Influencing Factors of Grain Farmers' Application Behavior to Adopt Organic Fertilizer from the Perspective of Heterogeneity-Based on The Empirical Study of 512 Farmers in Sichuan Province

Based on the survey data of 512 households in Sichuan Province, this paper uses the binary logistic model to analyze the influencing factors of organic fertilizer application behavior of grain farmers in the perspective of heterogeneity. The study shows that the organic fertilizer application behavior of grain farmers is a complex decision-making behavior under the interaction of various heterogeneous factors. In terms of human capital, grain farmers who are young, highly educated and have a large family labor force are more likely to apply organic fertilizers; in terms of economic capital, grain farmers with high household income and high proportion of agricultural income are more likely to apply organic fertilizer; in terms of social capital, grain farmers who joined farmers' specialized cooperatives and received training on organic fertilizer and had some family members who have served as village cadres prefer to apply organic fertilizer. In terms of natural capital, the large scale of cultivated land and the low degree of fragmentation of cultivated land are conducive to promoting the application of organic fertilizers to grain farmers.
