The Importance of Fertilizers

Fertilizers refer to a class of substances that provide one or more essential nutrients for plants, improve soil properties and improve soil fertility, and are one of the material bases for agricultural production. Fertilizers mainly include ammonium phosphate fertilizers, large-element water-soluble fertilizers, medium-element fertilizers, biological fertilizers, organic fertilizers, and multi-dimensional field energy-concentrated organic fertilizers. 

Fertilizers are essential for increasing crop yields. Nutrients necessary for higher plants include 16 kinds of nutrients including carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, boron, manganese, copper, zinc, molybdenum, and chlorine. element. These 16 essential nutrients can be divided into macronutrients, medium, and micronutrients because of their different contents in crops. Macronutrients account for about a few thousandths to tens of percent of dry matter weight in crops, such as carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, etc.; medium and micronutrients account for about 100% of dry matter weight in crops Several thousandths to several hundred thousandths, such as calcium, magnesium, sulfur, iron, boron, manganese, copper, zinc, molybdenum and chlorine. The lack of any element will affect the normal growth and development of crops. For example, nitrogen deficiency will lead to short and thin plants, and leaves that are abnormally green such as yellow-green and yellow-orange. When there is a severe nitrogen deficiency, the crops will senesce and mature prematurely, and the yield will be significant. Only by increasing nitrogen fertilizer can reduce its harm. 

How to Store

1. Anti-moisture and deterioration: fertilizers that are easy to absorb moisture should be stored in a dry and cool place, especially when ammonium bicarbonate is stored, the packaging should be tightly sealed to avoid contact with air.

2. Fire and sun protection: Nitrogen fertilizers should be stored away from the sun, no fireworks, and should not be stacked with diesel, kerosene, firewood, and other items. 

3. Anti-volatile loss: Ammonia and ammonium bicarbonate are very easy to lose by volatilization, so they should be sealed during storage. Nitrogen fertilizers and superphosphate are strictly prohibited to be mixed with alkaline substances (lime, plant ash, etc.) to prevent the volatilization loss of nitrogen fertilizers and reduce the fertilizer efficiency of phosphate fertilizers. 

4. Anti-corrosion and poisoning: superphosphate is corrosive and prevents contact with skin and metal utensils; ammonia water is highly corrosive to copper and iron and should be stored in ceramic, plastic, and wooden containers. In addition, chemical fertilizers should not be stacked with seeds, and seeds should not be bagged with chemical fertilizers, so as not to affect the germination of seeds.
