It is best to fertilize with Lubofos® 5-10-25 before sowing, and after application, blend the fertilizer with the soil to the depth of 10-20 cm. This fertilizer does not contain components that could restrict sprouting of seeds which makes it possible to apply it immediately before sowing the cultivated plant. However, in spring fertilization of sugar beets, the fertilizer has to be put into the soil 10-14 days before sowing the seeds, especially in case there is applied single, large dose of the fertilizer. 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.
