Ground phosphate raw material, widely used as a source of phosphorus for agricultural crops.
It has low hygroscopicity, does not cake and is well dispersed. Phosphorus obtained from phosphate rock has a long absorption period and is characterised by long-term content in the soil. The product is used for phosphoritisation – enrichment of soils with low phosphorus content with an element. Phosphorus shows maximum absorption efficiency in acidic soils (pH 4.5-5.5) and soils with high hydrolytic acidity.
It is applied at doses of 0.5-3 t/ha during primary tillage. It is most effective when applied in autumn.
