Fertilizer Storage to do "Six Prevention"

In the hot and rainy season, fertilizer should be mainly stored in warehouses. The warehouse should be ventilated and cooled, but also to prevent rain and moisture. Fertilizer in the warehouse storage methods are large piles of storage and bag storage.

For more hygroscopic nitrogen fertilizer varieties such as ammonium, whether large piles of bulk storage or bagged storage, in order to avoid caking, should control the height of the bulk pile and bagged pile, such as 25 to 40 kg of large bags stored in a pile of 20 bags as a moderate height.

If you choose cargo shed storage, the pile location should be chosen in a higher terrain, flat ground, not waterlogged place, under the reed mat or plastic film. After the fertilizer is stacked neatly, the top should be covered with plastic film, while erecting the roof of the shed, covered with thatch and other measures to prevent rain.

Here is a special reminder that fertilizer storage to do "six prevention".

A prevent volatilization. Ammonia, ammonium bicarbonate is very volatile, so the storage should be sealed. There are nitrogen fertilizer, calcium phosphate is strictly prohibited with lime, grass ash and other alkaline substances mixed pile to prevent chemical reactions, resulting in nitrogen fertilizer volatilization and reduce the effectiveness of phosphate fertilizer.

Two anti-humidity. Ammonium, lime nitrogen and calcium superphosphate absorb moisture and easy to caking, affecting the application effect. There is also ammonium bicarbonate moisture absorption, nitrogen volatile, to be sealed firmly to avoid contact with the air. Therefore, these fertilizers should be stored in a dry, cool place.

Three anti-corrosion. Calcium superphosphate is corrosive, should be prevented from contact with the skin, metal appliances; ammonia is strongly corrosive to copper, iron, should be stored in ceramic, plastic, wooden containers. In addition, fertilizer can not be stacked with the seeds, and do not use fertilizer bags of seeds, so as not to affect the germination of seeds.

Four anti-high temperature. Nitrogen fertilizer by the sun, the loss of nitrogen volatilization will accelerate; ammonium at high temperatures will decompose oxygen, these can cause fertilizer failure.

Five fire. Ammonium, potassium and other combustible, storage can not and flammable materials such as kerosene, gasoline, straw, wood chips, etc. stacked together to avoid causing a fire.

Six anti-metal. Ammonium, potassium, etc. If mixed with copper, iron and other metal powder, once the friction impact, it will cause accidents. So these fertilizers caking hardened, do not use metal objects to pound, to crush with heavy objects.
