How to choose compound fertilizer

Compound fertilizer is widely used in planting and production. The nutrients of compound fertilizer are sufficient and comprehensive, and the content is also very high. It can meet the nutrition needed for the growth of most crops, and when we apply compound fertilizer, we should do a good job in the selection of compound fertilizer according to the actual situation. So how on earth should we choose compound fertilizer? Today, the editor will give you a brief introduction. Let's take a look at it.

1. Consider the soil quality

When choosing compound fertilizer, the first thing we should consider is the quality of the soil. The varieties of compound fertilizer suitable for application will be different according to the different soil properties. For example, for some alkaline soils, if the content of organic matter is low and lack of available nitrogen and phosphorus, then when applying compound fertilizer, we should mainly use acid nitrogen, phosphorus and potassium compound fertilizer. Such as monoammonium phosphate or humic acid compound fertilizer. On the contrary, if it is red clay or acidic loam, then the compound fertilizer should be chemically alkaline, such as diammonium phosphate and so on.

2. Crop varieties

There are also some differences in the choice of compound fertilizer among crop varieties. When planting field crops, compound fertilizer should be based on nitrogen and phosphorus fertilizer, while if it is a wheat field or a field with higher yield, then it should be mainly ternary compound fertilizer. Then for some rice, millet and other crops that are more densely planted, powdered compound fertilizer should be applied. On the contrary, for sparsely planted crops, the variety of compound fertilizer should be granular. In addition, there are legume crops, rhizome crops and so on, and the suitable varieties of compound fertilizer are different.

3. Mixed with simple fertilizer

The nutrient elements in compound fertilizer are fixed, so when applying compound fertilizer, if you want to be able to increase production normally. Then we also need to cooperate with an appropriate amount of elemental fertilizer to meet the needs of different nutrients in different growth stages of crops. For example, when growing crops such as rice and wheat, there is a greater demand for nitrogen during the growing period. if the compound fertilizer is mainly composed of diammonium phosphate and other nitrogen, it is necessary to calculate the amount of phosphorus and then supplement the corresponding elemental nitrogen fertilizer.

3. Application method

The application method of compound fertilizer will also have a certain influence on its choice. If it is applied as a base fertilizer, then the compound fertilizer should be mainly granular, the harder the better, which can effectively improve the fertilizer efficiency. If it is applied deeply, then it should be mainly compound fertilizer containing ammonium nitrogen, which can improve the soil adsorption rate and avoid fertilizer wetting, and can be applied in most soil types and crops. The compound fertilizer of nitrate nitrogen should be chosen for dryland crops. If it is used as a kind of fertilizer, then we should pay attention to the content of nitrogen elements, not too high, to avoid burning seeds and seedlings.

The above is a brief introduction to how to choose compound fertilizer. That's all for today's introduction. This article is for reference only. I hope it can help you all.
