What are the core functions of organic matter on soil and crops?

Organic matter can be said to be an indispensable substance in the soil. It not only improves the soil properties, but also plays a very important role in crop cultivation. It can be said to be the most effective helper for the soil. The higher the content of organic matter in a certain range, the more fertile the soil. So, what are the core functions of organic matter on soil and crops? Let's listen to what Xiaonong.com says.

First, the main source of soil nutrients

The organic matter contains various nutrients needed for crop growth, and can provide nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and various trace elements for crop growth directly or simply. In particular, nitrogen in the soil, most of which is present in the soil in an organic state. The carbon dioxide produced by the decomposition of soil organic matter can supply green plants for photosynthesis.

Second, promote the growth and development of crops

Humic acid in organic matter can enhance plant respiration, increase cell membrane permeability, and enhance the absorption of nutrients. At the same time, vitamins and some hormones in organic matter can promote plant growth and development.

Third, improve soil structure and physical properties

The humus in the organic matter can reduce the viscosity of the viscous soil, improve the agglomeration of the sand, and improve the soil structure and physical properties.

Fourth, improve soil fertility

The organic colloid in the soil organic matter has a strong adsorption capacity and can adsorb a large amount of cations and water, so it can improve the ability of the soil to maintain fertilizer and water storage.

Fifth, increase soil temperature

The color of organic matter is generally brown to dark brown, which is darker and darker, so it has a strong heat absorption capacity and can help to raise the ground temperature.

It is precisely because of the above-mentioned organic effects of organic matter, so the soil is not strong in water and fertilizer, and the nutrition of crops is also very rich. In the actual crop planting, farmers should increase the application of organic fertilizers according to the actual situation, improve the soil organic matter content, in order to increase the soil's effective fertility, so that the crops grow robustly and achieve a good harvest.

Imported Premium Fire Retardant

Flame retardants, functional auxiliaries endowed with inflammable polymer flammability, mainly designed for flame retardancy of polymer materials; There are many types of flame retardants, which can be divided into additive flame retardants and reactive flame retardants according to their usage.

The additive type flame retardant is added to the polymer by mechanical mixing method to make the polymer flame retardant. At present, the additive type flame retardant mainly includes organic flame retardant and inorganic flame retardant, halogenated flame retardant (organic chloride and organic bromide) and non-halogenated flame retardant. Organics are some flame retardants represented by bromine, phosphorus and nitrogen systems, nitrogen systems, red phosphorus and compounds, while inorganic flame retardants are mainly antimony trioxide, magnesium hydroxide, aluminum hydroxide and silicon systems.
