What is the function of green manure?

As the name implies, green manure is a kind of fertilizer made from green plants. The nutrition of green manure is very comprehensive, so now many people will choose to plant some green manure when planting crops. Green manure is very beneficial to the growth of crops, and it also plays a great role in improving the soil environment. So what is the specific function of green manure? The following editor will give you a brief introduction, let's have a look!

1. Improve the soil

When we apply chemical fertilizer to crops, no matter how we apply chemical fertilizer, we need to match it with some limited elements. Basically, there is no guarantee to meet the growth needs of crops. Especially for the demand for soil fertilizer, and green manure can effectively solve this problem. Green manure is rich in organic matter, which can provide a large amount of organic matter for cultivated land, so as to improve soil and improve soil quality. Moreover, it can also reduce the application of chemical fertilizers and pesticides and increase soil fertility, thus promoting the growth of crops.

2. Provide nutrients

Providing nutrients is one of the most important functions of green manure. Green manure has the function of activating and absorbing potassium, while some legume green manure also has the role of nitrogen fixation. And green manure can produce a lot of organic matter when growing, so it can provide a lot of nutrients for the growth of crops, so as to improve the yield of crops. In continuous cropping, if interplanting some green manure, it can effectively reduce the continuous cropping obstacles produced by some crops, thus reducing the occurrence of diseases and insect pests. Especially for some areas with serious obstacles to long-term planting of a crop and continuous cropping, the effect of interplanting green manure is very good.

3. Improve the environment

When planting crops, proper planting of green manure can effectively reduce soil erosion in the planting area. To enhance the resistance of the ecological environment, especially for some areas with bare land in winter, the effect of planting green manure for one season is very good. Sow seeds in autumn, then cover them in winter to make them dormant, and then turn green in spring. It can not only make use of land resources for half a year, but also make full use of natural resources such as light and hot water. To improve the ecological environment, at the same time, green manure can also be used as forage raw material to ensure feed safety.

4. Reduce the cost

To plant crops, fertilization is naturally essential, and fertilizer is also very important to the growth of crops. And if you use common fertilizers such as chemical fertilizers, growers need to invest a lot of fertilizer costs. This leads to the decline of planting efficiency, and planting green manure can effectively reduce the input cost of chemical fertilizer and other fertilizers. In order to achieve the purpose of reducing planting costs and improving the planting efficiency of growers.

The above is a brief introduction to the role of green manure. That's all for today's introduction. This article is for reference only. I hope it can help you all.
