NPK 4-12-32 Polifoska 4 Fertiliser 50kg

POLIFOSKA 4 is a compound fertiliser particularly dedicated to potassium-loving crops such as: sugar beet, potato, maize and oilseed rape

Its composition includes:

4% nitrogen in ammonium form
12% phosphorus pentoxide (P2O5) soluble in ammonium citrate and water
10% phosphorus pentoxide (P2O5) soluble in water
32% potassium oxide (K2O) soluble in water
2% magnesium oxide (MgO)
9% sulphur trioxide (SO3) soluble in water.

POLIFOSKA 4 is recommended for pre-sowing and top dressing fertilisation for all cultivated plants: winter and spring cereals, industrial and root crops, grassland, as well as in vegetable growing and orcharding.

The largest amounts of potassium are taken up by plants during their intensive growth phases.

Potassium positively affects the plant by:

tillering and producing new stems,
enhancing water uptake by the plant and its storage, increasing drought resistance,
increasing the content of protein, sugar, starch, pectins and fats in the plant.
increasing frost resistance and preventing lodging.

Bulk density is 0.9-1.0 kg/dm3.
