What we should do to protect the soil, what we can do to protect the soil in our hometown

Soil degradation simply refers to: soil erosion; soil desertification; soil salinization; Soil pollution; deterioration of soil properties; Non-agricultural occupation of cultivated land...

Therefore, the main ways to protect the soil are: afforestation, reducing soil desertification and soil erosion, reducing the use of pesticides and inorganic fertilizers, and direct discharge of industrial waste... Increase the area used with organic fertilizer, thereby increasing the fertility of the soil...

Also, to minimize the area of non-agricultural land use... Advocate returning farmland to forests... Prohibition of unrestricted animal husbandry...

1. Soil provides essential nutrients and water for plants, and is also the habitat for soil animals, so human beings get the basic conditions for survival;

2. The development of various industries of the national economy is inseparable from land. Sufficient, high-quality and reasonably distributed land is one of the necessary conditions for the smooth development of the national economy of mankind;

3. Land is the core relationship in human production relations. In human economic life, land ownership determines the production relations based on land ownership, that is, the mutual relations and distribution relations between people in the process of reproduction.

4. When other conditions are constant, the quantity, quality and distribution of land determine the population load of land and the quality of human life on average.

Strengthen the construction of soil environmental protection systems. Improve soil environmental quality standards, and formulate measures for the supervision and management of soil environmental protection and technical specifications for agricultural product producing areas. Research and establish a system for assessing and filing the soil environmental quality of land used for construction projects and a system for the investigation, assessment and restoration of polluted soil, and clarify the responsible entities and requirements for governance and restoration.

Due to the urbanization of human beings, the construction of cities occupies a large amount of land, in addition, human activities such as white garbage, waste batteries, solid waste, etc. have caused great damage to the soil, and more seriously, the current land desertification is serious, these reasons have directly led to the shrinkage of agricultural land area, and the global environment is more harsh, so the protection of soil has been a key topic for environmental activists.

% of food comes from the soil.

Food comes from the soil. It is estimated that 95% of food is grown directly and indirectly from soil. Therefore, the availability of food depends on the soil. Only healthy soils can produce healthy, high-quality food. Healthy living soils are important for food security and nutrition.

2. Soils contain a quarter of the world's biodiversity.

Soil is one of nature's most complex ecosystems: it contains an infinite number of different organisms, whose interactions promote global cycles that sustain all life. Soils contain a quarter of the planet's biodiversity, which is essential for food security and nutrition.

3. There are more than 1,000 species of invertebrates in one square forest soil.

More than 1,000 species of invertebrates can be found in every square meter of forest soil, and the soil provides the necessary conditions for these organisms to survive.

4. One gram of healthy soil contains millions of organisms.

One gram of healthy soil contains millions of organisms, including vertebrates, earthworms, nematodes, 20-30 species of mites, 50-100 species of insects, hundreds of species of fungi and thousands of species of bacteria and actinomycetes.

5. At present, 33% of the world's soils are degraded

Globally33 percent of soils are estimated to be moderately to highly degraded due to soil erosion, salinization, compaction, acidification, chemical pollution and nutrient depletion.

6. 28% of the crops produced globally are wasted.

It is estimated that 28 percent of the crops produced on the world's farms are wasted. The process consumes 250 cubic kilometres of water, and the carbon footprint of produced but not eaten food is estimated at 3.3 billion tonnes of CO2e.

7. It takes hundreds to thousands of years on average for one centimeter of soil to form.

On average, one centimeter of soil can take hundreds to thousands of years to form. The main factors for soil formation are: climate, topography, parent material, time and biological factors (plant, animal, microbial and human).

Different combinations and the intensity of soil-forming factors result in the production of different soil types.

8. Sustainable soil management can increase crop yields by an average of 58%.

Sustainable soil management practices, such as agroecology, organic agriculture, conservation agriculture, agroforestry and no-till, can increase crop yields by an average of 58 percent.

9. Soils contribute to climate change mitigation and adaptation.

Through carbon sequestration and greenhouse gas reduction, soils play a key role in the carbon cycle, contributing to climate change mitigation and adaptation.

