Measuring and monitoring soil organic carbon stocks in agricultural lands for climate mitigation
Author(s):Paul, Eldor A.; Ogle, Stephen M.; Conant, Richard; Paustian, Keith
Date Issued:2011-04
Format:born digital; articles
Policies that encourage greenhouse-gas emitters to mitigate emissions through terrestrial carbon (C) offsets – C sequestration in soils or biomass – will promote practices that reduce erosion and build soil fertility, while ...
Controls on soil carbon sequestration and dynamics: lessons from land-use change
Author(s):Conant, Richard; Brewer, Elizabeth; Mellor, Nathan; Morris, Sherri J.; Paul, Eldor A.
Date Issued:2010-03
Format:born digital; articles
Soil carbon (C) dynamics and sequestration are controlled by interactions of chemical, physical and biological factors. These factors include biomass quantity and quality, physical environment and the biota. Management can ...
Microbial responses to multi-factor climate change: effects on soil enzymes
Author(s):Steinweg, J. Megan; Dukes, Jeffery S.; Paul, Eldor A.; Wallenstein, Matthew D.
Date Issued:2013-06
Format:born digital; ariticles
The activities of extracellular enzymes, the proximate agents of decomposition in soils, are known to depend strongly on temperature, but less is known about how they respond to changes in precipitation patterns, and the ...
Changes in ecosystem carbon following afforestation of native sand prairie
Author(s):Paul, Eldor A.; Stromberger, M. E.; Morris, S. J.; Drijber, R.; Hellerich, J.; Mellor, N. J.
Date Issued:2013-09
Format:born digital; articles
Determining the dynamics of carbon (C) as a function of vegetation and residue inputs is important for predicting changes in ecosystem functions and the global C cycle. Litter and soil samples were analyzed from plantations ...
Role of soil characteristics on temperature sensitivity of soil organic matter, The
Author(s):Paul, Eldor A.; Morris, Sherri J.; Drijber, Rhae A.; Margrini-Bair, Kim; Steinweg, J. Megan; Six, Johan; Conant, Richard T.; Plante, Alain F.; Haddix, Michelle L.
Date Issued:2011-01
Format:born digital; articles
The uncertainty associated with how projected climate change will affect global C cycling could have a large impact on predictions of soil C stocks. The purpose of our study was to determine how various soil decomposition ...
Diffuse-reflectance Fourier-transform mid-infrared spectroscopy as a method of characterizing changes in soil organic matter
Author(s):Haddix, Michelle; Margrini-Bair, Kimberly; Conant, Richard; Calderón, Francisco; Paul, Eldor A.
Date Issued:2013-09
Format:born digital; articles
Diffuse-reflectance Fourier-transform mid-infrared spectroscopy (MidIR) can identify the presence of important organic functional groups in soil organic matter (SOM); however, spectral interpretation needs to be validated ...
Microbial efficiency-matrix stabilization (MEMS) framework integrates plant litter decomposition with soil organic matter stabilization, The: do labile plant inputs form stable soil organic matter?
Author(s):Wallenstein, Matthew D.; Denef, Karolien; Boot, Claudia M.; Cotrufo, M. Francesca; Paul, Eldor A.
Date Issued:2013-04
Format:born digital; articles
The decomposition and transformation of above- and below-ground plant detritus (litter) is the main process by which soil organic matter (SOM) is formed. Yet, research on litter decay and SOM formation has been largely ...
Carbon allocation, belowground transfers, and lipid turnover in a plant–microbial association
Author(s):Paul, Eldor A.; Schultz, David J.; Calderón, Francisco J.
Date Issued:2012-09
Format:born digital; articles
Radioactive tracers were used to study the C allocation to coarse and fine roots, aboveground plant tissues, mycorrhizal lipids, belowground respiration, and soil in a mycorrhizal association. Sorghum bicolor (L.) Moench ...
Chemical differences in soil organic matter fractions determined by diffuse-reflectance mid-infrared spectroscopy
Author(s):Collins, Harold P.; Reeves, James B.; Calderón, Francisco J.; Paul, Eldor A.
Date Issued:2011-03
Format:born digital; articles
We performed mid-infrared (MidIR) spectral interpretation of fractionated fresh and incubated soils to determine changes in soil organic matter (SOM) chemistry during incubation. Soils from four sites and three depths were ...
