Scientists' understanding of soil fertility has caused many people to have no understanding of soil fertility. What is soil fertility in the end? What are the characteristics of soil fertility? The soil nutrient tester is a scientific instrument developed and designed by Zhejiang Top Instrument for the determination of soil nutrients and soil fertility in agricultural growth. Today we talk about the different understanding of soil fertility.

Phylogenetics (1974) on soil fertility compiled by the Yunnan Forestry College states: “The soil has the ability to provide the nutrients, moisture, and rooting conditions required for forest growth, and is called soil fertility.” and states that “soil fertility is not elusive, it It is represented by various physical, chemical, and biological characteristics of the soil.” This concept of soil fertility is based on the book Soil (1965), edited by the Ministry of Agriculture of the People's Republic of China: The ability to meet the conditions for eating (nutrition), drinking (moisture), and living (building a foothold) that are needed for crop growth in a timely manner is called soil fertility.” Prepared.

The book “Chinese Soil” (1978), edited by the Nanjing Institute of Soil Science, Chinese Academy of Sciences, states that the concept of soil fertility is: “The ability of the soil to supply and coordinate plant nutrition and environmental conditions.” This concept of soil fertility produces fertility. The reason boils down to two conditions. At the same time, it is also considered that “soil fertility is a comprehensive reflection of the physical, chemical, and biological properties of the soil.” Also based on its relationship to plant growth, the soil fertility factor is “divided into two aspects: nutritional and environmental factors. Nutrients are nutritional factors, temperature and air are environmental factors, and water is both environmental and nutritional factors."

In Shenyang Agricultural College, "Agricultural Soil Science", in I.Lieberoth's "Polology and Soil Fertility" and in "Chinese Soil" book, both have the regulation properties of soil as a sign of soil fertility. In addition, there is a strong emphasis on understanding the fertility of the soil economically, such as F. Seheffer, P. Sehaehtsehabel (1976), who believes that soil fertility means: “The ability of the soil to serve as a plant site and to produce plant harvests.”
