Quản lý rơm rạ thông qua sản xuất phân bón hữu cơ tại huyện Tân Hưng, tỉnh Long An

Abstract

Facing the urgent need to address the negative environmental impacts of rice straw burning while simultaneously seeking sustainable agricultural development solutions, this study was conducted to evaluate the management of rice straw through organic fertilizer production by local farmers in Tân Hưng District, Long An Province. Data were collected from interviews with 67 households utilizing rice straw for organic fertilizer application and 23 local leaders from October to December 2023. The results revealed the advantages of the rice straw-based organic fertilizer model compared to open-field burning in terms of ecological, economic, and socio-cultural aspects. The production cost for one ton of rice straw- based organic fertilizer was VND 4.191 thousand, generating revenue of VND 4.320 thousand, and yielding a net profit of VND 129 thousand. The rice cultivation model combined with organic fertilizer application achieved a profit of VND 78.75 million/ha/year, which was VND 8.35 million/ha/year higher than the rice cultivation model using only inorganic fertilizer. The SWOT analysis results identified several strategies for developing organic fertilizers in the locality, such as encouraging businesses and households to participate in the production of organic fertilizers from rice straw, and developing appropriate support policies to promote production and expand the organic fertilizer market through environmental awareness campaigns.
