5 common taboos in fertilizer use that agricultural production must avoid

   Agriculture is usually inseparable from the nourishment of fertilizers. Many farmers think fertilizer is a good product, so the more they apply, the better the crops look, but that is not actually the case. Improper use of fertilizers can cause great harm to the soil*. Only by applying fertilizers scientifically can the fertilizer use efficiency be higher and fertilizer damage be less likely. Today we will talk with everyone here about which aspects must be paid attention to when applying fertilizers.

   1. Acidity and alkalinity

   Fertilizers also have acidity and alkalinity. For example, ammonium bicarbonate and ammonium sulfate belong to the acidic type, while lime powder and plant ash belong to the alkaline type. Fertilizers with different characteristics certainly cannot be mixed and applied together. If they are mixed together, a neutralization reaction will occur, and the fertility will naturally decrease. Therefore, when applying fertilizers, they cannot be mixed at will; you must first understand their characteristics.

   2. Chlorine fertilizers

   Relatively speaking, there are more taboos in the application of chlorine fertilizers, because many crops cannot use chlorine fertilizers. Otherwise, not only will normal results fail to be achieved, but harm will also be caused to plant growth. For example, fruit trees, grapes, watermelons, and sweet potatoes all cannot use it. In addition, if the land belongs to saline-alkali soil, chlorine fertilizers also cannot be used.

   3. Nitrogen fertilizers

   Nitrogen fertilizer should be the most used among all fertilizers. One thing to note about this type of fertilizer is that after being spread, it takes several days to dissolve and be used, and it volatilizes very easily. It is generally recommended not to spread it directly on the soil surface, but to apply it by digging into the soil, so that waste can be avoided. In addition, do not irrigate right after application, otherwise it will also flow away along with the water. It is best to irrigate about three days after fertilizing.

   Also, for legume crops, too much nitrogen fertilizer cannot be used, mainly because there is a type of fungus at their roots that causes nitrogen fixation to be poorly absorbed. If too much is used, it will not only be wasteful, but also cause delayed maturity of the crops.

   4. Phosphate fertilizers

   Phosphate fertilizer is very easily fixed in the soil* and cannot be absorbed. Therefore, when applying phosphate fertilizer, it is recommended to first mix it with some manure and leave it together for a period of time before digging it in for fertilization. In addition, the cultivation of vegetables and fruits does not require too much phosphate fertilizer.

   5. Potassium fertilizers

   Plant growth requires potassium. Generally speaking, it needs to be applied when applying base fertilizer. In addition, potassium fertilizer needs to be increased when crops emerge. You cannot wait until the middle and late stages of growth to use it, as that would be too late.

   The above are the taboo requirements regarding fertilizer application compiled by the editor. When applying fertilizers, growers must pay attention to the above points. Scientific fertilization is more beneficial to crop growth.
