Bulk density: between 1.0 and 1.1 kg / dcm3
FEATURES
12% phosphorus pentoxide (P2O5) is soluble in mineral acids
10% phosphorus pentoxide (P2O5) soluble in neutral ammonium citrate solution and water
9% phosphorus pentoxide (P2O5) is soluble in water
24% potassium oxide (K2O) is soluble in water
14% calcium oxide (CaO) is soluble in water

USE
For best efficiency, it is recommended to use before sowing. After use, mix with soil to a depth of at least 10-15 cm. In perennial plantations, the most suitable period for fertilization is the spring growth and development of plants. If a large dose is required, it is recommended to use part of the dose after the first harvest / grazing.
