The document is a presentation from the Vietnam Academy of Agriculture Science, specifically the Northern Mountainous Agriculture and Forestry Science Institute (NOMAFSI), focusing on the recycling of rice plant residues to improve land quality and promote sustainable agricultural practices. It discusses the issue of rice straw residues, which amount to approximately 50 million tons in Vietnam annually. Historically, these residues were either burned or discarded, leading to air pollution and loss of a valuable carbon source. The document details NOMAFSI's development of techniques for "quick composting" rice straw using a microbial product (EM) that accelerates decomposition.
