Advancing Agroecosystem Management in a Changing Climate from Bottom Up: the Hydrogeologist’s Perspective
Advancing Agroecosystem Management in a Changing Climate from Bottom Up: the Hydrogeologist’s Perspective
Session ID#: 122701
Session Description:
Soil health is a critical driver of economic prosperity and world peace and thus is essential to the UN’s 2030 development goals. However, we have an incomplete understanding of what drives the underlying biophysical processes. These include linked microbial respiration and nutrient mineralization processes that influence soil carbon sequestration, nutrient leaching to waterways, and greenhouse gas emissions. Although soil moisture is widely known to affect microbial function and nutrient/gas transport, linkages between soil health and hydrogeologic setting remain uncertain. The dynamic nature of near-surface ground- and surface-water interactions likely affects the relative importance of “top-down” versus “bottom-up” (i.e., precipitation versus groundwater) controls on soil moisture and geochemical conditions across space and time. We invite contributors to illuminate how a hydrogeologic framework can advance our understanding of why cropland soil health varies within and among farm fields in different hydroclimatic regions worldwide.
