What are the common types of compound fertilizer and what are their effects?

Compound fertilizer is often used in agricultural production, and has always been key to high crop yields. To a certain extent, it can promote the growth of vegetables or fruit and achieve high yields, and compound fertilizer has relatively stable properties. So what are the common types of compound fertilizer? What are their effects? Let's find out together below!

1. Ammonium phosphate

Ammonium phosphate has relatively stable properties and is suitable for various soils and crops. When applied as a base fertilizer, it should be applied together with nitrogen fertilizer, and it must not be placed too close to the roots. Special attention should be paid to avoiding mixing it with alkaline fertilizers, because they will undergo a chemical reaction and thus lose their fertilizer efficiency.

2. Nitrophosphate

Nitrophosphate has strong hygroscopicity and easily decomposes when exposed to alkali. Its components are ammonium nitrate, calcium nitrate, ammonium phosphate and dicalcium phosphate. It is not recommended for use in paddy fields and leguminous crops. It is generally used as a base fertilizer and topdressing. As a base fertilizer, it should be applied deeply in a concentrated manner, and the fertilizer efficiency of ammonium phosphate fertilizer is greater than that of nitrophosphate fertilizer. When planting crops such as rice, ammonium phosphate fertilizer can be selected.

3. Potassium nitrate

Potassium nitrate is easily soluble in water and is flammable and explosive. It is mainly used for seed soaking or foliar spraying, and is very suitable for potassium-loving crops, such as tobacco and grapes.

4. Potassium dihydrogen phosphate

Potassium dihydrogen phosphate is easily soluble in water and is often used for foliar spraying and seed soaking. It has a very wide adaptability, plays a key role in increasing fruit set and strengthening seedlings, and can also improve crop resistance. It can also be used alone during the flowering period and fruit formation period of crops. If it is used for drip irrigation, sprinkler irrigation or flushing application, just pay attention to the concentration, but it must not be mixed with alkaline pesticides.

In summary, that is the introduction to the common types of compound fertilizer. If everyone wants to use compound fertilizer to increase crop yields, then scientific fertilization work must be done well. Avoid various kinds of fertilizer damage.
