We introduce a new model for examining the dynamics of uptake of technological innovations in agricultural systems, using the adoption of zero-till wheat in the rice-wheat system in Haryana state, India, as a case study. A new equation is derived which describes the dynamics of adoption over time and takes into account the effect of aggregation (e.g. on a spatial and/or cultural basis) in the adopting population on the rate of adoption. The model extends previous phenomenological models by removing the assumption of homogeneity in the non-adopting fraction of the population. We show how factors affecting the per capita rate of adoption can be captured using cognitive mapping and simulate the dynamics of the adoption process. |

The paper demonstrates a group incentive program to encourage farmer adoption of best management practices. It is demonstrated that the best management practices may not actually reduce farm profits but may increase farm profits and reduce environmental pollution. This may bring about a win-win situation for sponsor, the farmer participating in the program, and the society as a whole. The results show that the farmers subjective beliefs about response of corn yields and profits to nitrogen application differ from the simulated responses which in turn results in the willingness-to-Accept for adoption best management practices significantly higher than the expected program payments. The program could be implemented as an educational effort to... |

The adoption and possible abandonment of organic farming has yet received little attention in the literature. As time plays an important role in explaining farming decisions, a dynamic econometric framework, namely duration analysis, is used. The probability of entry to and exit of the organic drystock sector is modeled considering a wide range of economic and non‐economic factors. Organic support payments emerge as important driving factor of adoption over time. The empirical results also highlight the importance of environmental and risk attitudes, farming experience as well as influence of other organic farmers on the probability to adopt organic farming; whereas decisions to abandon organic farming appear to be mainly driven by economic and structural... |

Adoption of precision agriculture technology has arrived considerable attention, but abandonment has received little. This paper identified factors motivating adoption and abandonment of precision soils sampling in cotton. Younger producers who farmed more cotton area, owned more of their cropland, planted more non-cotton area, or used a computer were more likely to adopt precision soil sampling. Those with more cotton area or who owned livestock were more likely to abandon, while those who used precision soil sampling longer, or used variable-rate fertilizer application were less likely to abandon precision soil sampling. |

The full impact of an investment in a management information system (MIS), such as precision agriculture (PA), comes from improved managerial decision making throughout the whole farm and not just from improvements in a specific part of the farm. This study was conducted to determine whether the adoption of PA had a positive impact on whole-farm profitability. To overcome problems of simultaneity and self-selection in the adoption decision of PA, this study used a two stage econometric model using data from farms in Southwest Minnesota. The PA adoption decision was evaluated in the first stage, and the impact of adopting PA was evaluated in the second stage. The whole farm rate of return to assets (ROA) was used to measure the impact of PA. For all 212... |