10. Soil provides important ecological services for the earth's organisms.

Soils provide key ecosystem services, such as the production of food, fuel, energy and medicinal products; clean air and water; gas exchange and carbon sequestration; Wait a minute. Ultimately, these sustain all life.

Plant more trees and afforestation, and use forests and grasses to reduce urban water loss.

Planting more trees, forests should be forested, grass should be grassed, rational use of soil resources to protect the environment, reduce the discharge of urban wastewater and solid waste.

To answer the question of soil protection, it is necessary to make unified planning for agriculture, forestry, animal husbandry, and industry, rationally utilize and manage soil resources, balance soil production input and output, adapt soil productivity to bearing capacity, and improve soil fertility, soil productivity, and environmental landscape. The purpose of soil conservation can only be achieved by taking biological measures as fundamental measures and combining them with appropriate engineering measures.

The causes of soil pollution are complex, and the main pollution sources include: industrial "three wastes"; urban residents' domestic waste; agrochemicals; livestock and poultry breeding waste, etc.

The harmfulness of soil pollution: After the soil is polluted, its original characteristics will be destroyed, the quality of crops will also decline, and the surface contaminated soil is easy to enter the atmosphere and water bodies under the action of wind and water, resulting in ecological and environmental problems such as air pollution, surface water pollution and groundwater pollution.

4) Application of chemical amendments and biological improvement measures The application of inhibitors in soil mildly polluted by heavy metals can convert heavy metals into insoluble compounds and reduce the absorption of crops. Commonly used inhibitors include lime, alkaline phosphate, carbonate and sulfide. For example, the application of lime or alkaline furnace ash in acidic or slightly acidic soil contaminated with cadmium can convert active cadmium into insoluble substances such as carbonate or hydroxide, and the improvement effect is significant.

Because most of the heavy metals are sulfur-loving elements, the application of green manure and straw in paddy fields, and the application of an appropriate amount of sodium sulfide and stone sulfur mixture on dry land are conducive to the formation of insoluble sulfides by heavy metals. For arsenic contaminated soil, Fe2(SO4)3 and MgCl2 can be applied to generate FeaSO4, Mg(NH4)2, ASO4 and other insoluble substances to reduce the harm of arsenic. In addition, it can be planted.

Take a look and give a thumbs up if you can.

Planting trees and picking up mulch.

Throw less garbage, grow more trees, and emit less exhaust gases.

Plant more trees and emit less emissions.

Do you know what soil pollution is? What are the causes of soil pollution? Soil contamination has become a major challenge to build a healthy environment.

So, today let's find out what soil pollution is and how does it happen? I believe you must be wondering what exactly is soil pollution?

Soil pollution refers to the abnormal toxic substances contained in the soil, such as garbage debris, toxic chemicals, etc. In other words, soil contamination occurs when the level of this toxic and harmful substance in the soil increases enough to cause serious damage to living organisms such as plants, animals, and humans. What causes soil pollution?

There are many factors that contribute to soil pollution. From the waste generated by large factories, to the overuse of pesticides on agricultural land, to the trash we throw away at home and school, the waste we create is one of the most polluted on the planet. Garbage collected from home or school is taken to landfills, where it is buried in the soil and decomposes over time.

Decomposition releases the greenhouse gas methane, which can contribute to global warming.

Not only that, but different kinds of soil contamination can adversely affect the health of animals and humans, as harmful chemicals entering the soil and water can cause cancer, deformities, and many other problems. Knowing about soil pollution, what can we do to prevent it? As people say, if you want to change the world, you have to start with yourself, starting with the little things like garbage in life, which will have a huge impact on protecting the environment.

The best way to control waste is to reduce production, such as not using paper towels or napkins. Drink from a glass, not from a plastic bottle, and make sure to dispose of hazardous waste such as batteries and computer equipment properly. Everyone acts together, and soon there will be a clean environment.

Do you know? The planet loses 24 billion tonnes of topsoil every year due to land pollution.

Causes of soil pollution Waste gas, waste water, and solid waste discharged from the production and operation activities of enterprises. Agricultural production activities, such as sewage irrigation, chemical fertilizers, pesticides and agricultural films, livestock and poultry breeding, pollutant emissions, etc.

