Conservation practices focusing on improving the soil and water quality of working lands are implemented across the United States, supported partially through the United States Department of Agriculture Natural Resources Conservation Service cost-share or incentive payment programs. We assess whether participation in federal conservation support programs induces a change in the number of conservation practices adopted by farmers. We also identify the factors that affect the adoption intensity of different best management practices. We use survey data collected from Louisiana farmers and estimate models using the matching method and Poisson quasi-likelihood model. We find that participation in the cost-share or incentive program leads to an increase in the number of conservation practices on the farms. Similarly, the use of precision technology application and farm being integrated are likely to have a higher number of on-farm conservation practices. Results have implications for federal working lands conservation support programs in the United States.
美国各地都在实施侧重于改善工作土地土壤和水质的保护实践，部分得到了美国农业部自然资源保护服务成本分担或激励支付计划的支持。我们评估了参与联邦保护支持计划是否会导致农民采用的保护实践数量发生变化。我们还确定了影响不同最佳管理实践采用强度的因素。我们使用从路易斯安那州农民那里收集的调查数据，并使用匹配方法和泊松拟似然模型估计模型。我们发现，参与成本分担或激励计划会导致农场中保护实践的数量增加。同样，使用精确技术应用和农场一体化也可能会有更多的农场保护实践。这些结果对美国联邦工作土地保护支持计划具有重要意义。
