Second, Private agricultural extension services can promote farmers to adopt scientific fertilization technology through value perception and technology trusteeship. Third, heterogeneity analysis identifies technology-specific differences in the impact of private agricultural extension services on adoption decisions, showing stronger effects on the adoption of efficient fertilization techniques compared to novel fertilizer products.DiscussionThe research illuminates the micro-mechanisms through which private agricultural extension services operate and supports building a dual-driven “government-led, market-driven” agricultural technology diffusion system.
