Soil quality is an important determinant of agricultural productivity, farm resilience and environmental quality. Despite its importance, the incorporation of sustainable soil management in economic models is lacking. This study approaches farmers as decision makers on soil management. Sustainable soil management may be an investment that goes at the expense of short-term returns but increases future soil quality. Hence, the key problem is economic: establishing long-term sustainable soil management at a minimized loss of income. In this study, we define the Economic Value of Land $(EVL)$ as the cumulative returns of a piece of land over a period in time. Maximum long-term $EVL$ is obtained if a soil’s potential is maximally utilized in a sustainable way. From this follows that the Economic Value of Sustainable soil Management $(EVSM)$ is defined as the difference between a sustainable and unsustainable $EVL$. To acquire a fundamental understanding of $EVSM$, agronomic and technical factors must be integrated with economics. Production management, the complete set of physical and non-physical inputs is the primary determinant of future soil quality and hence $EVL.$ Maximizing $EVL$ first requires a fundamental understanding of soil quality management: What are the properties of soil quality and how are these influenced by crop production? Subsequently, production management has to be organized in such a way $EVL$ is maximized. This study provides an overview of soil quality management and crop production management linked to economics. The framework provides a qualitative blueprint for bio-economic modelling and a basis for policies to enhance sustainable soil management.

土壤质量是农业生产力、农场恢复力和环境质量的重要决定因素。尽管它很重要，但缺乏将可持续土壤管理纳入经济模型。本研究将农民视为土壤管理的决策者。可持续土壤管理可能是以短期回报为代价但会提高未来土壤质量的投资。因此，关键问题是经济问题：以最小的收入损失建立长期可持续的土壤管理。在本研究中，我们定义了土地的经济价值$(乙伏升)$作为一块土地在一段时间内的累积收益。最大长期$乙伏升$如果以可持续的方式最大限度地利用土壤的潜力，就可以获得。由此可见，可持续土壤管理的经济价值$(乙伏秒米)$ 被定义为可持续和不可持续之间的区别 $乙伏升$. 获得基本的了解$乙伏秒米$，农艺和技术因素必须与经济相结合。生产管理，完整的物理和非物理投入是未来土壤质量的主要决定因素，因此$乙伏升.$ 最大化 $乙伏升$首先需要对土壤质量管理有基本的了解：土壤质量的特性是什么，这些特性如何受作物生产的影响？随后，必须以这种方式组织生产管理$乙伏升$被最大化。本研究概述了与经济学相关的土壤质量管理和作物生产管理。该框架为生物经济建模提供了定性蓝图，并为加强可持续土壤管理的政策奠定了基础。
