Nitrate Fertilizer

Ammonium sulfate, which contains 20% -21% of nitrogen and 24% of sulfur, is a necessary nutrient element for plants. It is an odorless colorless crystalline or white granular inorganic substance insoluble in ethanol and acetone. Ammonium sulfate is mainly used as fertilizer.

Agricultural ammonium chloride is mainly used to make nitrogen fertilizer. Ammonium chloride is a nitrogen-containing chemical fertilizer with a nitrogen content of 24% to 26% . In agriculture, ammonium chloride is widely used as a nitrogen fertilizer because it contains the nitrogen needed by plants to grow. Nitrogen is one of the key nutrients for plant growth, which plays an important role in chlorophyll synthesis, photosynthesis and overall growth and development.

Urea is a kind of high concentration nitrogen fertilizer, which is a kind of neutral quick-acting fertilizer, and can also be used to produce many kinds of compound fertilizers. No harmful substances remain in the soil, long-term application of no adverse effects. Urea is used as a base fertilizer, or as a top dressing, and sometimes as a seed fertilizer also. Urea before conversion is molecular state, it can not be adsorbed by soil, it should prevent loss with water. When urea is applied to the soil, a small amount of the urea is dissolved in the soil solution in molecular form and adsorbed by the soil through hydrogen bonding. 

There are two specifications of granular urea, with small particles having a diameter of about 1.5 millimeters and large particles having a diameter of about 2.0-4.75 millimeters. Please let us know which specification you require.

Controlled release urea fertilizer is a type of urea fertilizer that maintains a longer fertilizer efficiency due to slow release of effective nitrogen caused by changes in chemical composition or surface coating with semi permeable or impermeable substances. The advantage is that after one application, it can meet the nutrient needs of crops for a period of time to adapt to their growth patterns. The main varieties include formaldehyde fertilizers, sulfur coated urea, etc.
