Fertilizer always doesn't work after using it. Did you buy fake fertilizer again?

Many farmers are apt to fall into a misunderstanding when using chemical fertilizer, that is, to judge whether it is a "good fertilizer" by the speed of effect, especially after seeing that other people's crops use fertilizer immediately, but their own has not moved for a while. They will be more suspicious that they have bought fake fertilizers. in fact, the effective period and duration of different fertilizers are different, and the quality can not be judged directly by the speed of fertilizer effect.

Does a quick fertilizer have to be a good fertilizer?

Many unscrupulous businesses take advantage of farmers' eagerness to see results by adding hormones to fertilizers, and crops using this kind of fertilizers will achieve the effects of long stems and bigger fruits within a short period of time, but after using them for a period of time, there are often phenomena such as yellowing of old leaves and premature senescence of fruits, so these "quick-acting fertilizers" only create an immediate illusion to farmers and do little good to crop growth.

How long is the effective period of all kinds of fertilizers?

After ammonium bicarbonate is applied to the soil, it can be effective on the same day, and the fertilizer effect period is about half a month.

Ammonium chloride can be effective 3 days after application, the fertilizer effect can last for 25 days, and will be de-fertilized in the later stage.

Urea takes effect in a week, and the fertilizer effect can last for one and a half months.

The compound fertilizer can take effect in 10 days and last for 3 months.

It takes about 1 month for biological fertilizer to be effective, but it lasts for a long time, up to 6-8 months.

After fertilizers such as biological bacteria fertilizer are applied into the soil, the bacteria need a certain amount of time to restrain or kill pathogenic bacteria and improve the soil structure, so the effective period will be slower than that of ordinary fertilizers, but it will have a long-term effect on the health of the soil in the later stage.

Therefore, crop fertilization is not achieved overnight, but requires a reasonable proportion, combined with each other, long-term supply, in order to achieve a real high yield.
