Bialfoska NPK 5-15-30+4S Blend is a multi-nutrient, blended fertiliser created by mechanically mixing two types of fertiliser. This fertiliser is in the form of granules ranging from grey to pink in colour. It characterises with high content of Phosphorus(15% P2O5) and Potassium (30% K2O). This fertiliser may be applied to all field and grassland crops, especially on potassium-poor soils and to potassium-loving plants such as sugar beet, maize and oilseed rape.
The highest effectiveness is obtained when the fertiliser is applied pre-sowing, mixing it with soil to a depth of 10-15 cm. The fertiliser can also be applied as a top dressing in spring when needed. The pre-sowing dose of fertiliser can fully cover the plants’ needs for phosphorus and potassium, while nitrogen is supplied only in the amount necessary for the initial growth. The remainder of this nutrient must be supplemented in the post-sowing fertilisation.
