Soils are the largest terrestrial pool of carbon, therefore it is critical to understand
what controls soil carbon efflux to the atmosphere in light of current climate uncertainty.
The primary efflux of carbon from soil is soil respiration which is typically categorized
into autotrophic and heterotrophic respiration. These two components...

Data on soil temperature at two locations and five depths, tensiometer readings, and soil moisture release curves for the soils of Findley Lake are presented in this report.
Under adverse soil moisture conditions a critical water stress
or water potential develops in the plant and productivity is reduced,
or in extreme cases, terminated. Research to determine the soil
moisture status for maximum production of specific crops has been
conducted for decades. The results have done much to increase...
Understanding how the interactions and feedbacks between plant function, climate, and soils ultimately affects the terrestrial water balance and subsurface flow processes is major challenge in scientific hydrology. This dissertation summarizes the findings of a manipulative climate warming experiment, an observational field study that utilized stable-isotope tracers, and associated modeling...
Based on the determination of the zero-flux plane, a water balance procedure
for large-scale experimental databases was automated to estimate the soil water
balance based on soil water content distribution with depth through time. The
automated procedure was verified using data from the BOREAS project obtained in
three Intensive Field...
