Chilisai direct application rock phosphate (“Chilisai DAR”) is a high efficiency, environmentally friendly, slow release mineral phosphate fertilizer. It can also be used as a soil improver on acidic and neutral soils.
It is produced by grinding of upgraded nodular phosphate rock of Chilisai Phosphate Deposit (Aktobe oblast, Republic of Kazakhstan). The grinding is performed using vertical shaft impact autogenous mill with air classification. This grinding technology performs mechanical activation (micro-cracks) improving availability of P nutrient to plants.
Chilisai DAR is used in all types of soils with low content of available phosphorus. It is especially effective in acidic soils and in irrigated fields.
The Chilisai DAR does not contain heavy metals such as Cd and As. It has been approved for use in Organic Agriculture.
Chilisai rock phosphate is 100% natural source of P nutrient, which can be used for most stringent Organic crops techniques!
Chilisai DAR contains no less than 17% of P2O5, the P nutrient.
Typical chemical analysis of Chilisai DAR, per cent:
P2O5 - average 18%, CaO - 31%, MgO - 1%, Fe2O3 - 2%, Al2O3 - 2%, CO2 - 3%, SO3 - 1%, K2O + Na2O - 1%
