 · Calcium sulfate is good for plants but generally no one thinks of it as a source of important source of plant nutrients. Generally everyone thinks of calcium sulfate, or gypsum, as a soil amendment and it is. But it much more than that – it is also a fertilizer that has nutrient value. Gypsum is best known for improving soil structure, increasing aeration and infiltration, and it reduces ...

What other effects will gypsum have on soil and plant health? There are a number of scientific studies on gypsum usage both in the literature and on websites. Briefly, researchers have found: • Gypsum does not usually change soil acidity, though occasional reports of both increasing and decreasing pH exist; • Gypsum can increase leaching of aluminum, which can detoxify soils but also conta

The plant has three raw material storages; storage 1 which serves for line 1 stores Limestone, Shale, Silica sand, Iron ore, Pozzolana, Gypsum and limestone additive. Storage 2 which serves for line 2 stores Limestone and Shale. Storage 3 which serves for line 2 stores Correctives (Silica sand, Iron ore) and Additives (Pozzolana,

The reactive iron result indies how much of the phosphorus applied will be locked up and never become available to the plants. Reactive iron is a natural feature of the soil and cannot be changed. In my experience the phosphorus 'rule of thumb' holds when the reactive iron is around 1700 – 2500. Less than 1500 the rule of thumb could ...

 · Phosphorus concentration in plant organic material of about %. The long term decline in organic P resulting from cultivation may be less than that for organic matter as a whole.

Gypsum has 23% calcium and 18% sulfur and its solubility is 150 times that of limestone, hence it is a natural source of plant nutrients. Gypsum naturally occurs in sedimentary deposits from ancient sea beds. Gypsum is mined and made into many products like drywall used in construction, agriculture and industry. It is also a byproduct of many industrial processes.
