soil as sodium sulfate to an appropriate sink. The sulfate is the residue from the gypsum. Without gypsum, the soil would not be leachable. Sometimes an ESP of three is too high, but sometimes up to ten or more can be tolerated. The range is partly the result of concentration of soluble salts.
What is the mechanism that binds soil organic matter to clay in soil?
Gypsum is a source of calcium which is a major mechanism that binds soil organic matter to clay in soil which gives stability to soil aggregates (Muneer and Oades 1989). The value of organic matter applied to soil is increased when it is applied with gypsum.
Why is gypsum used in irrigation?
Gypsum is used to increase the solute concentration of low-solute water used for irrigation (Traynor 1980). Irrigation water from rivers that no longer have sources of leachable salts wither penetrates poorly into soil or causes soil particles to degrade which results in low-water penetration.
What are the advantages of gypsum?
Advantages of gypsum in addition to prevention and correction of sodicity include greater stability of soil organic matter, more stable soil aggregates, improved water penetration into soil, and more rapid seed emergence. The need for gypsum in amounts varying from small to large is almost universal.

Gypsum is the most commonly used amend- ment for sodic soil reclamation and can also be included as a component in synthetic soils for nursery, greenhouse, and landscape use .
What are the benefits of gypsum?
Such amendments promote soil aggregation and thus can (1) help prevent dispersion of soil parti- cles, (2) reduce surface crust formation, (3) promote seedling emergence, and (4) increase water infiltration rates and movement through the soil profile. It can also reduce erosion losses of soils and nutrients and reduce concentrations of soluble phosphorus in surface water runoff. Chemical properties improved by appli- cation of gypsum include the mitigation of subsoil acidity and aluminum toxicity. This enhances deep rooting and the ability of plants to take up adequate supplies of water and nutrients during drought periods. Gypsum is the most commonly used amend- ment for sodic soil reclamation and can also be included as a component in synthetic soils for nursery, greenhouse, and landscape use.

What is Gypsum?
Gypsum is calcium sulfate dihydrate (CaSO 4 2H 2 0). Flue gas desulfurization (FGD) gypsum, such as GYPSOIL ® brand gypsum, is a co-product material derived from the scrubbing of flue gas emissions in coal-burning power plants. Gypsum can be spread with lime and litter spreaders. Gypsum is not acid soluble and will not change the soil pH. It helps to shift the Ca and Mg levels in soil and offers a readily available form of sulfate sulfur, a valuable secondary nutrient that benefits the soil and crop. The sulfate in gypsum binds with excess Mg in the soil to form soluble Epsom salt, which moves lower into the soil profile. This Mg is replaced by Ca, improving water holding capacity, root development and soil quality.2
What is Ag lime?
Ag lime is an acid-soluble material that is applied to cropland to raise the pH of acidic soils. It comes in many forms including calcium carbonate (CaCO 3 ), magnesium carbonate (MgCO 3) and others. It can be applied in a single pass with a lime spreader. Acidic soils trigger a chemical reaction allowing carbonate molecules to strip H+ molecules …
What is the nutrient exchange capacity of soil?
Important cations include calcium (Ca++), hydrogen (H+), magnesium (Mg++), potassium (K+), sodium (Na+) and ammonium (NH 4 +). Different soil types have different nutrient holding capacities. As an example, clay soils generally have more exchange sites than sandy soils. In general, properly balanced soils have a desired range for each of these nutrients. In a balanced soil, Ca++ and Mg++ should take up about 85 percent of the exchange sites collectively. The remaining 15 percent are open for other cations.3 Look for soil test results showing a base saturation, or percentage of nutrient holding sites occupied by cations, of 70-80 percent for Ca and 10-13 percent for Mg. If Ca or Mg base saturations are outside of the ideal range, soil productivity is hindered and problems may exist with compaction, sodic conditions, crusting, poor draining and more. Negatively-charged clay particles form strong bonds with Ca++. The resulting aggregated particles form pore spaces so air, water, soil bacterium and roots move more freely through the soil profile. Alternately, Mg++ forms weak bonds with clay particles. Even rain droplets can break the bonds, displacing the soil and blocking the pathways for water, nutrients, roots and air in the soil. Compaction, crusting problems and waterlogging are common when the Mg levels are too high and/or Ca is too low. This is why the desired base saturations of Ca and Mg must be attained.
Can gypsum be spread with lime?
Gypsum can be spread with lime and litter spreaders. Gypsum is not acid soluble and will not change the soil pH. It helps to shift the Ca and Mg levels in soil and offers a readily available form of sulfate sulfur, a valuable secondary nutrient that benefits the soil and crop. The sulfate in gypsum binds with excess Mg in …
Which soil has more exchange sites?
As an example, clay soils generally have more exchange sites than sandy soils. In general, properly balanced soils have a desired range for each of these nutrients. In a balanced soil, Ca++ and Mg++ should take up about 85 percent of the exchange sites collectively.
