Organic matter plays a vital role in soil, which can significantly improve the water and fertilizer retention capacity of soil. This is mainly due to several reasons:
First of all, organic matter is a natural "sponge" that is able to absorb and store large amounts of water. When the moisture content in the soil is high, organic matter is able to absorb water and store it for later use. During periods of drought, this stored water can be released slowly, providing the plant with sustained water**.
Secondly, organic matter can improve the permeability of the soil. It acts like a bridge that connects the various particles in the soil, allowing water and nutrients to penetrate better into the soil. In this way, the root system of the plant is able to absorb water and nutrients more easily, which in turn improves the growth efficiency of the plant.
In addition, organic matter improves the structure of the soil. It is able to interact with minerals and microorganisms in the soil to form a structure called an "agglomerate". These aggregates act like cells that encapsulate the various particles in the soil, making them less easily washed away by water or blown away by the wind. In this way, the water and nutrients in the soil are better protected and provide continuous nutrients to the plants**.
Finally, organic matter is also able to provide the nutrients that plants need. It itself is rich in carbon, nitrogen, phosphorus, and other elements, which are necessary for plant growth. When organic matter breaks down, these elements are released into the soil to provide nutrients to plants.
In summary, organic matter improves the water and fertilizer retention capacity of soil in a variety of ways. It is like a clever housekeeper, carefully maintaining the health of the soil and providing a strong guarantee for the growth of plants.
