How much fertilizer is needed to grow corn per acre?

As the saying goes, the success of crops depends on fertilizer. Fertilization is essential for growing corn, so how much fertilizer should be applied per acre of land?

It's hard to say. The amount of fertilizer applied will definitely be different depending on the method of fertilization, the time of fertilization, the type of fertilizer, the corn variety, the soil fertility, etc. Can you tell me an accurate number? Those who can tell me an accurate number must be experts, but I am not, so I can't tell you an accurate number.

I know that, as far as I am concerned, we basically apply fertilizer all at once, that is , we apply seed fertilizer and fertilizer at the same time. Some people apply 100 kilograms of compound fertilizer per acre, some apply 150 kilograms, and some apply 60-70 kilograms as base fertilizer, and then apply 50-80 kilograms or even 100 kilograms of special fertilizer for corn per acre .

We can say that each family has its own sutra, and each family recites their own sutra, so the sutras are different.

But one thing is certain, that is, in the same plot of land, the same variety, sowing at the same time, and under the same management, the yield of 100 kilograms of compound fertilizer per mu of land will be lower than that of 150 kilograms. How much lower? I am not sure.

However, one thing is certain, that is, the current method of fertilization will definitely cause waste, and a lot of it. Don't believe it? Corn lodging is related to excessive fertilization.

However, after the corn is harvested, wheat is basically sown. Except for the fertilizer that is lost, evaporated, fixed, etc., the rest will not be wasted and will be absorbed and utilized again by the wheat.

In fact, the yield of corn cannot be achieved by fertilizer alone, but also depends on light, temperature, water, variety, etc.

If you want a high corn yield without wasting fertilizer, there is only one way, which is to test the soil and apply fertilizer according to the formula. It is absolutely reliable and can basically be applied according to demand with less waste.

However, can you test the soil and formulate fertilizers?
