The role of microbial organic fertilizer for organic farming


Organic farming is an agricultural industry that is based on scientific knowledge combined with soil fertility and land reclamation measures to ensure product quality and long-term land use. In addition, the important role of organic matter in soil fertility has been widely acknowledged. Organic matter contributes to improving physical and chemical properties as well as soil biology and provides many important nutrients for plants. The supply of trace elements, nutrients from organic fertilizers makes sense in increasing the quality of agricultural products, making fruits sweeter and less pests. Fertilizing organic fertilizer is a necessary source of food for soil microorganisms: metabolism, nutrient circulation in soil, nitrogen fixation, nitrification, decomposition of residues of real protection drugs objects as well as inhibit the activity of microorganisms that are detrimental to plants.

Organic farming is an agricultural production management system that avoids the use of synthetic fertilizers and pesticides, minimizing air, soil and water pollution, optimizing human and animal health.
Due to the need to ensure food security, the abuse of fertilizers and plant protection chemicals to improve crop productivity is becoming an issue that needs to be improved. Beside ensuring the goal of food security, attention should be paid to the development of Organic farming to contribute to the provision of safe products for domestic and export needs. Organic farming helps farmers save cost of pesticides and chemical fertilizers and can diversify crops and cultivate in a sustainable way. Moreover, if certified agricultural products can be exported at higher prices.
According to the Food and Agriculture Organization of the United Nations (FAO), organic agriculture is capable of ensuring enough food supplies to feed the world’s population today in parallel with minimizing harmful effects on the environment. school

The basic principles of International Federation of Organic Agriculture Movements (IFOAM) presented in 1992 are as follows:
– Producing food with high quality nutrition, sufficient quantity;
– Encourage and promote the biological cycle in farming systems, including microorganisms, flora and fauna populations in soil, plants and animals;
– Maintain and increase the fertility of cultivated land in the long term;
– Use as much as possible renewable sources in organized agricultural systems in the local;
– Minimize the types of pollution resulting from agricultural production;
– Maintain genetic diversity in organic farming systems and the area around it, including plant protection and the habitat of wild nature.

Organic microorganisms supplemented with beneficial microorganisms are products produced from various organic materials, to provide nutrients for plants, improve soil, contain one or more strains of microorganisms. Living is selected with the density of prescribed standards, contributing to improving productivity and quality of agricultural products. Microorganism organic fertilizer does not adversely affect people, animals, ecological environment and quality of agricultural products. In addition to improving crop yields as well as agricultural quality (which is most evident through the nitrate residue index in the product), the efficiency of microbial organic fertilizer is also shown by improving properties. Soil includes physical, chemical and biological soil properties.

Organic matter is also a source of food for living organisms in the soil. Most soil microorganisms belong to saprophytic groups. The main food source of this group is excess and plant waste. Supply of organic substances helps maintain food sources, facilitates biomass development, diversifies species and inhibits the growth of harmful microorganisms.

Maintaining the beneficial microbial balance in the soil is mainly to protect and balance beneficial microorganisms, as well as beneficial natural enemies in the field. Therefore, regular addition of organic matter to soil as well as beneficial microbial sources to create favorable conditions for root development to limit pathogens. The application of organic fertilizer supplemented with soil microorganisms such as Trichoderma will reduce pathogens of root rot on tomatoes and chili, supplementing sources of nitrogen fixing microorganisms and dissolving phosphorus, increasing fertilizer sources. Fixed nitrogen and poorly soluble phosphorus compounds become useful and easily digestible forms for plants.

Organic farming focuses on the use of micro-organic fertilizer to limit plant protection chemicals and chemical fertilizers, contributing to improving the quality of agricultural products and soil fertility, ensuring the need for sustainable development. while ensuring the ability to maintain crop productivity.
