Conservation practices preserve soil quality and may also increase the value of agricultural land. The economic benefits of conservation practices include increased agricultural yields, decreased risk of production losses from weather events, decreased number of farming operations, simplification of farm management, and decreased production costs. We analyze the links between soil conservation practices and the value of agricultural lands. The soil conservation practices considered in this study include no-tillage, crop rotation, contour farming, and the use of agricultural terraces. We use municipal data on annual crops in the state of Paraná from the 2006 Brazilian Census of Agriculture. Results show that the average value of lands under conventional tillage is between 10 and 22% lower than lands under no-tillage, ceteris paribus. The economic benefits of adopting no-tillage can be maximized when performed in conjunction with other conservation practices, including crop rotation, contour farming, and agricultural terracing. Finally, we discuss the critical effect of soil conservation and conservation agriculture on land prices and how these factors may affect farmers’ decision-making.

土壤保持如何影响农业土地价格

保护措施可以保持土壤质量，也可以增加农业用地的价值。保护措施的经济效益包括增加农业产量、降低天气事件造成的生产损失风险、减少农业作业数量、简化农场管理和降低生产成本。我们分析了土壤保持实践与农业用地价值之间的联系。本研究中考虑的土壤保持做法包括免耕、轮作、等高耕作和农业梯田的使用。我们使用 2006 年巴西农业普查中巴拉那州一年生作物的市政数据。结果表明，在其他条件不变的情况下，常规耕作土地的平均价值比免耕土地低 10% 至 22%。与其他保护措施（包括轮作、等高耕作和农业梯田）结合使用时，可以最大限度地提高采用免耕的经济效益。最后，我们讨论了水土保持和保护性农业对土地价格的关键影响以及这些因素如何影响农民的决策。
