Usage

The best effectiveness is achieved when Lubofoska® 4-12-12 is applied before sowing and mixed with soil to the depth of 10-20 cm during performance of pre-sowing cultivation treatment. This fertilizer does not contain compounds which could restrict sprouting of seeds which makes sowing possible 2-4 days after fertilization. On grasslands this fertilizer should be applied as top dressing and sown in early springs, in one-time application according to the dose of phosphorus intended for the entire vegetation period. In fruit farming, fertilization should be performed after fruit picking. In vegetable cultivations, this fertilizer should be sown during station preparing treatment.
