nitrogen is reduced, while sludge and fine particles in the wastewater are retained in the filter. All these processes are performed in one compact tank-also known as a cell. This means that a biostyr unit requires very little space compared to con 在biostyr单位相当数量有机污染物和营养素即。
Each kilogram of MAP in the tank provides 610 grams of phosphorus (P2O5) and 120 grams of ammonium-nitrogen (N-NH4). Example: from initial establishment to flowering, open-field grown tomatoes require phosphorus at a rate of 1.5 kg P2O5 per hectare per...
