    Achieving more sustainable agricultural production: investigating the impact of agricultural machinery services on fertilizer reduction based on survey data from wheat farmers by Chenyang Liu, Wei Guo, Ling Xin

    Published 2025-07-01
    “…To rigorously identify the effects of AMS on FAI, we employ a combination of linear regression, Least Absolute Shrinkage and Selection Operator (LASSO), two-stage least squares (2SLS), and mediation effect analysis to account for potential confounders and mechanisms.ResultsThe empirical analysis reveals three main findings: (1) AMS significantly reduce FAI, and the extent of reduction increases with higher levels of participation in AMS. (2) The FAI-reducing effect of AMS varies substantially across farmers with different socio-economic and farm characteristics. (3) Technological progress and changes in traditional fertilization practices are two key mediating mechanisms through which AMS lower FAI.DiscussionThese findings suggest that promoting AMS can effectively reduce FAI while supporting sustainable agricultural development. …”
