Description
Ammonium sulfate fertilizer contains 21% nitrogen in the form of ammonium ions and 24% sulfur in the form of sulfate. Among the uses of this fertilizer in the agricultural sector, he pointed out that it is used to correct and reduce the pH of alkaline soils, as well as providing nitrogen and sulfur needed for the growth and development of plants and improving the quality of agricultural products.
Advantages
Faster absorption of nitrogen by the plant due to the presence of ammonium
Soil amendment and pH reduction of alkaline and calcareous soils
Wastage and washing is less expensive than urea fertilizer
Can be used as a solution, spraying and chalkod
Increase the growth and production rate of plants and products
Increasing the effect of phosphate fertilizer in simultaneous use
Time and method of consumption
In agricultural lands, 300 to 400 kg per hectare before planting
15 grams per plant in greenhouses and 25 grams per square meter in gardens.
In gardens, one kilogram per tree in early spring
Sulfur coated urea S.C.U
Urea fertilizer is one of those fertilizers that are soluble in water. Generally, water-soluble fertilizers are covered with a layer of sulfur so that the materials in the fertilizer are gradually released and absorbed by the soil and plants. Among this category of fertilizers, urea fertilizer with sulfur coating is one of the most common types.
In sulfur coated urea fertilizer, hot urea is coated with molten sulfur and the sulfur surface is covered with a layer of polyethylene or micro crystal wax.
Urea fertilizer with sulfur coating has a very good performance in the soil, and since urea fertilizer alone has low efficiency and leads to nitrate pollution in the soil and underground resources, it is recommended to use urea fertilizer with sulfur coating.
Normally, urea fertilizer with sulfur coating contains 30 to 40% nitrogen and between 15 to 20% sulfur. By using urea fertilizer with sulfur coating, not only the nitrogen needed by the soil is provided, but the sulfur layer in this fertilizer prevents the leaching of nitrogen to a great extent.
Advantages
Fertility of the soil and increase in yield are other advantages of using urea fertilizer with sulfur coating.
Urea fertilizer with sulfur coating increases the ability to absorb micronutrients.
Nitrate pollution in soil and underground water is reduced.
The sulfur coating in this fertilizer prevents the plant from burning due to high consumption of urea.
The sulfur coating in this fertilizer increases the activity level of bacteria and beneficial soil microbes.
