Types of fertilizers

Including ammonium phosphate fertilizers, a large number of element water-soluble fertilizers, medium element fertilizers, biological fertilizers, organic fertilizers and multi-dimensional field energy concentrated organic fertilizers.

Attention should be paid to the storage of fertilizers:

1. Prevent regressing moisture deterioration

For example, ammonium bicarbonate is easy to absorb moisture, resulting in nitrogen volatilization loss; ammonium nitrate has strong hygroscopicity, easy caking and hydrolysis; lime nitrogen and calcium superphosphate are easy to agglomerate after moisture absorption, affecting the application effect. Therefore, these fertilizers should be stored in a dry and cool place, especially when ammonium bicarbonate is stored, the packaging should be sealed firmly to avoid contact with air.

two。 Fire protection from the sun

After the nitrogen fertilizer is exposed to the sun or high humidity, the volatilization loss of nitrogen will be accelerated; ammonium nitrate will decompose oxygen at high temperature, and flammable materials will burn. Do not hit the caked ones with a hammer to prevent explosion. Nitrogen fertilizer storage should avoid the sun, strictly prohibit fireworks, do not stack with diesel oil, kerosene, firewood and other items.

3. Anti-volatilization loss

Ammonia and ammonium bicarbonate are easy to volatilize and should be sealed during storage. Nitrogen fertilizer and calcium superphosphate are forbidden to be mixed with alkaline substances (lime, plant ash, etc.) to prevent the volatilization loss of nitrogen fertilizer and reduce the fertilizer efficiency of phosphate fertilizer.

4. Anti-corrosion and toxicity

Calcium superphosphate is corrosive to prevent contact with skin and metal utensils; ammonia is strongly 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 do not use chemical fertilizers to bag seeds so as not to affect seed germination.

At present, there are many kinds of fertilizers on the market, and there are also many producers. When buying, you should pay attention to distinguish the true from the false, and do not be misled by the exaggerated efficacy.
