Ammonium Sulphate fine (1000) 25kg
Description
The effect of sulfuric acid ammonia (ammonium sulphate) can be characterized as medium fast by the ammonium sulphate. Plants can absorb nitrate directly, while the majority of ammonium must first be converted to nitrate via soil reactions. The speed of this conversion(*) depends on soil temperature and soil moisture. Ammonium nitrogen forms a compound with soil particles (e.g. clay minerals and organic matter) and is therefore less sensitive to leaching during conversion.
