Abstract:
Current soil survey products provide critical information on the diversity and variation of static soil properties across the country, and how these influence crop production potential and management options. These static, or inherent, properties only change over geologic periods of time. There are, however, other soil properties that define soil health status, which change over shorter time scales. These are often referred to as dynamic soil properties, and can be measured through soil health indicators. These not only contribute additional influence on crop production potential and risk, but also are in turn changed on time scales of months, years, and decades, by crop production and soil management methods chosen by the producer. Furthermore soil biological influences on soil physical and chemical functioning are being increasingly highlighted as drivers of agroecosystem functioning. Such temporal interactions between inherent and dynamic soil properties and management represent the future of expanded soil survey products. We must address the need for information on rates of change to dynamic soil properties as influenced by specific human soil management approaches through monitoring, to provide updated status information. Concurrently there is a need for identifying location- and condition-specific approaches for using management to enhance soil dynamic properties, or soil health. Such information will benefit producers and the public in their efforts to assess, manage, enhance, monitor, and value the soil health status of the landscapes they work with.  Collaborative opportunities for use of current and future soil survey and soil health monitoring and enhancement products to inform development of locally adapted soil health management systems will be discussed.
