Why is gypsum important for farmers?

Farmers have to manage their soil well in order to maintain good crop yields year after year. Improving soil structure helps farmers with some common agricultural problems. Adding gypsum to the soil reduces erosion by increasing the ability of soil to soak up water after precipitation, thus reducing runoff.

Why is gypsum used in power plants?

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.

What is gypsum soil amendment?

What is gypsum used for?

Gypsum is a unique material that performs well as a soil amendment . Gypsum, chemically known as calcium sulfate dihydrate (CaSO 4 • 2H 2 O) readily dissolves to release calcium ions (Ca +2) and sulfate-sulfur ions (SO 4-2 ).

Gypsum and Lime Both Improve Soil Conditions But They Have Vast Differences

Ag lime and gypsum are excellent soil amendments that can be used separately, together, or in a rotation to improve soil conditions. However, understanding the differences between lime and gypsum, and how they impact soil chemistry, is important when choosing the right amendment (s) to achieve a more balanced soil.

What is Agricultural 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.

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.

Key Terms

Soil pH: A measure of acidity or alkalinity of soil, relative to the amount of hydrogen atoms presents. On a scale of 0-14, a pH around 7 is neutral, lower numbers indicate acidic conditions, greater numbers are more alkaline. The soil pH can limit yield potential and nutrient availability. Many plants thrive when soil pH is around 6.2-6.8.

Why pH Matters

Soil pH is a measure of the active hydrogen (H+) ions in the soil, a key component of many of the chemical processes related to soil health. Acidic soils, or soils with excess H+, can limit the crops’ ability to reach its genetic potential by limiting nutrient availability and soil biological activity throughout the growing season.

Proper Levels of Calcium and Magnesium

The Cation Exchange Capacity (CEC) in soil measures the nutrient holding capacity, or the number of exchange sites in a given volume of soil that attract positively charged cations or nutrients. Important cations include calcium (Ca++), hydrogen (H+), magnesium (Mg++), potassium (K+), sodium (Na+) and ammonium (NH 4 +).

Choosing Lime, Gypsum or Both

When choosing to use lime, gypsum, or both products, start with accurate soil test results, including the soil pH, CEC, organic matter and the base saturation numbers for Ca and Mg in each field. These results will help you select the proper treatment. Here are a few scenarios to consider:

Where is gypsum found?

Commercial quantities of gypsum are found in the cities of Araripina and Grajaú in Brazil; in Pakistan, Jamaica, Iran (world’s second largest producer), Thailand, Spain (the main producer in Europe), Germany, Italy, England, Ireland and Canada and the United States.

How is gypsum formed?

Gypsum is also formed as a by-product of sulfide oxidation, amongst others by pyrite oxidation, when the sulfuric acid generated reacts with calcium carbonate. Its presence indicates oxidizing conditions. Under reducing conditions, the sulfates it contains can be reduced back to sulfide by sulfate-reducing bacteria. This can lead to accumulation of elemental sulfur in oil-bearing formations, such as salt domes, where it can be mined using the Frasch process Electric power stations burning coal with flue gas desulfurization produce large quantities of gypsum as a byproduct from the scrubbers.

What is gypsum crystal?

It also forms some of the largest crystals found in nature, up to 12 m (39 ft) long, in the form of selenite.

How is synthetic gypsum recovered?

Synthetic gypsum is recovered via flue-gas desulfurization at some coal-fired power plants. It can be used interchangeably with natural gypsum in some applications.

Why is gypsum green?

Green gypsum crystals from Pernatty Lagoon, Mt Gunson, South Australia – its green color is due to presence of copper ions.

What is the chemical formula for gypsum?

Alabaster. Fine-grained, slightly colored. Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO. 4·2H2O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard / sidewalk chalk, and drywall.

Where is gypsum deposited?

Gypsum is deposited from lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate solutions in veins. Hydrothermal anhydrite in veins is commonly hydrated to gypsum by groundwater in near-surface exposures. It is often associated with the minerals halite and sulfur.

What Is Gypsum Used For Globally?

Gypsum is the most commonly utilized sulfate mineral mined across the world. Amongst other things, it’s used in the building trade to make up drywall, plaster, and building blocks. It’s even used to produce writing chalk, as a food additive, and, in its fine-grained alabaster variety, it’s made into ornamental sculptures.

Why Is Gypsum Used in Gardening?

The granular or powdered form of gypsum specifically marketed towards garden use has a variety of different applications.

How Much Gypsum Should Be Used?

Applying too much gypsum to your garden soil can be problematic. To minimize any problems, you should first establish if your soil will benefit from any addition, and you should carefully follow any pack instructions.

Why Gypsum Might Not Be the Best Solution

Over-application of gypsum can strip essential nutrients from your soil, and this can harm plant growth. It can also strip out too much sodium from soils that are already low in salt.

What Are the Other Alternatives?

There have been studies that have suggested that providing your soil has at least 10% organic matter, there will be no major benefit from adding gypsum.
