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 ...
Effects of agronomic treatments on structure and function of ammonia-oxidizing communities
Author(s):Phillips, Carol J.; Paul, Eldor A.; Prosser, James I.; Gross, Katherine L.; Dollhopf, Sherry L.; Harris, Dave
Date Issued:2000-12
Format:born digital; articles
The aim of this study was to determine the effects of different agricultural treatments and plant communities on the diversity of ammonia oxidizer populations in soil. Denaturing gradient gel electrophoresis (DGGE), coupled ...
Comparison of nitrification rates in blueberry and forest soils
Author(s):Paul, Eldor A.; Ravenscroft, John; Serce, Sedat; Throop, Philip A.; Hanson, Eric J.
Date Issued:2002-01
Format:born digital; articles
Highbush blueberries (Vaccinium corymbosum L.) are long lived perennial plants that are grown on acidic soils. The goal of this study was to determine how blueberry cultivation might influence the nitrification capacity ...
Acid hydrolysis of easily dispersed and microaggregate-derived silt- and clay-sized fractions to isolate resistant soil organic matter
Author(s):Conant, R. T.; Paustian, K.; Paul, Eldor A.; Plante, A. F.; Six, J.
Date Issued:2006-08
Format:born digital; articles
The current paradigm in soil organic matter (SOM) dynamics is that the proportion of biologically resistant SOM will increase when total SOM decreases. Recently, several studies have focused on identifying functional pools ...
Interpretation of soil carbon and nitrogen dynamics in agricultural and afforested soils
Author(s):Gregorich, E. G.; Paustian, K.; Six, J.; Morris, S. J.; Paul, Eldor A.
Date Issued:2003-09
Format:born digital; articles
Interpretation of soil organic C (SOC) dynamics depends heavily on analytical methods and management systems studied. Comparison of data from long-term corn (Zea mays)-plot soils in Eastern North America showed mean residence ...
Does the acid hydrolysis–incubation method measure meaningful soil organic carbon pools?
Author(s):Conant, Richard T.; Morris, Sherri J.; Paul, Eldor A.; Plante, Alain F.
Date Issued:2006-05
Format:born digital; articles
The literature was reviewed and analyzed to determine the feasibility of using a combination of acid hydrolysis and CO2–C release during long-term incubation to determine soil organic carbon (SOC) pool sizes and mean ...
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 ...
Soil organic carbon pool changes following land-use conversions
Author(s):Paustian, Keith; Paul, Eldor A.; Morris, Sherri J.; Merck, Roel; Six, Johan; DeGryze, Steven
Date Issued:2004-07
Format:born digital; articles
Carbon (C) can be sequestered in the mineral soil after the conversion of intensively cropped agricultural fields to more extensive land uses such as afforested and natural succession ecosystems. Three land-use treatments ...
