What fertilizer is good for wheat base fertilizer (the best formula for wheat compound fertilizer base fertilizer)

What kind of fertilizer does wheat need?

What kind of fertilizer to use for wheat base fertilizer depends on the nutrients needed for wheat growth. As we all know, the main nutrients needed for wheat growth are nitrogen, phosphorus and potassium .

Studies have shown that to produce 100 kilograms of wheat, about 3 kilograms of nitrogen, 1-1.5 kilograms of phosphorus pentoxide, and 2-4 kilograms of potassium oxide are needed from the soil. The ratio of nitrogen, phosphorus, and potassium required is approximately 3:1:3 .

Knowing this, it is not difficult to find the answer to what kind of fertilizer to use for wheat base fertilizer. That is, wheat base fertilizer must be rich in nitrogen, phosphorus and potassium .

Classification of fertilizers for wheat fertilization

Fertilizer products mainly include nitrogen fertilizer, phosphate fertilizer, potash fertilizer and compound fertilizer.

The main types of nitrogen fertilizers include ammonium carbonate, urea, etc. The main types of phosphate fertilizers include calcium magnesium phosphate, superphosphate, nitrophosphate, monoammonium phosphate, diammonium phosphate, etc. The main types of potash fertilizers include potassium chloride, potassium sulfate, etc.

What farmers usually refer to as compound fertilizer is triple compound fertilizer, that is, compound fertilizer that contains the three nutrient elements of nitrogen, phosphorus and potassium at the same time.

In fact, monoammonium phosphate and diammonium phosphate are also a kind of compound fertilizer. Because monoammonium phosphate and diammonium phosphate mainly contain two elements, nitrogen and phosphorus, they are called binary compound fertilizers.

The ratio of wheat base fertilizer should be reasonable

After understanding the above content, you can know that when wheat is sown, you can choose triple compound fertilizer as the base fertilizer, or you can use diammonium phosphate and potassium fertilizers together . Of course, you can also use urea, phosphate fertilizer and potassium fertilizer separately as base fertilizer, or you can use diammonium phosphate and potassium fertilizers together.

From the perspective of economy and fertilizer efficiency, it is most economical and practical to use triple compound fertilizer as wheat base fertilizer. However, if conditions permit, it is most scientific to use formula fertilizer, which is to supplement what is lacking, with better effect and more cost-saving.

How many kilograms of wheat base fertilizer and compound fertilizer are needed per mu

Based on the fertilizer requirements of wheat, soil fertility, per-acre yield, etc., we can roughly calculate how much fertilizer is needed per acre of land.

If using triple compound fertilizer, the nitrogen, phosphorus and potassium (N-P2O5-K2O) content of 16-16-10, 15-18-7, or 16-16-10 can all be used.

Choose according to different soil fertility. Of course, if there is a 3 15 (15-15-15) formula, it is also very good .

If the wheat yield per mu of the land is 500-600 kg, the above-mentioned triple compound fertilizer can be used as base fertilizer, and the required amount per mu is 50 kg.

If urea, phosphate fertilizer and potassium fertilizer are used as base fertilizers respectively, or diammonium phosphate and potassium fertilizers are used as base fertilizers, the specific dosage should be determined after converting the proportions according to the fertilizer content.

According to years of experience, a bag of triple compound fertilizer containing 3:15 is enough for wheat base fertilizer, which is about 50 kilograms per acre of land.

What fertilizer is good for wheat topdressing?

Of course, for wheat growth, it is unscientific to apply enough base fertilizer at one time. In addition to applying enough base fertilizer, top dressing should also be carried out.

Topdressing should be mainly quick-acting nitrogen fertilizer, and urea is the most commonly used . From the wheat rooting stage to the jointing stage, 15-20 kg of urea can be applied per mu in combination with irrigation.
