How much does soil affect agricultural products?

I think the impact of soil on agricultural products is huge.

The status and role of soils

As the basic material of agricultural production, soil can not only conserve and transform nutrients, but also conserve water and recycle, and can also provide support for biological growth and reproduction, so that environmental changes can be stabilized and buffered. Crops support our daily lives without soil. In recent years, agricultural production has gradually developed in the direction of modernization, and agriculture has developed sustainably.

It is the future development trend of agriculture, and in order to achieve this goal, it is necessary to build soil resources, improve soil utilization efficiency, and ensure soil recycling. Because of its regenerative nature, soil can be used as a renewable resource in agricultural development.

Ensure the sustainable development of agriculture. In addition, the soil can provide crops with water and nutrients and other energy in a continuous and comprehensive way, so that crops can grow healthily. It can be seen that soil is the material basis for the sustainable development of agriculture, so the production capacity of soil should be guaranteed.

Agriculture and the rural environment are the foundation and fundamental guarantee for human survival, economic development, and social stability. However, with the development of the economy and the growth of the population, the agricultural environment is facing a series of serious environmental pollution and ecological damage problems. The pollution of various elements of the environment will affect the normal quality of agricultural products, mainly through the analysis of the causes and characteristics of soil pollution and the relationship between soil pollution and the quality of agricultural products, the coordination of the relationship between man and nature is proposed, and the control methods and control technologies of soil environmental pollution are actively studied. Strengthen pollution-free means of production.

research on the development of technologies to reduce soil environmental pollution; Take the road of green agricultural development that saves resources, improves efficiency and reduces pollution, and ensures the safety of food production and agricultural products.

in the modernization of agriculture.

And intensive production today, industrial pollution and urban garbage transfer to the agricultural environment in large quantities, a large number of long-term irrational use of new agricultural chemicals in agricultural production, livestock and poultry excrement in veterinary drug residues and other increases, so that soil pollution is aggravated year by year, directly affecting the normal growth of plants and the quality of agricultural products, and experts pointed out that soil pollution causes harmful substances to accumulate in crops and through the food chain.

It enters the human body, causes various diseases, and ultimately endangers human health.

In general, the soil problem is a very serious problem to protect the environment.

Caring for nature is everyone's responsibility!

It is particularly large, and the fertility of the soil must be ensured in the process of planting, and the soil with good exclusion should be selected, and the sand and gravel soil or corroded soil should be selected as much as possible.

If the soil is not suitable for growing agricultural products, then the agricultural products will not grow much and will easily die.

The impact on agricultural products is very large, because the problem of soil will affect the yield of agricultural products, so it will also affect the economic benefits of farmers.

1. The development of agricultural production will cause changes in natural vegetation, surface environment, surface radiation characteristics and the carbon cycle in nature.

2. Unreasonable agricultural production methods will have an adverse impact on the geographical environment. For example, in semi-arid areas, overgrazing can lead to grassland degradation and even desertification; In irrigated agriculture in arid and semi-arid areas, unreasonable irrigation methods such as flood irrigation will lead to soil salinization.

3. The improvement of agricultural production technology has greatly increased the yield of crops, but also has some negative impacts on the ecological environment. For example, the heavy use of chemical fertilizers will make the soil compact; The widespread use of pesticides can lead to the contamination of agricultural products and soils.

Climate: Agricultural production has both advantages and disadvantages to the climate, and excessive reclamation and expansion of cultivated land destroys climatic conditions; But proper farming is good for the climate.

Hydrology: The use of water for agricultural production forces humans to build more water conservancy projects, which often causes certain damage to the hydrology and natural environment, in addition, the use of pesticides may also lead to water pollution, and the water environment is also damaged by lake reclamation.

Terrain: Terraces.

Soil: Irrational tillage leads to a decline in soil fertility and may even lead to desertification, but rational tillage is conducive to the maintenance of soil fertility, and the over-reclamation of the Loess Plateau leads to the destruction of vegetation, which is the main cause of soil erosion, but it also shapes the topographical characteristics of the Loess Plateau.

Vegetation: The expansion of arable land often presupposes the destruction of vegetation and even leads to the extinction of rare species.

Society: The people take food as the sky, the stable development of agriculture, and the quality of food is the foundation of social stability and people's living and working in peace and contentment.

Politics: Agriculture is the basic industry of the national economy and the foundation for a country to stand on its own feet in the world.

Agricultural production involves all fields of human production and life, and also affects the stable cycle of the entire ecosystem, and its impact on the geographical environment is divided into many aspects, and these aspects are interrelated. Learning should grasp this issue as a whole.

Any act that destroys soil fertility and pollutes soil causes soil hazards. For example, the single application of chemical fertilizers causes an imbalance in the proportion of soil nutrients; no fertilization, predatory farming; Acidification of the soil by excessive application of acidic fertilizers or pollution by atmospheric acid deposition; Unreasonable fertilization, destroying the physical structure of the soil, and making the soil compact; The three wastes and slag are discharged into the soil at will, directly polluting the soil; Irrational planting and irrigation lead to soil salinization.

Continuous cropping obstacles such as soil-borne diseases, soil degradation and desertification are all examples of soil destruction.

1. Heavy metals cannot be degraded by microorganisms and are long-term and potential pollutants in the environment;

2. Due to the adsorption of soil colloids and particulate matter, it exists in the soil for a long time, and the concentration is mostly distributed vertically;

3. It reacts with ligands (chloride ions, sulfuric acid ions, hydroxide ions, corrosives, etc.) in the soil to form complexes or chelates, resulting in greater solubility and migration activity of heavy metals in the soil;

4. Soil heavy metals can be bioenriched through the food chain to produce biomagnification;

5. The forms of heavy metals are different, their activity and toxicity are different, and the conditions such as soil pH, EH, particulate matter and organic matter content profoundly affect its migration and transformation in the soil;
