Principles of application
Polifoska® NРК(S) 6:20:30+7 is suitable for all types of soils and crops, but it is the most effective on potassium-depleted soils.
Fertilizer is applied as a basal fertilizer. It also can be used as a component of fertilizers mixtures in farming prepared just prior to application.
As the basal fertilizer Polifoska® NРК(S) 6:20:30+7 is applied in autumn-summer period as well as in spring. It is free flowing fertilizer which is better to incorporate into the depth of up to 25 cm.
Basal fertilization under fruit and berry crops is to be made prior to ploughing for better mixing with soil either in planting holes or trenches. Doses of fertilizer are the same when it is applied in planting holes or trenches, but total surface area should be recalculated to fertilized area.
Perennial plantings feeding is applied in spring prior to resumption of active vegetation, after harvesting or growth cessation. Summer feeding after harvesting can cause plant regrowth or weakening before repose.
