Última Assessing Investment in Precision Farming for Reducing Pesticide Use in French Viticulture AgEcon Lescot, Jean-Marie; Rousset, Sylvain; Souville, Genevieve. The paper develops a mathematical programming model for assessing the impact of Environmental Policy instruments on French winegrowing farm’s adoption of pesticides-saving technologies. We model choices with regards to investment in precision farming and plant protection practices, in a multi-periodic framework with sequential decision, integrating uncertainty on fungal disease pressure and imperfect information on equipment performance. We focus on recursive models maximizing a Utility function. These models are applied on a representative sample of 534 winegrowers from the French Farm Accountancy Data Network (FADN). As expected, both ecotaxes and green subsidies make precision farming equipment more profitable, but the investment rate remains however...

Ano: 2011 URL: http://purl.umn.edu/114387 Can Education Be a Barrier to Technology Adoption? AgEcon Uematsu, Hiroki; Mishra, Ashok K.. The objective of this study is to test the widely‐held belief that the effect of education has a positive impact on technology adoption. Using 2006 Agricultural Resource Management Survey "ARMS" data, we estimate a simultaneous equations model to integrate farmers’ labor allocation decision with adoption of GM crops and precision farming. We confirm that the marginal effect of education on technology adoption is significantly larger for large farms for both GM crops and precision farming and it is unexpectedly negative for GM crops at all levels of farm size. These results suggest that formal education can be a barrier to technology adoption, especially for small scale farmers who have higher tendency to work off‐farm.

Ano: 2010 URL: http://purl.umn.edu/60971 Factors Influencing Cotton Farmers’ Perceptions about the Importance of Information Sources in Precision Farming Decisions AgEcon Velandia, Margarita M.; Lambert, Dayton M.; Mendieta, Maria P.; Roberts, Roland K.; Larson, James A.; English, Burton C.; Rejesus, Roderick M.; Mishra, Ashok K.. Information generated by precision farming technologies is of particular importance to producers. Precision farming technologies implies the ability to improve the management of production factors using site-specific information. This study examines factors influencing cotton farmers’ perceptions about the importance of crop consultants, farm input dealerships, Extension, other farmers, trade shows, the Internet and printed news/media for making precision farming decisions using a rank ordered logit model (ROLM). Results suggest that age, land tenure, income, percentage of income from farming, and location may affect farmers’ perceptions about the importance of different information sources when making decisions about precision farming technologies....

Ano: 2011 URL: http://purl.umn.edu/103752 Motivation for Technology Adoption and Its Impact on Abandonment: A Case Study of U.S. Cotton Farmers AgEcon Uematsu, Hiroki; Mishra, Ashok K.; Roberts, Roland K.; Lambert, Dayton M.; English, Burton C.. We estimate a bivariate probit model with sample selection to identify factors affecting adoption and abandonment of precision farming technologies for cotton farmers, using the 2009 Southern Cotton Precision Farming Survey conducted in 12 Southern states in the United States. Farmers for whom being at the forefront of agricultural technology is not an important reason for adoption are more likely to abandon precision farming technologies. This study identified various factors associated with adoption and retention of precision farming technologies. Findings from this study offer significant information to policy‐makers for a better formulation of agri‐environmental programs that encourage farmers to adopt environmentally benign farming practices...
