Defining good soil has been a topic of interest for soil scientists, with various frameworks such as tilth, soil fertility, soil quality, soil security, and soil health emerging. While research on soil health parameters has provided insights into their response to land management, it has generated limited knowledge on how to manage lands to maximize environmental and agronomic benefits. This lack of insight is attributed to the underemphasis of important knowledge areas and the need for innovation in soil health measurements. This lack of practical knowledge poses risks for policy and practice in sustainable food systems.
Defining what makes a good soil has long been of interest to soil scientists. Over the years, several conceptual frameworks have emerged to serve this purpose: tilth, soil fertility, soil quality, soil security, and soil health. There has been a growing body of research assessing how various management practices impact indicators of good soils. We argue that the growing body of research on soil health parameters has advanced our knowledge of how these indicators respond to land management, but produced little insight into how lands should be managed to increase environmental and agronomic benefits. We believe this lack of insight is due to under -emphasis of several knowledge areas: Is an increase in a soil health property good or bad? How much do desirable outcomes change when a soil property changes, and is the relationship between the two linear? Can land management change soil indicators by a sufficient magnitude to cause the desired change in outcome? And, what new indicators are needed to enable innovation in agricultural systems? Innovation in soil health mea-surements is important because the lack of practical insight into how to manage land risks dampening enthu-siasm and innovation about the role soils can play in transitioning to sustainable food systems; it means that policy & practice risks moving forward without a strong evidence base.
