14pgs, While conservation practices promote soil health and reduce the negative environmental effects from agricultural production, their adoption rates are generally low. To facilitate farmer adoption, we carried out a survey to identify potential challenges faced by farmers regarding conservation tillage and cover crop adoption in the western margin of the US Corn Belt. We found farmers' top two concerns regarding conservation tillage were delayed planting, caused by slow soil warming in spring, and increased dependence on herbicide and fungicides. Narrow planting window and lack of time/labor were perceived by farmers as the two primary challenges for cover crop adoption. Some sense of place factors, including the commonly included dimensions of attachment, identity and dependence, played a role in farmers' perceived challenges. For example, respondents more economically dependent on farming perceived greater challenges. We found that farmers' challenge perceptions regarding reduced yield and lack of time/labor significantly decreased as years of usage increased, implying that time and experience could dilute some challenges faced by farmers. Our findings indicate that social network use, technical guidance and economic subsidies are likely to address the concerns of farmers and facilitate their adoption of conservation practices.
14 Pages, Science Direct, Public and private agricultural information sources are fundamental components that could overcome the barriers to adopting sustainable reduced tillage practices. This study aims to identify the information sources frequently used by farmers and their role in changing from conventional intensive tillage to reduced tillage practices. The study is focused on the Altai Krai region in southwestern Siberia, which faces severe soil degradation problems, pointing to an urgent need for sustainable reduced tillage practices in the area. It relied upon both quantitative and qualitative data that included a quantitative survey with 110 farm managers and qualitative, in-depth interviews with five farm managers. Descriptive statistics were used to explore farm characteristics and farmers’ actual usage of information sources. A logit model was used to estimate the role of agricultural information sources in the adoption of reduced tillage practices. Results show that the participation frequency of farm managers in trainings and workshops influences the adoption of sustainable reduced tillage practices in a statistically significant and positive way. However, the estimation results give that the frequency of expert consultations (from both private and public sources) does not influence the probability of adopting sustainable reduced tillage practices. This may be explained by the fact that farm managers received limited information about sustainable reduced tillage practices from these sources.
