Usage

The best effectiveness is achieved when Lubofoska® 5-10-15 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 components 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 spring, in one-time application according to the dose of phosphorus and potassium intended for the entire vegetation period.
