Abstract

This study was conducted in Bac Son and Duc Hoa communes (Soc Son district, Hanoi) to evaluate straw biomass and analyze common management practices. The research team directly measured 90 field samples of straw and paddy, while conducting structured interviews with 200 farming households and four forcus group discussions. The results indicated that on average, each square meter of rice field produced 1,07 kg/m² fresh straw and 0.78 kg/m² fresh of paddy. The dry matter composition of the straw included: organic carbon (OC) accounting for 52.36%, total nitrogen (Nts) 1.16%, potassium (K₂Ots) 2.05%, and phosphorus (P₂O₅) 0.4%. The total estimated amount of dry straw in 2024 is approximately 14675,78 tons, with Bắc Sơn contributing a higher proportion. Farmers primarily handled straw by feeding it to livestock, mulching crops, soil incorporation, bedding material, and open-field burning. Straw management behaviors were shaped by post-harvest field conditions, harvest timing, weather, and on-farm utilization needs. The study proposes several solutions, including technical support for appropriate treatment, developing pilot models, creating market outlets, and applying administrative measures.
