How to avoid antagonism between fertilizers

Antagonism is often encountered in the process of fertilization, commonly known as element fighting, which is often common in major producing areas, which is due to chemical reactions caused by improper fertilization, resulting in the formation of insoluble substances, resulting in crops can not absorb. So what can we do to avoid elemental antagonism? Come and have a look with the editor.

First, the cause of element antagonism

1. Excessive fertilization

Excessive fertilization during fertilization is very likely to produce antagonism, such as the common partial application of potassium fertilizer, will cause concentration barriers, resulting in increased risk of crop infection of diseases and insect pests, resulting in antagonistic effects of elements such as calcium, magnesium and boron in soil and plants. If the circumstances are more serious, there will be other problems, or even a serious reduction in production. For example, partial application of nitrogen fertilizer will also cause potassium deficiency; partial application of phosphorus fertilizer will inhibit the absorption of nitrogen by crops, resulting in nitrogen deficiency. Therefore, we should have a full understanding of the nutrients that crops need to maintain before fertilization to avoid this situation.

2. Synchronous fertilization

Simultaneous fertilization can also cause antagonism, for example, phosphate fertilizer and zinc fertilizer can not be applied at the same time, because they will produce element reaction, form insoluble precipitation and reduce the utilization rate of elements.

3. Soil pH

The acidity and alkalinity of soil may also bring. Acidic soil can antagonize the absorption of cations, while alkaline soil can also antagonize the absorption of anions.

Second, how to avoid antagonism

1. Understand the properties of fertilizer

Before fertilizing and supplementing nutrients, be sure to have a clear idea of the elements needed by crops, and then understand whether there will be antagonism between them, whether it is caused by partial application of nitrogen fertilizer or simultaneous fertilization, which should be understood clearly. It is helpful for us to fertilize correctly.

2. Farm manure must be mature

Farm manure must be fully mature before application, which can not only supplement sufficient elements, but also increase the content of soil organic matter and effectively improve soil structure. If it is immature farm manure, it will continue to ferment and mature after application, causing root system burns and carrying germs and eggs.

3. Use organic fertilizer

Organic fertilizer contains not only large and medium trace elements needed for plant growth, but also rich organic nutrients, which can effectively improve soil properties and biological characteristics, enhance soil water and fertilizer conservation, and create suitable soil for crop growth and development. In addition, the rational combined application of organic fertilizer and chemical fertilizer can complement and promote each other, which is beneficial to crop absorption, improve fertilizer use efficiency, buffer or reduce the antagonism between nutrients.

4. Fertilization according to soil properties.

In potassium-deficient plots, nitrogen and potash should be matched reasonably, but potash should not be used at one time, because potassium ions can also antagonize the similarity of calcium, magnesium and ammonium.
