Technical Abstract: Soil degradation threatens global food production and security, clean water and air, and animal and human health. Different forms and rates of degradation occur and can be categorized into three types of degradation - chemical, physical, and biological – each of which does not exists individually but is the product of multiple interactions and feedback loops. Chemical deterioration primarily involves loss of nutrients and/or soil organic matter (SOM), salinization, acidification, pollution, and eutrophication. Physical deterioration includes loss of soil, nutrients, and SOM from wind and water erosion, compaction, sealing, crusting, water logging, loss of rooting depth. Biological deterioration is likely the least understood but critical to overall soil function and crop productivity and involves the loss of biodiversity, keystone taxa or consortia, and an overall reduction in efficient biological processes. Soil microbes play a direct role in driving multiple soil chemical and physical processes important for overall ecosystem function, but also have direct and indirect effects on plant productivity and quality. As a result, we suggest that soil conservation and regeneration should focus not only erosion and soil loss but also on the status of the soil biological community, its function, and overall soil health.
