German ammonium sulfate

Hydrospeed 21Hydrospeed 2121-0-0+24S Ammonium sulfate N 21% + S 24% Hydrospeed 21 fully water-soluble fertilizer contains two nutrients in a ready-to-absorb form for use in fruit farms, vegetable crops, and dense plantings. Free from chloride and urea, characterized by its acidic effect (pH 5.2). It is one of the richest fertilizers in nitrogen in the form of ammonium (NH4), which resists leaching or volatilization as it is absorbed onto the surface of soil particles and negatively charged colloids close to the roots. It is also one of the richest fertilizers in sulfur in the form of sulfate (SO4), which acts as a companion element in nitrogen assimilation and protein synthesis processes. Ammonium sulfate is preferred for use in alkaline and calcareous soils. It is recommended to add it to pesticide and fungicide spray solutions and herbicides to adjust the pH, especially when water alkalinity is high due to the presence of bicarbonates (HCO3). It can be added alone or mixed with water-soluble fertilizers through drip irrigation or pivot sprinklers in alkaline and calcareous soils. It can be blended with all water-soluble fertilizers and most agricultural pesticides applied as foliar sprays — a side test is recommended to be conducted separately.
