Description
Polifoska Krzem 50kg fertiliser with uniform light grey to dark grey or light pink granules, grain size class 2‑5 mm, at least 90%. Coated granules, not permanently caking. Bulk density: 0.94‑0.99 kg/dm3.
Polifoska Krzem NPK(S) 6-12-34-(10) 50kg Components:
- 6% nitrogen (N) in ammonium form
- 12% phosphorus (P2O5) soluble in neutral ammonium citrate and water, i.e. available in the form of mono- and diammonium phosphate, including 10% water-soluble,
- 34% potassium (K2O) water-soluble, in the form of potassium chloride, i.e. potassium salt
- 10% sulphur trioxide (SO3) water-soluble, in the form of sulphate.
- also contains essential plant-available silicon 0.5% (Si), equivalent to 1% SiO2.
Polifoska Krzem 50kg Purpose and use :
The fertiliser is recommended for all cultivated plants: winter and spring cereals, industrial and root crops, on grassland and in vegetable cultivation and orchards. It is recommended for very poor and poor potassium soils (mainly light and medium soils), under conditions of low organic fertilisation and for potassium-demanding plants such as: sugar beet, potato, maize and oilseed rape. The highest efficiency is achieved by applying POLIFOSKA® KRZEM before sowing, mixing with soil to a depth of 10‑20 cm. This fertiliser can also be applied in early spring as top dressing for winter crops. Perennial crops should be fertilised in spring. POLIFOSKA® KRZEM can be mixed immediately before spreading with urea, ammonium nitrate and calcium ammonium nitrate, and at any time with potassium salt.

*depending on the expected yield, calculate the POLIFOSKA® KRZEM dose, for example maize grain yield 8 t/ha on medium phosphorus and potassium soil, it is recommended to apply 67 kg POLIFOSKA® KRZEM per 1 tonne of expected grain yield (table reading) x 8 = 536 kg/ha POLIFOSKA® KRZEM or for example potato tuber yield 30 t/ha on medium phosphorus and potassium soil cultivated with 25 t/ha manure, apply 60 kg POLIFOSKA® KRZEM per 10 tonnes of expected tuber yield (table reading) x 3 = 180 kg/ha POLIFOSKA® KRZEM;
1- if soil availability is unknown, doses for medium availability soil are recommended until soil analysis is performed;
2 - kg/ha potassium salt 58-60%;
3 - recommended manure dose for potato 25 t/ha, for maize for silage and beet 35 t/ha.
