Product categories: scientific name: ammonium sulfate; Referred to as: ammonium sulphate; Commonly known as: ammonium sulphate.
Molecular formula: (NH4) 2 so4
Molecular weight: 132.13
Appearance: white or grey granular or powder,
Physical and chemical properties:
Ammonium sulfate [(NH4) 2 so4, including N: twenty - 21%] referred to as ammonium sulphate, commonly known as ammonium sulphate. Ammonium sulphate product is generally white crystal, by-products or mixed impurity with light yellow, gray and noise,
Nitrogen (twenty ~ 21) %, physical properties stable, high decomposition temperature was 280 ℃), is not easy to absorb moisture, critical moisture absorption point in relative humidity 81% (twenty ℃), soluble in water, when 0 ℃ 70 g / 100 g water,
Fertilizer effect of rapid and stable. Ammonium sulphate in addition to nitrogen outside, still contain 24% of sulfur, also is a kind of important application. In the long-term application does not contain sulfur high concentrated chemical fertilizer area, soil lack of sulfur increasingly
Generally, this makes the region the ammonium sulphate as an important source of added soil sulfur. Ammonium sulphate also contain a small amount of free acid and other crop nutrient.
Chemical properties:
Ammonium sulphate in chemical properties are the main characteristics of the molecules containing anion SO42 -, difficult to be soil particles holding, and because of crops on NH4 + more absorption and make SO42 - residual soil. so
Ammonium sulphate is a kind of typical physiological acid nitrogen fertilizer. SO42 - in including free CaCO3 of calcareous soil, very easy and CaCO3 or and soil colloid parent one.the Ca2 + react, form difficult
Soluble CaSO4, will not significantly affect the soil pH value. But to neutral and acidic soil, residual SO42 - and H + will be combined and reduce the soil pH value, soil acidification. Continuous large
Use, need to use fertilizer such as lime measures to eliminate the side effects.
USES: mainly used for ammonium sulfate by-prod |
