This allows for water to drain out and air to have access. Once soil is tightly packed, water and air penetration is reduced and root growth suffers. A high-analysis source of micronised natural gypsum combined in a free-flowing suspension with fulvic acid. Index Terms: Stabilization, soft clay soil, gypsum plafond waste (GPW), California Bearing Ratio (CBR) ... yield of liquid limit (LL) is 66.00 %, which means greater than 50 %. Is Gypsum good for clay soil? This product will significantly improve your turf quality and plant growth in hard or clay soils.

After 4 years of field trials, studies confirmed that the finer particles remain more active in the soil than the courser particles of "bulk gypsum". There is another similar group of products called liquid soil conditioners. The calcium ions in the gypsum displace the sodium ions from the outside of the clay particles. If you mix gypsum with the soils it will then look like a jar full of marbles, with air pockets around them. Amazon's Choice for liquid gypsum. Gypsum (calcium sulphate dihydrate) causes the small particles found in clay soil to flocculate to create larger particles. The soil conditioning capacity of gypsum is dramatically magnified with the huge increase in surface area associated with micronisation. I've applied Gypsum to my own lawn over the years (pellitized with sulfur) because of our heavy soils, also high in pH. Revive Ready-to-Spray Soil Builder, 64 oz. Clay Doctor Soil Modifier - Cutting Edge Soil Science . Sodic soils are found mainly in arid regions of the western United States. Gypsum as Soil Conditioner. 88. So, the soil is classified into MH and CH types [13]. MMS HYDRO GYP - B is a high quality, micronised Gypsum liquid suspension with a milled grain size. Salt is probably most damaging on clay soils.

Once registered and logged in, you will be able to contribute to this site by submitting your own content or replying to existing content. In healthy soils, calcium dominates over sodium and magnesium to encourage clay particles to aggregate (clump). The sodium can then be washed down through the soil. Gypsum can be the solution to your clay soil problem. Gypsum has traditionally been used as a means of improving the friability of clay soils by reducing sodium levels. Sodium can enter soil from many sources. FREE Shipping on orders over $25 shipped by Amazon. Gypsum is a soft white-grey mineral known as a ‘clay breaker’ because it helps to improve the physical condition of heavy clay soils. It is specially formulated to rapidly release excess magnesium in moderate to heavy clay soils to improve its porosity, creating an open structure, reducing compaction issues with a higher Ca:Mg ratio, which is essential for high production cropping. Clay soils in commercial agricultural sites are often treated with gypsum to help break up the clay and enhance calcium, which breaks up excess sodium. Based on ingredients, these products are the same as liquid core aerator products except they contain things like fertilizer, vitamins, plant growth hormones, and bio-stimulants.
