Fertilizers

Monoammonium phosphate - due to its complete solubility, it is an excellent source of nitrogen and phosphorus in an available form that is easily assimilated by plants. Fortified with phosphorus, the formula is ideal for use both at the beginning of the growing season and during further maturation. The availability of available phosphorus is key to developing a strong root system. Especially in the early stages of development. Perfect for drip irrigation and fertigation systems, foliar feeding of plants, as well as the production of suspensions and mixtures.

Magnesium sulfate is a complex fertilizer, that is indispensable in crop production. The use of magnesium sulfate in crop production allows to achieve a significant improvement in appearance, significantly increase the yield, ensure the lush flowering of ornamental plants. Magnesium is impossible to overdose - during the growing season the plant takes as much as needed. Fertilizer residues do not form salts and remain unchanged, therefore they do not worsen the condition of the soil, but, on the contrary, improve, which contributes to high yields over several seasons. It is produced in the form of small crystals, usually white, sometimes with a grayish tint. Dissolves without residue in water, when the water temperature is above 20 degrees, the reaction occurs faster. It does not cause difficulties in transportation, but requires protection from direct sunlight and precipitation.

Magnesium nitrate «Poluks Group» - is a hygroscopic salt with the formula Mg(NO₃)₂. It is very soluble in both water and ethanol. Magnesium nitrate occurs in mines and caverns as nitromagnesite. This form is not common, although it may be present where guano contacts magnesium-rich rock. It is used in the ceramics, printing, chemical and agriculture industries. Its fertilizer grade has 10.5% nitrogen and 9.4% magnesium, so it is listed as 10.5-0-0 + 9.4% Mg. Fertilizer blends containing magnesium nitrate usually have ammonium nitrate, calcium nitrate, potassium nitrate and micronutrients; these blends are used in the greenhouse and hydroponics trade.

MKP «Poluks Group», (also potassium dihydrogen phosphate, KDP, or monobasic potassium phosphate), KH2PO4, is a soluble salt of potassium and the dihydrogen phosphate ion which is used as a fertilizer, a food additive and a fungicide. It is a source of phosphorus and potassium. The ratio of K2O to P2O5 is 34:52. Phosphorus contained in the fertilizer has a positive effect on the root system of crops, while potassium increases their resistance to stress conditions.

Potassium nitrate «Poluks Group» is a chemical compound with the chemical formula KNO3. It occurs as a mineral niter and is a natural solid source of nitrogen, provides essential nutrients quickly and extremely efficiently. Potassium nitrate is one of several nitrogen-containing compounds collectively referred to as saltpeter or saltpetre. Potassium nitrate is used in fertilizers as a source of nitrogen and potassium – two of the macronutrients for plants.

Potassium sulphate «Poluks Group» (K₂SO₄) (in British English potassium sulphate, also called sulphate of potash, arcanite, or archaically known as potash of sulfur) is a non-flammable white crystalline salt which is soluble in water. The chemical compound is commonly used in fertilizers, providing both potassium and sulfur. It is mainly used for chlorine sensitive crops (potatoes, tobacco, flax, grapes, citrus fruits, etc.). The presence of sulfate ions in the fertilizer has a positive effect on the productivity of cruciferous plants (cabbage, rutabagas, turnips, etc.) and legumes that consume a lot of sulfur. Potassium sulfate is also used in the production of glass, various alum and other potassium compounds as a flux in metallurgy.

Calcium nitrate «Poluks Group», also called Norgessalpeter (Norwegian saltpeter), is the inorganic compound with the formula Ca(NO3)2. This colorless salt absorbs moisture from the air and is commonly found as a tetrahydrate. It is mainly used as a component in fertilizers but has other applications. Recommended for fertigation, hydroponic cultivation and also for foliar feeding. It is a valuable source of easily digestible nitrogen and calcium. It does not contain heavy metals. It can also be used for the preparation of fertilizer mixtures.
