Microbial activity responses to water stress in agricultural soils from simple and complex crop rotations

Autor: J. Schnecker, D. B. Meeden, F. Calderon, M. Cavigelli, R. M. Lehman, L. K. Tiemann, A. S. Grandy

Publikováno v: SOIL, Vol 7, Pp 547-561 (2021)

Increasing climatic pressures such as drought and flooding challenge agricultural systems and their management globally. How agricultural soils respond to soil water extremes will influence biogeochemical cycles of carbon and nitrogen in these system

Stoichiometrically coupled carbon and nitrogen cycling in the MIcrobial-MIneral Carbon Stabilization model version 1.0 (MIMICS-CN v1.0)

Autor: E. Kyker-Snowman, W. R. Wieder, S. D. Frey, A. S. Grandy

Publikováno v: Geoscientific Model Development, Vol 13, Pp 4413-4434 (2020)

Explicit consideration of microbial physiology in soil biogeochemical models that represent coupled carbon–nitrogen dynamics presents opportunities to deepen understanding of ecosystem responses to environmental change. The MIcrobial-MIneral Carbon

Ramped thermal analysis for isolating biologically meaningful soil organic matter fractions with distinct residence times

Autor: J. Sanderman, A. S. Grandy

Publikováno v: SOIL, Vol 6, Pp 131-144 (2020)

In this work, we assess whether or not ramped thermal oxidation coupled with determination of the radiocarbon content of the evolved CO2 can be used to isolate distinct thermal fractions of soil organic matter (SOM) along with direct information on t

Soil microbial biomass and function are altered by 12 years of crop rotation

Autor: M. D. McDaniel, A. S. Grandy

Publikováno v: SOIL, Vol 2, Iss 4, Pp 583-599 (2016)

Declines in plant diversity will likely reduce soil microbial biomass, alter microbial functions, and threaten the provisioning of soil ecosystem services. We examined whether increasing temporal plant biodiversity in agroecosystems (by rotating crop

Representing life in the Earth system with soil microbial functional traits in the MIMICS model

Autor: W. R. Wieder, A. S. Grandy, C. M. Kallenbach, P. G. Taylor, G. B. Bonan

Publikováno v: Geoscientific Model Development, Vol 8, Iss 6, Pp 1789-1808 (2015)

Projecting biogeochemical responses to global environmental change requires multi-scaled perspectives that consider organismal diversity, ecosystem processes, and global fluxes. However, microbes, the drivers of soil organic matter decomposition and

Integrating microbial physiology and physio-chemical principles in soils with the MIcrobial-MIneral Carbon Stabilization (MIMICS) model

Autor: W. R. Wieder, A. S. Grandy, C. M. Kallenbach, G. B. Bonan

Publikováno v: Biogeosciences, Vol 11, Iss 14, Pp 3899-3917 (2014)

A growing body of literature documents the pressing need to develop soil biogeochemistry models that more accurately reflect contemporary understanding of soil processes and better capture soil carbon (C) responses to environmental perturbations. Mod
