The adoption of conservation practices is a dynamic process. Factors that vary over time can affect farmers’ decision to adopt and adoption timing. We used a duration model to evaluate the farmer's adoption time for continuous no‐till (CNT), cover crops (CCs), and the variable‐rate application of inputs (VRA). We found that producers who had previously adopted soil conservation practices were more likely to adopt additional complementary practices. Farmers using crop rotation adopted CNT and CCs approximately 48% and 62% faster than farmers without a crop rotation, respectively. The CC adoption time was also reduced by 70% for farmers who had adopted CNT. Complementarities between conservation practices may enhance the benefits from adoption and allow farmers to adopt bundles of conservation practices more quickly over time. This can be taken advantage of in conservation programs by promoting or requiring practices first that enhance adoption of other practices. We also found important heterogeneity in the adoption speed associated with farm management characteristics, producers’ attitudes, weather patterns, and crop prices.

保护实践的补充和农场采用的时间

采用保护措施是一个动态的过程。随时间变化的因素会影响农民的收养决定和收养时间。我们使用持续时间模型来评估农民的连续免耕（CNT），覆盖农作物（CCs）和可变利率投入物（VRA）的采用时间。我们发现，以前采用土壤保护措施的生产者更有可能采用其他补充措施。使用轮作的农民比不进行轮作的农民采用CNT和CC的速度分别快48％和62％。对于采用碳纳米管的农民，采用CC的时间也减少了70％。保护措施之间的互补性可能会增加采用带来的收益，并使农民随着时间的流逝更快地采用一系列保护措施。可以在保护计划中加以利用，方法是首先促进或要求加强其他实践的采用。我们还发现与农场管理特征，生产者的态度，天气模式和农作物价格相关的采用速度存在重要异质性。
