Root-water table interactions in corn-soybean systems

In this study we investigate how groundwater table depth may influence plant growth above- and below-ground through affecting the vertical distribution of roots. The purpose of this project is to identify traits associated with acquisition capability for above- and below-ground resources and responses to different levels of water table, as well as to assess the effects of such growth conditions on: 1) above total biomass, 2) total root growth, morphology and distribution through the soil profile and 3) the relationship of these root traits with physiological yield components.
