Time for various fertilisers to work

How long does it take for fertiliser to take effect when applied to the ground

Fertiliser needs to be available for a long time and is applied in proportion to the physiological characteristics of the crop at each period, there is no need to blindly pursue sex. Nowadays, many unscrupulous manufacturers have figured out the psychology of farmers, adding a lot of or adding a lot of poor quality nitrogen fertilizers to the fertilizers they make, while the marking instructions say that the ratio of nitrogen, phosphorus and potassium is very good, or contains high nitrogen and high potassium, etc. The effect is not necessarily good after application by farmers.

Fast fertilisers, after application, often cause problems such as vigorous crop growth, poor bud differentiation and early failure, which in turn reduces overall yield. Therefore, I would like to remind farmers that they must choose rationally when buying fertilizers, and that fast fertilizers are not necessarily good after application.

Fertilizer products fertilizer efficiency period

Ammonium carbon:, the same day, fertilizer effectiveness period of 15 days.

Ammonium chloride:, fertilizer effectiveness period of 25 days, late off fertilizer.

Urea: seven days, fertiliser efficiency period 45 days.

Compound fertilizer: ten days, with a fertilization period of 90 days.

biological fertilizers: generally about one month, the effect is not yet obvious in crops with long growth cycles, but the fertilizing effect lasts for 6 to 8 months.

Note: Fertilisers need to be available for a long time and should be applied in proportion to the physiological characteristics of the crop at each period, there is no need to pursue sex blindly.
