Phosphate rock-a natural source of phosphorus
* it is used as a meliorant and can solve the problem of lack of mobile phosphorus in the soil
• optimal fertilizer to increase the availability of soil phosphorus
* phosphate rock improves soil structure, water-physical characteristics and nutrient migration
* application of phosphate rock provides optimal phosphate regime of the soil, mandatory for full and effective action on plants of nitrogen and potash fertilizers and the formation of a full-fledged crop quality
* numerous vegetation experiments have shown that phosphorite flour of fine grinding, particles smaller than 100 microns was 2.2 times more effective than phosphorite flour of coarse grinding with a granule size from 100 to 310 microns. Increase yields from the phosphate flour to a coarse grind was only 34.7 per cent compared to the flour fine grinding.

Phosphorus, phosphate rock:
* Natural phosphorus soluble in weak soil acids
* The effect of phosphorus is maintained for 5-7 years, which allows to reduce the dose of phosphorus fertilizers in subsequent years
• 2-3 times faster increases the availability of soil phosphorus*
* Can significantly reduce the cost of water-soluble phosphate fertilizers
* As soil acidity increases, phosphorus efficiency increases
* Phosphorus losses and transition to hard-to-reach phosphates of iron and aluminum are excluded (reduction of losses to 63 %*)
* Allows to reduce the dose of nitrogen fertilizers by 20-30%, due to increased digestibility due to the presence of calcium
* Contains macronutrients Ca, Mg (needed in large quantities for potatoes, vegetables and other crops)
* Contains trace elements Fe, Cu, Mo, Zn, which contribute to the increase in the size and quality of the crop
• Reduces the harmful for plants and microorganisms acidity of soil
* (compared to water-soluble forms of phosphorus)

Calcium in the composition of phosphate rock
* Phosphorus and calcium increase the mobility of molybdenum, which is part of nitrate reductase, which accelerates the conversion of nitrates inside plants into ammonium form
* Seeds grown with a sufficient amount of calcium have greater germination energy and Amity of germination
* Calcium plays an important role in the photosynthesis and movement of carbohydrates, in the process of nitrogen assimilation by plants
* Calcium is involved in the formation of cell membranes and strengthens the cell structure
* In the presence of calcium in the soil solution, normal conditions for the development of the root system are created
* Calcium inhibits the flow of h+ ions, the high concentration of which has a negative impact on the physical and chemical state of the cytoplasm of root cells
* With an increased amount of calcium plants are able to tolerate more acidic soil reaction

* MD 1000 kg.
