Based on a rural survey of 787 households in 6 major grain-producing provinces including Hebei，Shandong，Jiangsu，Anhui，Jiangxi and Hubei provinces，this article analyzed the influence of information acquisition channels and information acquisition ability on farmers’ outsourcing behavior in soil conservation by using Ordered Probit model.The results show that information acquisition exerts significant and positive impacts on farmers’ soil conservation outsourcing behavior.Specifically，the more information acquisition channels，the higher the extent of farmers’ outsourcing behavior in soil conservation.Although the direct effect of information acquisition ability on farmers’ outsourcing behavior in soil conservation is not significant，it can strengthen the positive effect of information acquisition channels on the behavior.In addition，although both formal and informal channels can significantly increase farmers’ outsourcing behaviour in soil conservation，only formal channels are significantly moderated by information acquisition ability.The effect of informal channels on farmers’ outsourcing behavior in soil conservation does not significantly change with the variation of information acquisition ability.Moreover，there are intergenerational differences for the impact of information acquisition on farmers’ outsourcing behavior in soil conservation.The effect of formal channels is more pronounced for farm households with younger decision makers.But for farm households with older decision makers，the effect of informal channels is more significant.And the formal channels have higher requirements for their information acquisition ability among the two types of farm households.Based on this，it is proposed that promoting farmers’ participation in soil conservation by means of social services should be one of the important measures to implement the strategy of “storing food in the land”.In this process，it is necessary to pay attention to the construction of different types of information transmission channels such as public organizations and social networks，and to strengthen the cultivation of farmers’ information acquisition ability，so as to provide guarantees for farmers’ participation in soil conservation.
