Abstract: To systematically understand the actual operation status, technical bottlenecks, and development demands of organic fertilizer enterprises in the fertilizer utilization of agricultural waste,from November 2021 to August 2024, a full-process survey was conducted on 81 organic fertilizer enterprises in 14 counties (cities, districts) of Hubei Province through a combination of field visits and questionnaire surveys. The results showed that organic fertilizer enterprises in Hubei Province were predominantly private (86.4%), 43.0% of enterprises had an annual production capacity of 30,000 tons or less, and the operational rate was 63.5%. The main raw material for organic fertilizer enterprises was chicken manure (64.2%), and auxiliary materials mainly included grain processing by-products such as rice bran (79.7%) and crop straw (78.5%). 88.9% of enterprises used fermentation agents in the production process. The mainstream fertilization processes were trough-type (56.2%) and windrow-type (25.0%), with a fermentation cycle of 30-60 days. The main products were ordinary organic fertilizer (90.1%), bio-organic fertilizer (69.1%), and organic-inorganic compound fertilizer (42.0%). Nearly 50% of enterprises lacked odor removal facilities, and even those that had them mostly adopted simple methods such as adding deodorizing agents. Regarding enterprise demands, 65.6% of enterprises hoped for more government support. The organic fertilizer industry as a whole was still in the early stage of development. Technically, there was an urgent need to break through shortcomings such as raw material pretreatment, functional agent application, and environmental control. Policy-wise, organic fertilizer enterprises should be integrated into the agricultural infrastructure system, with coordinated planning and collaborative advancement, to achieve efficient, green, and sustainable resource utilization of agricultural waste.
