B51J:
Agricultural Systems: Links Between Hydrology and Biogeochemical Cycling I

Submit an Abstract to this Session



Session ID#: 31839

Session Description:
Agriculture plays an important role in hydrological and biogeochemical cycling on multiple temporal and spatial scales. The human dimensions of agriculture offer opportunities to alleviate changes to the biosphere through enhanced carbon sequestration, greenhouse gas emission management, and reduced water resources use. However, challenges of increased population and economic growth place continued demands on the agricultural sector to feed the world.

This session seeks submissions on the interaction of agriculture with water resources, hydrology, and biogeochemical cycling. Example issues could include the biogeochemical impact of fertilizer use, irrigation practices, land cover management, crop carbon-water relations, agricultural impacts on the surface energy balance, and interactions between agronomic practices and crop yield. Contributions may be from a variety of scales including plot, field and watershed. We welcome contributions that incorporate field or modeling components or their combination, research that crosses spatial and temporal scales, and seek a geographic diversity of presentations.
