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 ...
Extraction and charaterization of humus with reference to clay-associated humus
Author(s):Anderson, D. W.; Paul, E. A.; St. Arnaud, R. J.
Date Issued:1974-08
Format:born digital; articles
An extraction-fractionation method was developed with which it is possible to isolate 60–67% of the humus of Chernozemic and Luvisolic soils. Two humic acid fractions were obtained: (1) a conventional alkali-pyrophosphate ...
Decomposition of 14C-labelled plant material under field conditions
Author(s):Paul, E. A.; Shields, J. A.
Date Issued:1973-08
Format:born digital; articles
Mature, uniformly labelled (14C, 15N), chopped, wheat straw incorporated in the plow layer of a Brown Chernozemic soil and a Gray Wooded soil was allowed to decompose in the field. Labelled grass material (14C) was added ...
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 ...
Investigations of the dynamics of soil humus utilizing carbon dating techniques
Author(s):Rennie, D. A.; Campbell, C. A.; Paul, Eldor A.; McCallum, K. J.
Date Issued:1964
Format:born digital; articles
The radioactivity of naturally occurring C14 in soil humus when compared to the C14 activity of a standard of recent origin (carbon dating) can be used to estimate the mean residence time of the soil humus in studying ...
Plant components and soil organic matter
Author(s):Paul, Eldor A.
Date Issued:1970
Format:born digital; articles
Large amounts of cellulose, aromatics, and proteinaceous compounds are introduced into the geochemical carbon pool as products of biological activity, or by economic and public health endeavors. Industrial wastes, pesticides, ...
Organic carbon dynamics in grassland soils. 1. Background information and computer simulation
Author(s):Paul, E. A.; Van Veen, J. A.
Date Issued:1981-05
Format:born digital; articles
The decomposition rates of 14C-labelled plant residues in different parts of the world were characterized and mathematically simulated. The easily decomposable materials, cellulose and hemicellulose, were described as being ...
Organic C dynamics in grassland soils. 2. Model validation and simulation of the long-term effects of cultivation and rainfall erosion
Author(s):Paul, E. A.; Voroney, R. P.; Van Veen, J. A.
Date Issued:1981-05
Format:born digital; articles
The amounts of organic matter in native prairie and in an adjacent cultivated field were compared with the output from a simulation model describing organic matter dynamics. The effects of past and possible future soil ...
Isolation of saprophytic basidiomycetes from soil
Author(s):Harris, David; Thorn, R. Greg; Reddy, C. Adinarayana; Paul, Eldor A.
Date Issued:1996-11
Format:born digital; articles
A method with the combined advantages of soil particle washing, selective inhibitors, and an indicator substrate was developed to isolate saprophytic basidiomycetes from soil. Organic particles were washed from soil and ...
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 ...
