Pay attention to five taboos in the application of zinc fertilizer

China has a vast land and abundant resources, and has a rich type of climate, which is suitable for growing many different crops. When we are developing the planting industry, no matter what we plant, we need to do a good job in fertilizing. Fertilizers are generally based on organic fertilizers, nitrogen, phosphorus, potassium and other fertilizers. However, the application of micro-fertilizers such as zinc fertilizer should not be ignored. When we apply zinc fertilizer, there are five taboos that we should pay attention to. So what exactly is there? Let's take a look at it.

1. Avoid using it blindly

When we apply zinc fertilizer, we must target it purposefully. Zinc fertilizer is effective only for zinc-deficient soils or crops with high demand for zinc. Usually, if the content of zinc in the soil is less than 0.5mg per kilogram, then the application of zinc fertilizer can achieve effective fertilizer effect. On the contrary, if the zinc content is higher than 1mg per kilogram, then the effect will not be obvious. The crops that are more sensitive to zinc are food crops such as rice and corn, as well as vegetable crops such as onions and sugar beets.

2. Avoid excessive application

Zinc fertilizer is a kind of trace element fertilizer. Compared with basic elements such as nitrogen, phosphorus and potassium, crops generally do not have a great demand for zinc fertilizer. Overuse is not good, but it is also indispensable. If it is applied too much, it is easy to cause crop poisoning and affect crop growth. When applying zinc fertilizer, if it is used as base fertilizer, the amount of zinc should be controlled according to the content of zinc in the soil. When topdressing fertilizer is applied, it should be mixed with an appropriate amount of fine soil.

3. Avoid applying phosphate fertilizer at the same time

Zinc fertilizer is very important to the growth of crops, and it is an indispensable element for the growth of many crops. But when we apply it, we should pay attention to the reasonable matching of fertilizers. It should be noted that it should not be used together with phosphate fertilizer, because if zinc fertilizer and phosphate fertilizer are relaxed together, it is easy to form a zinc phosphate precipitate. This precipitate will not only reduce the efficiency of zinc fertilizer, but also affect the effect of phosphate fertilizer.

4. Avoid the simultaneous application of alkali fertilizer

In addition to phosphate fertilizer, zinc fertilizer can not be mixed with alkaline fertilizers such as lime and ammonia. Because zinc fertilizer contains an acidic ion, acidic ions and basic ions will react with each other, resulting in a decline in fertilizer efficiency. And also be careful not to apply with pesticides, because most pesticides are alkaline, whether it is zinc fertilizer or pesticide, its effect will be greatly reduced.

5. Avoid using it year after year

The effective time of zinc fertilizer after application is relatively long, and it generally does not have much effect in the same year. The fertilizer effect can not be brought into full play until the next year. Therefore, when we apply zinc fertilizer, we should be careful not to apply it year after year, and to understand the effective time of zinc fertilizer. Generally speaking, it should be applied every other year in order to ensure the full utilization of zinc fertilizer and improve the conversion rate of zinc fertilizer.

The above is a brief introduction to the five taboos in the application of zinc fertilizer. That's all for today's introduction. This article is for reference only. I hope it can help you all.
