Properties

14% phosphorus pentoxide (P₂O₅) soluble in mineral acids, including at least 55% phosphorus pentoxide (P₂O₅) soluble in 2% solution of formic acid
24% potassium oxide (K₂O) soluble in water
3% calcium oxide (CaO) soluble in water

Usage

The best effectiveness is achieved when Lubofos® PK is applied before sowing and mixed with the soil to the depth of 10-15 cm during performance of pre-sowing cultivation treatments. This fertilizer does not contain compounds that could restrict sprouting of seeds which makes sowing possible 2-4 days after fertilization. This fertilizer is suitable for all types of soil, regardless of their heaviness and reaction. As regards grassland, it is advisable to divide the recommended dose into two parts and perform first fertilization in early spring and the other after harvesting the first crop or after second pasturage.
