Experimental warming shows that decomposition temperature sensitivity increases with soil organic matter recalcitrance
Author(s):Haddix, Michelle L.; Conant, Richard T.; Steinweg, J. Megan; Six, Johan; Paul, Eldor A.; Plante, Alain F.
Date Issued:2008-09
Format:born digital; articles
Soil C decomposition is sensitive to changes in temperature, and even small increases in temperature may prompt large releases of C from soils. But much of what we know about soil C responses to global change is based on ...
Terminal restriction fragment length polymorphism data analysis for quantitative comparison of microbial communities
Author(s):Blackwood, Christopher B.; Marsh, Terry; Kim, Sang-Hoon; Paul, Eldor A.
Date Issued:2003-02
Format:born digital; articles
Terminal restriction fragment length polymorphism (T-RFLP) is a culture-independent method of obtaining a genetic fingerprint of the composition of a microbial community. Comparisons of the utility of different methods of ...
Agriculture's role in greenhouse gas mitigation
Author(s):Paul, Eldor A.; Sheehan, John; Antle, John M.; Paustian, Keith
Date Issued:2006-09
Format:born digital; articles
This report describes opportunities for U.S. agriculture to contribute to reducing net greenhouse gas emissions. The Pew Center on Global Climate Change was established by the Pew Charitable Trusts to bring a new cooperative ...
Measuring and understanding carbon storage in afforested soils by physical fractionation
Author(s):Paustian, K.; Paul, Eldor A.; Gregorich, E. G.; Morris, S. J.; De Gryze, S.; Lenders, S.; Callewaert, P.; Six, J.
Date Issued:2002-11
Format:born digital; articles
Forested ecosystems have been identified as potential C sinks. However, the accuracy of measurement and understanding of the underlying mechanisms for soil organic C (SOC) storage in forested ecosystems needs to be improved. ...
Managing soil carbon and nitrogen for productivity and environmental quality
Author(s):Robertson, G. Philip; Knezek, Bernard D.; Paul, Eldor A.; Parker, Elaine; Smeenk, Jeffrey; Kizilkaya, Kadir; Willson, Thomas C.; Harwood, Richard R.; Jose E., Sanchez
Date Issued:2004-05
Format:born digital; articles
In this study, we investigated the impact of cropping system management on C and N pools, crop yield, and N leaching in a long-term agronomic experiment in Southwest Michigan. Four management types, conventional (CO), ...
Visions of a more precise soil biology
Author(s):Coleman, D. C.; Paul, Eldor A.; Magid, J.; Kätterer, T.; Kirchmann, H.; Andrén, O.
Date Issued:2008-04
Format:born digital; articles
Soils have often been viewed as a black box. Soil biology is difficult to study with the precision we would wish, due to the presence of considerable soil heterogeneity, a huge diversity of organisms, and a plethora of ...
Corn root effects on the nitrogen-supplying capacity of a conditioned soil
Author(s):Harwood, Richard R.; Smeenk, Jeffrey; Willson, Thomas C.; Paul, Eldor A.; Sanchez, Jose E.
Date Issued:2002-05
Format:born digital; articles
The design of sustainable N management strategies requires a better understanding of the processes influencing the ability of soils to supply N to a growing crop. Although commonly ignored, the release of C by plant roots ...
Does physical protection of soil organic matter attenuate temperature sensitivity?
Author(s):Conant, Richard T.; Paul, Eldor A.; Six, Johan; Plante, Alain F.
Date Issued:2009-07
Format:born digital; articles
Global climate change may induce accelerated soil organic matter (SOM) decomposition through increased soil temperature, and thus impact the C balance in soils. We hypothesized that compartmentalization of substrates and ...
Use of carbon-13 and carbon-14 to measure the effects of carbon dioxide and nitrogen fertilization on carbon dynamics in ponderosa pine
Author(s):Paul, Eldor A.; Ball, J. T.; Johnson, D. W.; Cheng, W.; Haile-Mariam, Shawel
Date Issued:2000-11
Format:born digital; articles
Soil C sequestration in predicted, future elevated CO2 environments will be important to atmospheric CO2 levels, soil tilth, and fertility. An elevated CO2 study with ponderosa pines (Pinus ponderosa Laws) grown in chambers ...
Fractionation and long-term laboratory incubation to measure soil organic matter dynamics
Author(s):Paul, Eldor A.; Wright, S.; Collins, H. P.; Haile-Mariam, S.
Date Issued:2008-03
Format:born digital; articles
Soil organic matter (SOM) in agricultural soils comprises a significant part of the global terrestrial C pool. It has often been characterized by utilizing a combination of chemical dispersion of the soil followed by ...
