What are the effects of organic fertilizers on agricultural planting?
Organic fertilizer, a slow-release fertilizer rich in a large amount of biological matter, animal and plant residues, excrement and biological waste, plays a vital role in the agricultural field. Its wide range of application scenarios and significant effects are mainly reflected in the following aspects:
- Improve soil structure
Increase soil organic matter: Organic fertilizer is rich in a large amount of organic matter. These organic matter can be converted into humus after being decomposed by microorganisms in the soil, thereby increasing the organic matter content of the soil.
Improve soil physical properties: Humus can enhance the soil’s structure, making it loose and porous, and improve the soil’s air permeability and water retention. This helps the growth and development of the root system and enhances the stress resistance of crops.
- Improve soil fertility
Provide comprehensive nutrients: Organic fertilizer contains various nutrients required for crop growth, such as nitrogen, phosphorus, potassium and trace elements. These nutrients are slowly released in the soil, providing continuous nutrition for crops and meeting their needs at various growth stages.
Enhance soil fertilizer retention capacity: Humus in organic fertilizer has a strong adsorption capacity, which can absorb and retain nutrients in the soil, reduce nutrient loss, and improve soil fertilizer retention capacity.
- Promote microbial activity
Provide carbon source and energy: Organic fertilizer provides rich carbon source and energy for microorganisms in the soil, which helps the growth and reproduction of microorganisms.
Improve soil microecological environment: The activity of microorganisms can improve the microecological environment of the soil, promote the transformation and circulation of soil nutrients, and improve soil fertility.
- Improve crop quality
Increase crop nutrition: The nutrients in organic fertilizer are comprehensive and balanced, which can provide sufficient nutrition for crops, make crops grow strong, and improve the quality of crops.
Improve the taste and flavor of crops: The use of organic fertilizer can also improve the taste and flavor of crops, making crops more delicious.
- Enhance crop resistance
Improve crop resistance to drought and cold: Organic fertilizer can improve the structure and aeration of the soil, improve the water retention capacity of the soil, and thus enhance the drought and cold resistance of crops.
Enhance crop resistance to diseases and pests: The nutrients and microbial activities in organic fertilizers can enhance the immunity of crops and improve the resistance of crops to diseases and pests.
- Reduce environmental pollution
Reduce the use of chemical fertilizers: The use of organic fertilizers can reduce the use of chemical fertilizers, thereby reducing the pollution of chemical fertilizers to the environment.
Reduce soil and water pollution: The nutrients in organic fertilizers are slowly released in the soil, reducing the loss and leaching of nutrients, and reducing the risk of pollution to soil and water.
- Promote sustainable agricultural development
Improve the sustainable utilization capacity of soil: The use of organic fertilizers can improve the structure and fertility of the soil and improve the sustainable utilization capacity of the soil.
As a green and environmentally friendly fertilizer, the widespread use of organic fertilizers will help promote the development of green agriculture and achieve the sustainable development goals of agriculture.
