Ammonium Sulfate Is Suitable For Various Soils And Crops

Tianjin BRG Products Co.,Ltd | Updated: Sep 21, 2017

Ammonium sulfate referred to as ammonium sulfide, colorless crystal or white granules, odorless, nitrogen-containing 21%, soluble in water, not easy to moisture absorption, easy to store and apply, insoluble in ethanol and acetone, low toxicity, there is irritation. But wet rainy season has hygroscopicity, Ammonium Sulfate moisture absorption after solid block, so storage, also pay attention to ventilation and drying. Heated to 513 ℃ above completely decomposed into ammonia, nitrogen, sulphur dioxide and water. and alkali-like effect release ammonia. Barium sulfate precipitation is formed by reacting with the solution of chloride. It can also make the protein salting out.


Ammonium sulfate mainly acts on fertilizers, chemicals, agriculture, crops, rare earths, textiles, leather, medicine, soil, etc.

1, used as fertilizer, suitable for all kinds of soil and crops, Ammonium Sulfate can make the branches grow vigorously, improve fruit quality and yield, enhance crop resistance to disasters.

2, used in textile, leather, medicine and other aspects; acid dye dyeing aids, leather ash removal agent.

3, edible ammonium sulfate from industrial ammonium sulfate by adding distilled water dissolved, add arsenic removal agent and remove heavy metal agent for solution purification, filtration, Ammonium Sulfate evaporation concentration, cooling crystallization, centrifugal separation drying system. Used as a salt additive, a dough regulator, yeast nutrition.

4, used in biochemistry, salting out of the common salt, Ammonium Sulfate you can salting out the initial fermentation and other upstream products to isolate and purify protein.

5, Mining rare earth, mining ammonium sulfate as raw materials, the use of ion exchange form of rare earth elements in the ore exchange out, Ammonium Sulfate and then collect the leaching liquid simple filtration separation after drying into rare earth ore, each production of 1 tons of rare earth ore to take about 5 tons of ammonium sulfate.

Ammonium sulfate should be applied to the soil in order to facilitate the absorption of crops.

Ammonium sulfate is best used as an topdressing for crops. The amount of topdressing of ammonium sulfate should be determined according to different soil types. To protect the water and fertilizer poor performance of the soil, to be phased in, each dosage should not be too much; Ammonium Sulfate to protect the water and fertilizer performance of good soil, each dosage can be more appropriate.

Soil moisture also has a greater impact on fertilizer efficiency, especially in dryland, when applying ammonium sulfate must pay attention to timely watering. As for the paddy field for top dressing, it should be drained and dried, and should be paid attention to combined with the tiller. In addition, Ammonium Sulfate there are obvious differences in the application of ammonium sulfate in different crops, for example, when used in fruit trees, it can be applied to furrow, ring or acupoint application.

Matters needing attention in the use of ammonium sulfate for crop cultivation:

Note that the ammonium sulfate fertilizer can not be contacted or mixed with other alkaline fertilizers or alkaline substances to prevent the reduction of fertilizer efficiency.

Note that it is not advisable to apply ammonium sulfate to the same farmland for a long time, otherwise the soil will become acidic and harden. If the application is required, Ammonium Sulfate the appropriate amount of lime or organic fertilizer can be applied. However, it must be noted that ammonium sulfate and lime can not be mixed to prevent decomposition of ammonium sulfate, resulting in nitrogen loss. In general, the combination of the two is 3-5 days apart.

Note that three ammonium sulfate is not suitable for use in acidic soils.
