The relationship between soil and health Did you know

A: Soils are central to the exchange and circulation of materials in ecosystems. Soil and environmental factors such as air, water, and plants (food) are interconnected and inseparable.

Therefore, soil is one of the main factors of the human environment, and the quality of soil sanitation has a great impact on people's health, residents' living and production conditions. People's clothing, food, shelter and transportation are directly or indirectly related to soil. The composition and physicochemical properties of the soil can affect the microclimate and can change the atmospheric temperature and relative humidity.

If you live in low-lying and high groundwater level areas for a long time, often due to dampness and cold, buildings, clothes, food, utensils, etc. can easily rot, and residents are prone to rheumatism, pharyngitis, neuralgia and other diseases; If there is a lack of moisture in the soil, it can dry out the atmosphere, the temperature fluctuates drastically, and the dust flies, which can easily cause diseases such as ocular conjunctivitis and upper respiratory tract inflammation. Trace elements in the soil can seep into groundwater, can also be absorbed by the roots of plants, and ingested into the human body through food, drinking water and air; It has become a substance necessary for the growth and development of the human body. Some trace elements (such as fluorine, iodine, cadmium, selenium, etc.) can affect the physiological function of the human body and even cause chronic poisoning.

Soil is a natural place for the reception and purification of various wastes, which is easily polluted by feces, garbage, sewage, etc. without harmless treatment, and may become a breeding and breeding place for pathogens, rodents, parasites, etc. For example, soil is a vector for diseases such as hookworms, roundworms, anthrax, tetanus, gas gangrene and Clostridium botulinum. Contaminated soil can pollute surface water and groundwater through rainwater erosion and infiltration, and can cause the spread and epidemic of infectious diseases such as typhoid, dysentery, viral hepatitis, polio and schistosomiasis.

The polluted soil contains a large amount of organic matter, and in the process of decay and decomposition, it emits foul-smelling and unpleasant gases such as ammonia and hydrogen sulfide, polluting the air, thus causing the external environment to be filthy and unclean, and causing people's disgust. If the soil is already heavily contaminated, it is very difficult to remediate, and the impact on the health of the population is often long-lasting and wide-ranging. Therefore, it is of great hygienic significance to strengthen the treatment and harmless measures of contamination to prevent soil pollution for the prevention of diseases and the protection of residents' health.

Certain mineral elements and microorganisms in the soil are beneficial to human health, while certain heavy metals and microorganisms are pathogenic or lethal to humans and other animals.

Summary. Hello dear! 10 Characteristics of Soil Health!

1.The soil tillage characteristics are good. This is a general characteristic of the soil's ability to grow healthy crops.

The soil is not easily compacted and is easily infiltrated by air and water, while still having sufficient water-holding capacity. 2.The depth of the tillage layer is sufficient.

Is the topsoil deep enough for the roots to stretch, or is there a hard bottom layer due to nature or the grower? 3.Nutrients are plentiful but not excessive.

Are the levels of nutrients adequate and accessible and absorbable? Is the nutrient cycle good, or is there an excess of nutrients that are prone to leaching and runoff, endangering the survival of microorganisms? 4.

Populations of plant pathogens and pests are controllable. Is there an increase in beneficial organisms in the soil, and can harmful organisms be suppressed at the same time? 5.

The soil is well drained. Healthy soils drain quickly due to good structure and pore space while still retaining enough water for plant growth. 6.

Plenty of beneficial organisms. Beneficial microorganisms are important for the decomposition of organic matter, nutrient cycling, soil structure, pest suppression, and others. 7.

Low pressure on weeds. Proper soil management, such as cash crop and cover crop production, can help reduce the pressure on weeds.

Which is the diseased soil and which is the healthy soil.

Hello, which is the healthy soil and which is the sick soil.

Hello dear! 10 Characteristics of Soil Health! 1.

The soil has good tillage characteristics. This is a general characteristic of the soil's ability to grow healthy crops. The soil is not easily compacted and is absolutely and easily permeable by air and water, while still having sufficient water-holding capacity.

2.The depth of the tillage layer is sufficient. Is the topsoil deep enough for the roots to stretch, or is there a hard bottom layer due to nature or the grower?

3.Nutrients are plentiful but not excessive. Are the levels of nutrients adequate and accessible and absorbable?

Is the nutrient cycle good, or is there an excess of nutrients that are prone to leaching and runoff, endangering the survival of microorganisms? 4.Populations of plant pathogens and pests are controllable.

Is there an increase in beneficial organisms in the soil, and can harmful organisms be suppressed at the same time? 5.The soil is well drained.

Healthy soils drain quickly due to good structure and pore space while still retaining enough water for plant growth. 6.Plenty of beneficial organisms.

Beneficial microorganisms are very important for the decomposition of organic slippery residue substances, nutrient cycling, soil structure, pest inhibition, and others. 7.Low pressure on weeds.

Proper soil management, such as cash crop and cover crop production, can help reduce the pressure on weeds.

8.Free from harmful chemicals, irritants and toxins. Healthy soils do not contain harmful chemicals and toxins, socks or have the ability to neutralize toxins, so they do not adversely affect plant and microbial growth.

9.Resistance to degradation. The soil is highly resistant to wind and water erosion and soil compaction.

10.Resilient when adverse conditions arise. Healthy soils recover quickly from adverse conditions such as drought or late harvesting in wet conditions.
