After more than 18 months, the implementation of the livestock waste management component has brought about practical results in Ben Tre

Effective biogas works

Ms. Phan Thi Thu Suong, Director of Project Management Unit of LCAC in Ben Tre province, said that the project will be implemented from 2013 to 2018 with 4 components: livestock waste management; Credit for biogas value chains; Transfer of low carbon agricultural production technology and Project Management.

After more than 18 months, the implementation of the component of animal waste management has brought about practical effects. The localities have built 2,380 / 3,600 small scale works, volume of 50 m3 or less. With this progress, until the end of quarter 2/2016, Ben Tre will complete the plan. Leverage to accelerate the project is to support 3 million / works, Bank for Agriculture and Rural Development loans 80% / total project value, interest is equal to 90% of current interest rates. At the same time, the LCASP Management Board of the province actively coordinated with the District People's Committee, branches, unions, People's Committees of communes and townships; Especially, the agricultural sector promotes propaganda and mobilizes people to participate. Biogas works are economically and socially meaningful, making use of gas produced in daily activities such as cooking, lighting, running generators.

In particular, the work contributes to reduce environmental pollution of livestock and protect the health of families and communities. By-products of the project include wastewater and residues used to irrigate plants as fertilizer for crops that are free of fecal contamination. Ben Tre Agricultural and Fishery Extension Center has noted that many households utilizing waste water from biogas plants have overcome the shortage of water for orchard farms without having to buy fertilizer.

Solid waste pumped onto the shore is permeable to the soil creating a new layer of porous soil, which helps to root the plant. With this soil layer, gardeners do not have to take muddy soil and cover their roots. Experimental results also show that using liquid byproducts from leaf biogas plants increases average yield by about 10% compared to direct application to soil. If fertilization in combination with inorganic fertilizers increases the solubility and absorption of chemical fertilizers of the soil; At the same time limiting nutrient depletion, increasing the efficiency of using NPK from 10 to 30%. In addition, this approach also promotes microbial activity, keeps manure for soil, makes soil softer, and avoids soil loss due to excessive application of chemical fertilizers.

Mr. Nguyen Chanh Binh, deputy director of Ben Tre Agricultural and Fishery Extension Center, said that using bioslurry from the biogas plant to irrigate crops, replacing chemical fertilizers, contributes to saving production costs, friendly To the environment. Ms Thu Suong affirmed that the livestock waste management component has made a significant impact, and the local authorities expect the project to support the second phase in the near future and implement the component of low-carbon agricultural production. Help the community benefit. As for the credit component for biogas value chains, up to now, 148 households have borrowed more than 2.3 billion VND to build the project.
