Effects of cultivation on the organic matter of grassland soils as determined by fractionation and radiocarbon dating
Contributor:Martel, Y. A.; Paul, Eldor A.
The effects of cultivation on the net mineralization of carbon and nitrogen in a lacustrine Brown clay (Sceptre) and two Orthic Black soils on glacial till (Oxbow) were assessed with the aid of fractionation and radiocarbon ...
Does physical protection of soil organic matter attenuate temperature sensitivity?
Contributor:Conant, Richard T.; Paul, Eldor A.; Six, Johan; Plante, Alain F.
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 ...
Role of soil characteristics on temperature sensitivity of soil organic matter, The
Contributor: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.
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 ...
Influence of nitrogen on the decomposition of crop residues in the soil, The
Contributor:Lueken, H.; Hutcheon, W. L.; Paul, Eldor A.
Additions of mineral nitrogen accelerated the initial decomposition rate of incorporated wheat straw, alfalfa hay and glucose when added to two soils differing widely in organic matter content. However, in the more advanced ...
Microbial responses to multi-factor climate change : effects on soil enzymes
Contributor:Steinweg, J. Megan; Dukes, Jeffery S.; Paul, Eldor A.; Wallenstein, Matthew D.
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 ...
Sensitivity of organic matter decomposition to warming varies with its quality
Contributor:Steinweb, Megan; Six, Johan; Plante, Alain F.; Paul, Eldor A.; Parton, William J.; Haddix, Michelle L.; Drijber, Rhae A.; Conant, Richard T.
The relationship between organic matter (OM) lability and temperature sensitivity is disputed, with recent observations suggesting that responses of relatively more resistant OM to increased temperature could be greater ...
Experimental warming shows that decomposition temperature sensitivity increases with soil organic matter recalcitrance
Contributor:Haddix, Michelle L.; Conant, Richard T.; Steinweg, J. Megan; Six, Johan; Paul, Eldor A.; Plante, Alain F.
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 ...
