Bio-organic fertilizer is a type of fertilizer compounded by specific functional microorganisms and organic materials mainly derived from animal and plant residues (e.g., livestock manure, crop straw, etc.), which have undergone harmless treatment and decomposition. Its core advantages in agricultural application are reflected in multiple dimensions such as soil improvement, crop quality enhancement, and ecological protection, as detailed below:

1. Improving soil physical and chemical properties and enhancing soil fertility

    - It supplements soil organic matter, improves soil aggregate structure, addresses soil compaction caused by long-term application of chemical fertilizers, and enhances soil air permeability as well as water and fertilizer retention capacity.

    -Functional microorganisms (such as nitrogen-fixing bacteria, phosphorus-solubilizing bacteria, potassium-solubilizing bacteria) can activate fixed nutrients like nitrogen, phosphorus, and potassium in the soil, converting ineffective nutrients into forms absorbable by crops and extending the supply cycle of soil fertility.

    - It regulates soil pH, and is particularly suitable for the remediation and improvement of saline-alkali soil and acidified soil, creating a favorable soil environment for crop root growth.

2. Promoting crop growth and improving agricultural product quality

    -Bioactive substances (e.g., auxins, cytokinins) secreted by functional microorganisms can stimulate the development of crop roots, enhance the root system’s ability to absorb water and nutrients, promote robust crop growth, and improve lodging resistance as well as disease and pest resistance.

    - It reduces the application amount of chemical fertilizers and pesticides, lowers the residues of harmful substances such as nitrates and heavy metals in agricultural products, improves the taste, flavor and nutritional value of agricultural products, and meets the production requirements of green and organic agricultural products.

    - It accelerates crop maturation, extends the harvest period, and increases the commercial value of agricultural products.

3. Enhancing the stability of farmland ecosystem and reducing environmental risks

    - Functional microorganisms can form dominant microbial communities in the soil, inhibit the reproduction of pathogenic bacteria and harmful microorganisms, reduce the occurrence of soil-borne diseases, and lower the environmental pollution risk caused by pesticide application.

    - It avoids problems such as nitrogen loss and water eutrophication caused by excessive application of chemical fertilizers, and protects the water environment and ecosystem around farmland.

    - It promotes the resource utilization of agricultural wastes (e.g., straw, livestock manure), reduces environmental pollution caused by waste accumulation, and realizes the sustainable cycle of agricultural production.

4. Reducing agricultural production costs and improving planting benefits

    - Bio-organic fertilizer can replace part of chemical fertilizers, reducing the procurement cost of chemical fertilizers; meanwhile, it cuts down the pesticide input for pest and disease control, saving field management costs.

    - Crops applied with bio-organic fertilizer see steady yield increase and better product quality, which gives them a stronger price advantage in the market and significantly improves the economic benefits of growers.
