USE
The best efficiency is achieved by fertilizing before sowing. After spreading, the fertilizer must be mixed with the soil to a depth of 10-20 cm. In the case of sugar beet cultivation, high-dose fertilization should be avoided immediately before sowing. On land intended for sugar beet, soil enrichment requiring high-dose fertilization should be carried out in autumn. In the cultivation of autumn plants, it is possible to fertilize in the development and growth cycle of the plants before the spring vegetation begins. On permanent grasslands, it is recommended to fertilize in early spring.
If the soil needs a large amount of potassium, part of the dose should be spread after the first harvest or first grazing.
