Polifoska 5 (5-15-30) Grupa Azoty - NPK fertiliser

Polifoska 5 Grupa Azoty - NPK fertiliser

Advantages of using Polifoska 5 fertiliser, Grupa Azoty:

• Nitrogen, thanks to the use of ammonium form, is not leached from the soil. Plants absorb it slowly. It limits excessive potassium uptake and supports phosphorus uptake.
• Phosphorus is in the form of ammonium phosphate. This is the best assimilated form of this nutrient by cultivated plants and is well absorbed even in conditions of water deficiency in the soil.
• Plants are well rooted, and their development is proper and proportional from the emergence period.
• When applied pre-sowing, it increases plant resistance to frost and drought.
• It positively affects full flowering and uniform ripening.
• Improves quality and ensures high yield.

Polifoska 5 is a comprehensive compound fertiliser for pre-sowing application (it is recommended to mix with soil to a depth of 10‑20 cm) for all cultivated plants: winter and spring cereals, oilseed rape, maize, root crops, grassland, as well as in vegetable and orchard cultivation. Polifoska 5 fertiliser can also be used as top dressing for winter crops in early spring.

Polifoska 5 NPK fertiliser is especially recommended for use on very poor and potassium-deficient soils (mainly medium and light soils), under conditions of low organic fertilisation, for potassium-loving plants (e.g. sugar beet, potato, maize and oilseed rape).
