Potassium sulphate (K₂SO₄)

Potassium sulfate (SOP – sulfate of potash), which is planned to be obtained within the framework of the project, is an independent potassium fertilizer. It is used for both the main and pre-sowing application, fertilizing agricultural and ornamental plantings grown in open and protected ground on all types of soils. Recommended for cruciferous crops (collard and cauliflower, broccoli, kohlrabi, watercress, spinach, Brussels sprouts, arugula, radishes, turnips or forage turnips, rutabaga), vegetables (pepper, eggplant, tomato, cucumber, etc.) and simply gray-loving crops: oilseed rape, sunflower, onion, garlic, etc. Potassium sulfate is used primarily for crops sensitive to chlorine (potatoes, tobacco, flax, grapes, citrus fruits, etc.), which reduces the safety of harvested agricultural products.
In the world, the main raw material for the production of potash fertilizers are sylvins (compounds of potassium and chlorine), therefore, the technology for obtaining potassium sulfate often does not allow to completely get rid of chlorine, and additional cleaning operations are expensive and time consuming. The technology developed by OOO Baikal Nedra Geo makes it possible to immediately produce a premium-class product that does not contain chlorine-ion, since this element is absent in the feedstock, and additional purification steps are not required in comparison with standard approaches to SOP production.
