Relationship between soil texture and soil fertility

Soil texture is a soil type divided according to the particle composition of soil. Soil texture is generally divided into three categories: sandy soil, loam soil and clay. Its types and characteristics mainly inherit the types and characteristics of parent materials, and are influenced by human factors such as farming, fertilization, irrigation and drainage, and land leveling. It is a very stable natural property of soil and has a great influence on soil fertility.

The more sticky the texture is, the better the ability of water and fertilizer conservation, the better the soil fertility, the more sandy the texture, the more serious the water leakage and fertilizer leakage, and the worse the fertility.

Soil fertility is the basic attribute and essential feature of soil, the ability of soil to provide and coordinate nutrients, moisture, air and heat for plant growth, and the comprehensive response of soil physical, chemical and biological properties. The four fertility factors are nutritional factors, physical factors, chemical factors and biological factors.

Extended data:

One of the most basic physical properties of soil has a great influence on various properties of soil, such as soil permeability, storage, tillage and nutrient content, which is an important basis for evaluating soil fertility and crop suitability. Different soil textures often have obviously different agricultural production characteristics. Understanding the types of soil texture is of guiding value to agricultural production.

There is no unified understanding of the concept of soil fertility in the world. Soil fertility is a comprehensive reflection of soil physical, chemical and biological properties, in which nutrients are the material basis of soil fertility, temperature and air are environmental factors, and water is both environmental and nutritional factors. Various fertility factors (water, fertilizer, gas and heat) exist at the same time, which are interrelated and restricted each other.
