I don't know if you have ever encountered this kind of situation. Everyone knows that the fertilizer is not sold, and the purchase of a bag of fertilizer can not be used. After a while, it is found that the fertilizer can no longer be used. Therefore, the fertilizer that has been opened must be properly kept, and a small number of methods for rational storage of fertilizers are prepared for your reference.

(1) Prevent mixing. When chemical fertilizers are mixed together, it is easy to deteriorate physical and chemical properties. If the calcium phosphate encounters ammonium nitrate, it will increase the hygroscopicity, resulting in inconvenient application.

(2) The anti-identification name is not true. Some farmers use compound fertilizer bags to pack urea, some use urea bags to mix compound fertilizer or ammonium sulfate, and some use special fertilizer in imported compound fertilizer bags, so that it is easy to make mistakes during use.

(3) Anti-break bag packaging. For example, the nitrate nitrogen fertilizer has strong hygroscopicity, and will be turned into a slurry after being absorbed, even in a liquid, and should be sealed and stored, generally stored in an altar or a package container, and tightly capped.

(4) Fire prevention. Specially applied nitrate, such as ammonium nitrate or potassium nitrate, will decompose oxygen when exposed to high temperature (200 ° C), and will burn or explode if exposed to fire.

(5) Anti-corrosion. Superphosphate contains free acid, and ammonium bicarbonate is alkaline. Do not contact such metal fertilizers or scales to avoid corrosion.

(6) Anti-fertilizer mixed with seeds and food. In particular, the strong volatile ammonium bicarbonate, ammonia and seed mixed will affect the germination, should be fully noted.

Steroids

"Steroids are a general term for a large group of derivatives widely distributed in the biological world, which can also be called steroidal or steroidal compounds. Steroid hormones are mainly synthesized and secreted by various parts of the body, and a small part can be synthesized artificially. They play an important auxiliary role in the functional activities of organs, tissues and cells of the body. Steroid hormones mainly include adrenal cortical hormones secreted by the adrenal cortex and gonadal secretion of sex hormones, when taking a large number of steroid hormones, will produce swollen face, nausea and other side effects
