The best use method of compound fertilizer

Compound fertilizer is a kind of fertilizer that many growers are very familiar with. In planting and production, compound fertilizer is the key to ensure the normal growth of crops and increase the yield. Compound fertilizer includes many nutrient elements, such as a large number of common elements such as nitrogen, phosphorus and potassium. So when we use compound fertilizer, how to use it? The editor brings you the best way to use compound fertilizer today. Let's take a look at it.

1. Used as base fertilizer

The fertilizer effect of compound fertilizer lasts for a very long time, so many people will choose compound fertilizer as base fertilizer. Especially when growing vegetables that grow in a short period of time. It is mainly because many crops are sensitive to the changes of nutrients in the early growth stage, and the compound fertilizer includes a lot of nutrients such as nitrogen, phosphorus and potassium. And in the controlled-release compound fertilizer, it is generally based on coating. Compared with simple chemical fertilizer, its decomposition speed is not fast, the loss of nutrition is not much, and it has a very high utilization rate, so it is very suitable to be used as base fertilizer.

2. Used as topdressing

Compound fertilizer is also used by many people when topdressing, mainly because the base fertilizer is not mixed with compound fertilizer. Generally speaking, when crops break the soil and emerge from seedlings, ditching and manuring is carried out, and then the soil is covered after fertilization. However, we must pay attention to control the amount of fertilizer to avoid waste. And in general, compound fertilizer is not recommended to be used as topdressing. Because topdressing can easily lead to waste of elements such as phosphorus and potassium, because if the compound fertilizer powder is applied on the soil surface, its fertilizer effect is not obvious, and the utilization rate is far lower than that of the base fertilizer.

3. Used as seed fertilizer

Compound fertilizer can also be used as a kind of fertilizer. When as a kind of fertilizer, we should pay attention not to mix seeds, but also pay attention to control the concentration, and remember that the concentration is not too high. If the compound fertilizer with high concentration is used as seed fertilizer, it is very easy to cause the seeds to be burnt out and the seedlings to burn. Therefore, when we use it as a kind of fertilizer, we should pay attention to separating the seed from the fertilizer. When sowing, first apply the seed hole, and then apply the compound fertilizer, the distance between the compound fertilizer and the seed should be kept at about 6-8 cm, to avoid fertilizer damage too close.

4. Deep application of covering soil

When applying compound fertilizer, because the nitrogen element is easily washed away by Rain Water, and the volatilization rate is high, and the phosphorus and potassium element is also very easy to be fixed. And if it is applied to the surface, it is also very disadvantageous to the absorption of crop roots. In addition, if the soil is dry, the fertilizer dissolves very slowly, resulting in a decline in fertilizer efficiency. Therefore, when we apply compound fertilizer, we should try not to spread fertilizer on the surface, but mainly cover the soil with deep application.

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