The Microbial Efficiency‐Matrix Stabilization (MEMS) framework integrates plant litter decomposition with soil organic matter stabilization: do labile plant inputs form stable soil organic matter? (2013, background): “, 2008), microbes degrade plant litter with an initial higher N concentration more quickly (Hobbie, 2005).”
Microbial nitrogen limitation increases decomposition. (2007, background): “…another laboratory incubation survey that varied N availability (Wang et al. 2004), the most comprehensive field survey of decomposition to investigate the effects of litter and exogenous N on decomposition suggested inconsistent responses of decomposition to the two sources of N (Hobbie 2005).”
Contrasting effects of glucose, living roots and maize straw on microbial growth kinetics and substrate availability in soil (2009, background): “Not only the C/N ratio and soil properties, but also physiological attributes of the decomposer community such as substrate utilization efficiency (Hobbie, 2005; Magid et al., 2006), apparently determine the N effect on soil respiration.”
Changes in litter quality induced by N deposition alter soil microbial communities (2019, background): “Therefore, N-deposition 111 can influence decomposition processes through altering both litter composition and 112 intra-specific chemical quality (Hobbie, 2005; Knorr et al., 2005).”
Nitrogen additions and microbial biomass: a meta-analysis of ecosystem studies. (2008, background): “However, fungi and bacteria may not necessarily be limited by the same elements that limit plants (Hobbie 2005).”
Interspecific differences in wood decay rates: insights from a new short‐term method to study long‐term wood decomposition (2012, background): “Initial wood nutrient content (N, P and C ⁄N) was non-significantly related to WD T1 ⁄ 2, confirming that, while initial wood nutrient content generally matters for decomposition (Weedon et al. 2009), its influence on wood decomposition is rather complex, like in leaf litter (e.g. Hobbie 2005).”
Nitrogen addition stimulates forest litter decomposition and disrupts species interactions in Patagonia, Argentina (2011, background): “, 2008), which could explain why litter decomposition in forests with higher soil N background availability might respond less to N fertilization than in forests with lower N availability (Hobbie, 2005).”
Soil health in agricultural systems (2008, result): “…noted, however, that the results of experiments on this effect are equivocal: although a majority of results indicate the above effect, in a significant minority added inorganic nitrogen has either a neutral or even an inhibitory effect on the decomposition of low-N plant materials (Hobbie 2005).”
Factors controlling decomposition rates of fine root litter in temperate forests and grasslands (2014, background): “10, 07745 Jena, Germany e-mail: esolly@bgc-jena.mpg.de S. Boch Institute of Plant Sciences and Botanical Garden, University of Bern, Altenbergrain 21, 3013 Bern, Switzerland E. Kandeler : S. Marhan Institute of Soil Science and Land Evaluation, University of Hohenheim, Emil-Wolff-Str.”
Functional guild classification predicts the enzymatic role of fungi in litter and soil biogeochemistry (2015, methodology): “Assays were conducted at pH 4.5 to match litter pH in the field (Hobbie, 2005) and to select for extracellular enzymes (Sinsabaugh, 2010).”
Linkages between plant functional composition, fine root processes and potential soil N mineralization rates (2009, methodology): “The aim of our study was to investigate how plant functional composition affected root mass loss, root detritus N dynamics and soil N mineralization rates towards improved understanding of ecosystem N cycling.”
Litter decay rates are determined by lignin chemistry (2012, background): “However, N differences between these plants were small (3.5 lg N/mg stem tissue) and natural plants with this level of variation in N content often have similar rates of litter decay (e.g., Hobbie 2005; Melillo et al. 1982).”
Decay rates of leaf litters from arbuscular mycorrhizal trees are more sensitive to soil effects than litters from ectomycorrhizal trees (2015, background): “This finding supports previous studies that have found litter decomposition rates to be positively correlated with litter N concentrations (Melillo, Aber & Muratore 1982; Aerts 1997; Hobbie 2005; Cornwell et al. 2008), presumably because at low N concentrations, N availability limits microbial C use”
