Elevated moisture stimulates carbon loss from mineral soils by releasing protected organic matter
Moisture response functions for soil microbial carbon (C) mineralization remain a critical
uncertainty for predicting ecosystem-climate feedbacks. Theory and models posit that C …

Quantifying the contribution of tile drainage to basin-scale water yield using analytical and numerical models
Abstract The Des Moines Lobe (DML) of north-central Iowa has been artificially drained by
subsurface drains and surface ditches to provide some of the most productive agricultural …

Subsurface nutrient export from a cropped field to an agricultural stream: Implications for targeting edge-of-field practices
It is understood that the major transport pathways for the soluble nutrients nitrate (NO 3-N)
and orthophosphorus (OP) from cropped fields to streams in the US Cornbelt are tile …

Poorly drained depressions can be hotspots of nutrient leaching from agricultural soils
SJ Hall, CG Tenesaca, NC Lawrence, DIS Green… - 2023 - Wiley Online Library
Much of the US Corn Belt has been drained with subsurface tile to improve crop production,
yet poorly drained depressions often still flood intermittently, suppressing crop growth …

Inundation patterns of farmed pothole depressions with varying subsurface drainage
A Martin, AL Kaleita, ML Soupir - Transactions of the ASABE, 2019 - elibrary.asabe.org
Highlights Farmed pothole depressions in the Des Moines Lobe were observed to fill due to
runoff and shallow subsurface flow. Six of the eight observed potholes flooded for five or …
