Ứng dụng vi sinh trong canh tác nông nghiệp bền vững tại huyện Quốc Oai
Environmental pollution is a burning problem not only for developing countries but also for many developed countries. In Vietnam, the pollution situation is getting worse and worse. Currently, the amount of domestic waste being mixed and dumped directly into the environment is increasing in quantity, creating great pressure on the units of garbage handlers. Nationwide, domestic waste in urban areas generates 35,000 tons daily, with a collection and treatment rate of more than 85%. This figure in rural areas is 28,000 tons daily and only collects about 55% of the total waste (national environment report 2016-2021).
According to estimated data, the country generates more than 60,000 tons daily. However, only about 15% of the collected waste is recycled or reused. The rest is buried in landfills, discharged into water sources, or burned. Realizing that garbage is a great resource if we classify and treat it properly, in 2022, under the sponsorship of Irish Aid, the Center for Development and Integration has coordinated with the Dan Phuong District Farmers’ Association, the Association of Women in Quoc Oai district have developed over 200 models of organic waste classification and application of microorganisms to treat waste as organic fertilizer in five communes.
After one year of implementation, the models have shown good results. The total amount of organic waste classified and treated is estimated at up to 30 tons; After composting, about 6 tons of organic fertilizer is produced. These practical activities have greatly reduced environmental pollution, waste collection, and transportation costs. At the same time, it has helped farmers reduce their dependence on chemical fertilizers for small family vegetable gardens, where they actively source quality green vegetables for life.
Technical training on waste classification and treatment at Ngoc Liep commune, Quoc Oai district, Hanoi
The Center for Development and Integration cooperates with the Women’s Union of Quoc Oai district to promote the movement of sorting and treating organic waste as fertilizer for crops. Together they organize training sessions, share experiences on classification, and treat organic waste as fertilizer for people in Ngoc Liep, Liep Tuyet, Dong Quang, Nghia Huong, Dong Xuan communes of Quoc Oai district, Hanoi from April 12-14, 2023. After three days in the workshop, 230 participants, including households sorting organic waste at home, better understand the role and meaning of waste separation at source and know how to apply microorganisms in organic waste treatment to make fertilizers. At the same time, it can take advantage of other agricultural by-products to compost to bring value and efficiency.
The trainees also shared how to make organic fertilizer from locally available natural seafood, such as composted fish and snails, as fertilizer; this is a fertilizer with high nutritional value and is suitable for various plants. The good application of the composting process will produce nutritious products at very low prices, increasing farmers’ income. In addition, the trainees were also instructed to share their experience in producing fertilizers from seeds, such as composting soybeans, peanuts, etc. Also, they shared how to make pesticides using locally available herbs such as garlic. , chili, ginger, galangal, lemongrass, etc., to minimize the use of fertilizers and toxic plant protection chemicals in production.