There is excessive use of pesticides, or illegal emissions from enterprises to form soil pollution. When burning, this is only part of the reason.

It's because we litter the soil, and there is a lot of plastic pollution in it, which will affect our soil.

methods for improving soil moisture content;

Mulching and water saving can improve the water content: including plastic film mulching, straw mulching is also called straw mulching, and sound grass mulching for fruit trees.

Chemical water conservation can improve soil water content: water-retaining agents, drought inhibitors, and anti-transpiration inhibitors are applied.

The application of organic fertilizer can increase soil moisture content and improve soil structure.

Ways to improve water use efficiency:

Water use efficiency, the yield per unit volume of water.

Therefore, increasing yields, reducing irrigation, reducing evaporation and transpiration between classes, reducing surface runoff, and reducing underground leakage are all ways to increase water use efficiency.

Afforestation is the most protective of the soil.

1.It is necessary to control and eliminate the sources of soil pollution, strengthen the management of the "three wastes" in industry, and rationally apply chemical fertilizers and pesticides.

2.For the types of soil pollutants, plant plants with strong absorption capacity to reduce the content of toxic substances.

3.Purify the soil through biodegradation (e.g. earthworms can degrade pesticides, heavy metals, etc.).

4.The application of inhibitors changes the migration and transformation direction of pollutants in the soil, reduces the uptake of crops (e.g. lime application), increases the pH of the soil, and promotes the formation of hydroxide precipitation of cadmium, mercury, copper, zinc, etc.

5.Soil pollution can also be controlled by increasing organic fertilizer, changing the farming system, changing the soil, and deep ploughing.

1. Poor water conservancy infrastructure seriously restricts the scale of land development and utilizationDue to the lack of reservoirs in the mountainous areas of Xinjiang and the poor ability to regulate and control water resources, it is not possible to achieve reasonable irrigation at the right time and in the right amount. In addition, the leakage loss of the canal system in Xinjiang is serious, the field irrigation technology and management are backward, the facilities for water distribution and water measurement in the field are seriously insufficient, and the gross irrigation quota is high. The land is poorly leveled, and the water resources entering the fields are not fully and efficiently utilized, resulting in a waste of irrigation water.

2 The contradiction between agricultural land and construction land is becoming increasingly prominent, Xinjiang is an arid region, and the main form of land use is oasis use mode. Due to the severe constraints of water volume and water resource utilization technology, it is impossible to arbitrarily expand the area of artificial oases. With the implementation of the strategy for the large-scale development of the western region, the construction of the "four big" bases and new industrialization, and the advancement of the construction of a moderately prosperous society, urbanization, and new countryside, the contradiction between cultivated land and construction land in Xinjiang has become increasingly prominent, and higher requirements have also been put forward for the scale, quality, and level of land use, and the area of cultivated land occupied by construction land is expanding year by year.

Lin Yusuo, director of the Soil Pollution Prevention and Control Research Center of the Nanjing Institute of Environmental Sciences of the Ministry of Environmental Protection, pointed out in the lecture hall that in the face of the severe situation of soil environmental protection, the state is or will take a series of measures to strengthen soil environmental protection and pollution control, and resolutely declare war on soil pollution. The first is to formulate and implement an action plan for the prevention and control of soil pollution, and make overall arrangements for soil environmental protection and pollution control at the national level. The second is to accelerate the legislative process of soil environmental protection and provide legal support for soil environmental protection.

The third is to carry out a detailed investigation of the status of soil pollution to further find out the status of soil environmental quality. Fourth, implement soil remediation projects and promote soil pollution control and restoration in a planned and step-by-step manner. Fifth, strengthen soil environmental supervision and prevent new soil pollution through iron fists and iron rules.

On April 17, 2014, the Ministry of Environmental Protection (MEP) and the Ministry of Land and Resources (MLR) issued a communiqué on the national soil pollution survey, announcing to the public the overall state of the national soil environment, the exceedance of various pollutants, the soil environmental quality of different land use types such as cultivated land and forest land, and the soil pollution status of typical plots such as industrial and mining waste land and their surroundings.
