clay from gypsum


The clay particles may then move through the soil, clogging pores and reducing infiltration and drainage. The calcium from gypsum displaces the sodium which can then be leached deeper into the soil. South Australian production of agricultural gypsum exceeded 300 000 tonnes in 2002 representing a 400% increase over 8 years.

Tight Clay Soils, Calcium Sulfate

Clay soils tend to have a high CEC. GYPSOIL is calcium sulfate dihydrate (CaSO 4 • 2H 2 O). It dissolves (dissociates) with moisture into free calcium The remaining Ca from the gypsum then attaches to the exchange sites, replacing the excess Mg, Al, Na, etc. in the soil complex. This is what sets the stage for improved soil structure

Estimating mineral abundances of clay and gypsum mixtures

The gypsum used in this study was coarse and poorly sorted gypsum sand collected near White Sands, NM, and the montmoril- lonite was sample SAz-2 obtained from the Clay Minerals Society (CMS). Though the CMS offers several different montmorillonite samples, the SAz-2 variety was chosen for this work because the

Gipsum adalah salah satu contoh mineral dengan kadar kalsium yang mendominasi pada mineralnya. Gipsum yang paling umum ditemukan adalah jenis hidrat kalsium sulfat dengan rumus kimia CaSO 4.2H 2 O. Gipsum adalah salah satu dari beberapa mineral yang teruapkan. Contoh lain dari mineral-mineral tersebut adalah karbonat, borat, nitrat, dan sulfat.Mineral-mineral ini diendapkan di laut, danau, gua

Gypsum and Clay Soils

Gypsum aids the clay particles to lump together (it's a chemical reaction/bonding kind of thing beyond the scope of this page) Bottom line – adding gypsum helps the tiny particles to group together to form larger particles and because you have larger particles, you have more air space and water movement.

Richgro 15kg Natural Gypsum Clay Breaker

Breaks clay; For s; Designed for use on s, Richgro Natural Gypsum Clay Breaker helps improve the physical condition of heavy clay soils. Soil particles are brought together into clumps, thus enabling better water penetration.


clay particles together, so by replacing sodium with calcium on exchange sites, gypsum can stabilize a sodic soil and improve soil structure. Calcium in gypsum replaces sodium on clay surfaces and improves soil structure. Gypsum rate is determined from the amount of calcium required to reduce ESP to 6.

Natural Gypsum Clay Breaker s. Available in 10kg and 15kg bags.

The Loam Ranger

The higher the clay content, the worse is the erosion risk. Similarly, soils that have a high silt content, like yours, are still highly erodible, because the fine silt is easily carried away by moving water and is not responsive to gypsum: it has very little cation exchange capacity, so gypsum will not stop dispersion.

Clay soil gypsum — BBC Gardeners' World Magazine

Gypsum helps to bind the tiny clay particles together to form larger ones (a process called flocculation), but it doesn't really stabilise the soil structure in the same way that bulky organic matter does. It doesn't always work on all clay soils either.


Van Alphen and de los Rios Romero (1971) mentioned that in the fine-textured soils of the Ebro Valley of Spain, with 40 percent clay and 1 to 9 percent gypsum, the available moisture was higher, ranging from 23 to 38 percent in the non-gypsic surface layers. These figures of available moisture are considered high even for non-gypsiferous soils.

Do I need to apply gypsum?

Gypsum is only effective in stabilising chemically unstable soils in the short term and does little to improve the structure of clays that are not sodic– where in this case, farmers have commented on the benefits of adopting zero tillage to improve soil structure; Generally, soils with less than 15% clay show little response to gypsum.

Yates Gypsum Clay Breaker, improving soil structure

Yates Gypsum Clay Breaker is a soil conditioner for improving the structure of compacted clay soil. Helps modify hard compacted clay soil into more open pliable soil. This allows water to better penetrate the soil and increases aeration, thus benefiting the soil structure.


Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 2H 2 O. 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.A massive fine-grained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures including

Horticultural Agricultural Gypsum, Soil Improver for Clay

Great for conditioning clay soil without increasing soil alkalinity. It is ideal if one can sieve the soil and then add the gypsum, but if you aren't as OCD as I am, then digging it in well also does the trick. It stops clay soils from clumping, so improves drainage and the problem of having heavy, sticky soil when wet or like concrete when dry.

Garden Gypsum Information. As a rule, using gypsum for garden tilth will probably not harm your plants, but it simply is not necessary. Using a little elbow grease and lovely organic goodies from fall clean up or compost worked into the soil to a depth of at least 8 inches

How to Amend Clay Soil: 13 Steps (with Pictures)

28.03.2019Most clay soils are on the alkaline side, meaning that you'll probably want to lower the pH of the soil. There are several ways to do this. The most common substances to add to clay soil are builder's sand, gypsum, composted manure, compost or other coarse organic material.

The Role Of Gypsum In Agriculture: 5 Key Benefits You

"Clay dispersion and collapse of structure at the soil-air interface is a major contributor to crust formation," he said. "Gypsum has been used for many years to improve aggregation and inhibit or overcome dispersion in sodic soils." Soluble calcium enhances soil aggregation and porosity to improve water infiltration (see below).

As we have previously stated, this process requires specialized knowledge and costly, complex application equipment, it is NOT a product in a bag or bottle a homeowner can apply themselves.There are soil treatment products like gypsum that a homeowner can apply themselves, but they take 2 to 3 years to work and only treat the surface area.
