What is the best fertilizer for wheat?

Wheat fertilization time

Wheat should be fertilized in early March in spring. At this time, it is necessary to apply fertilizer according to the development of the wheat seedlings, apply fertilizer according to the local conditions, apply fertilizer according to the seedlings, apply foliar fertilizer, and apply fertilizer according to the climate.

The first topdressing of wheat is for the winter wheat seedlings in the greening period after the spring. A nitrogen fertilizer is applied when the wheat grows up. One bag of ammonium urea is equivalent to 100 kilograms per mu. The trench fertilization method is adopted, and the soil is covered and combined with plowing and watering. The second topdressing is when the wheat grows to the second leaf, and 24 kilograms of urea is applied per mu.

What fertilizer to use for wheat

1. Organic fertilizers can be applied when planting wheat, mainly including compost, fermented manure, manure, biogas fertilizer, green manure, crop straw, cake fertilizer, mud fertilizer, etc. Organic fertilizers are rich in various nutrients, release nutrients slowly, and have long fertilizer effects. They are mainly used as base fertilizers and are applied in holes or strips during sowing.

2. Wheat absorbs and utilizes nitrogen fertilizer mainly in the form of ammonium nitrogen, so ammonium chloride, ammonium bicarbonate, urea, ammonium sulfate, ammonium nitrate, etc. can be used in wheat production. Urea, long-acting carbon ammonia, and sulfuric acid are better as base fertilizers, and quick-acting ammonium bicarbonate is better as topdressing.

Wheat fertilization method

1. When fertilizing wheat, organic fertilizers and inorganic fertilizers need to be used together. The short-term benefits of increased production are good, and the long-term benefits far exceed the increased costs. The fertilizer efficiency obtained from land fertilization is improved. No matter what kind of organic fertilizer is used, it must be used in combination with inorganic fertilizers to improve fertilizer efficiency.

2. Under normal circumstances, the ratio of nitrogen, phosphorus and potassium should be maintained at 1:0.7:0.4. Not all nitrogen fertilizers should be applied at the bottom of the field. For medium-yield fields, half of the fertilizers should be applied at the bottom of the field and half should be applied as topdressing. For high-yield fields, 40% should be applied at the bottom of the field and 60% should be applied as topdressing. All other fertilizers should be applied at the bottom of the field.

3. Foliar spraying is mainly used in the later stage of wheat growth. It can be sprayed on the leaves of wheat. The fertilizer is mainly composed of 0.2% potassium dihydrogen phosphate and a corresponding proportion of pesticides.

Precautions for wheat fertilization

When fertilizing wheat in some areas, the amount of phosphorus fertilizer applied can be appropriately reduced, because the phosphorus content in the soil has been at a high level due to the continuous application of more phosphorus fertilizers for many years.
