The period of use of humic acid fertilizer and matters needing attention

The use of chemical fertilizer is indispensable in the process of crop planting, and now more and more farmers are using humic acid fertilizer, but many farmers feel that there is no effect after using it, in fact, they are using the wrong time. So what is the best use of humic acid fertilizer? What should I pay attention to? Come and have a look with the editor.

1. Critical period of humic acid fertilizer

1. Imbalance of soil acidity and alkalinity

In recent years, due to the abuse of chemical fertilizer, a lot of soil has been polluted, soil acidification is becoming more and more serious, and once the soil is acidified, the root system of crops will be poisoned, affecting the root system to absorb nutrients. At this time, we can use humic acid to calculate fertilizer and supplement elements such as calcium, magnesium, iron and zinc for the root system in time, so as to achieve the purpose of regulating soil acid-base balance.

2. Soil drought and waterlogging

In addition to nutrients, water is also very important for the growth and development of crops. If it is high temperature and rainy weather in summer, the soil is very prone to drought or waterlogging. At this time, the root system of crops is relatively fragile, and their growth will be seriously affected. At this time, if humic acid fertilizer is used, it can effectively reduce the water loss of crops and improve their drought resistance.

II. Points for attention in use

1. Pay attention to the concentration

Humic acid fertilizer and auxin play are somewhat similar, in the process of use, we should pay attention to the concentration of fertilizer, if the concentration is too high or too low, then the effect on crops is not very obvious, if serious, it will also affect the growth and development of crops.

2. Pay attention to the use temperature

When using humic acid fertilizer, we must pay attention to the temperature. Generally, the suitable temperature takes 18 hours to take effect. If humic acid fertilizer is used at low temperature, the effect is very slow, which is easy to cause fertilizer waste and increase planting cost. If the high temperature is used, it may cause fertilizer damage and seriously affect the yield of crops.

3. Pay attention to collocation.

Humic acid fertilizer as base fertilizer and seed fertilizer is better than topdressing, concentrated application is better than sprinkling, deep application is better than shallow application, but we should pay attention to it can not completely replace inorganic fertilizer and farm fertilizer, must be used with chemical fertilizer and organic fertilizer.

4. Pay attention to the application effect

The effect of humic acid fertilizer will vary from crop to crop, which will be better in cabbage and radish, but worse in tuber crops and even worse in cereal crops.
