What are the benefits and harms of soil animals to the soil

Soil fauna have a variety of benefits for soil, the main ones are:

1.Activate the soil and enhance soil fertility: The activities of soil fauna can mix different layers of soil, increase soil porosity, reduce soil volume and quality, improve soil structure, and promote soil formation and nutrient cycling.

2.Promote nutrient circulation: By feeding and decomposing litter and microorganisms, soil animals accelerate the nutrient cycle and promote the growth and development of trees, melons, fruits and grains in the natural ecosystem.

3.Remediation of degraded soils: Soil fauna can degrade pesticide residues, purify sewage, absorb or enrich heavy metals, help protect ecosystems, and remediate degraded soils.

However, soil fauna can also pose some potential hazards. For example, in some cases, they may damage a plant's root system or cause other forms of biological hazards. In addition, under specific environmental conditions, soil animals can become vectors for the transmission of diseases.

As an important consumer in the material cycle of the ecosystem, soil animals play an important role in the ecosystem, actively assimilating various useful substances to build themselves, and on the other hand, returning their excretory products to the environment and continuously transforming the environment.

1. Crop production function: soil can fix plant roots, has natural fertility, can promote crop growth, and carry out agricultural production. This is one of the earliest recognized functions of soil, including agriculture, forestry production, and food crops.

and cash crop production.

2. Animal and plant habitat function: for the purpose of protecting rare animals and plants, to ensure that the soil can provide habitat for plants and animals. Soils, whether as or possibly as habitats for some particular or rare species, have high conservation value.

The function of soils as habitats for plants and animals (or potential habitats for plant and animal communities) is essential for the conservation and enhancement of biodiversity.

It has an important role.

3. Regulatory function: the function of soil as a component of nature and the interaction with other environmental factors. Moisture cycling is included.

Function, i.e., the quantity and quality of water infiltration and retention of soil in the water cycle. Nutrient cycling function, that is, the ability to supply plant nutrients in nutrient cycling; Carbon storage function, i.e. in the carbon cycle.

, the storage function of soil for organic carbon and inorganic carbon, especially for organic carbon; Buffer filtration function, that is, the buffer filtration function of soil for heavy metals; Decomposition and transformation function, that is, the decomposition and transformation function of soil to organic pollutants.
