PKWiU: 20 15 390
CN: 31 029 000 90
Fertilizer of uniform, light grey granules (grain class 2-5 mm, at least 92%), covered with anti-caking agents, without permanent caking characteristics. Hygroscopic. Bulk density: 0.90-1.00 kg/dm3.
POLIFOSKA® 21 includes 21% of nitrogen (N), including 8% in amides and 13% in nitrates. The fertilizer includes 4% of total magnesium (MgO) in the form of carbonate and sulphate soluble in water and 35% of sulphur trioxide (SO3), that is, 14% of sulphur soluble in water, in sulphate form. It results from the mixing of ammonium sulphate, urea and fine-ground magnesite.
The amide form of nitrogen is converted in soil into the ammonia form available for plants, and then into nitrate form. These processes are quite slow, making the nitrogen available to plants uniformly. Losses of nitrogen from soil are low, because it is not washed out of soil.
In the event of irritation of skin and eyes, wash with plenty of water. Dust masks and safety goggles are recommended. If swallowed accidentally, seek medical advice. Nontoxic, odourless, non-flammable fertilizer.
