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.†Reverse Circulation Water Well Drilling Rig Reverse circulation (or RC as it`s more commonly known) drilling is an essential tool in the mining industry. In addition to other oil rigs and drill rigs, reverse circulation drills assist in the productivity and accuracy in mining jobs.
It is the preferred method of mineral exploration, drilling and in-pit grade control because it is fast and cost-effective.
What is RC Drilling?
Reverse circulation drilling is the predominant technique based on a number of advantages.

RC drilling is a drilling method involving a large rotary drill and Air Compressor that yields high quality mineral and rock samples, free from contamination and material interference.
Much like air core drilling, RC drilling returns cutting to the surface through an inner tube inside the rod. This is achieved by blowing air down the rods at a rate up to 1500 Pascals. This creates a pressure differential that pushes cuttings and water up via air lift.
The drilling component is powered by a pneumatic reciprocating piston (also known as the hammer), which drives a steel drill bit.
The two most commonly used drilling bits in RC systems are the fixed cutter and roller cone, both of which are advantageous depending on the project and geographical location of the site.
RC drilling is primarily used on large machinery and drill rigs and often goes to depths of 500 metres.
High quality RC equipment also has the ability to dry out the rock with large air compressors before the drill hits, which provides dry rock chips and, in turn, better samples.
.A higher percentage of uncontaminated cuttings
.Drilling rate similar to open hole drilling, but can often be faster and penetrate greater depths
.One of the most accurate drilling methods
.Quick retrieval of sample rates
.Dry samples allow for easier analysis
