Soil quality, leaf litter quality, and microbial biomass interactively drive soil respiration in a microcosm experiment

open access: yesSoil Organisms, 2021
Soil respiration plays a central role in global carbon dynamics, and small changes in the magnitude of soil respiration could have large impacts on atmospheric CO2 concentrations.

Biodegradation kinetics of monosaccharides and their contribution to basal respiration in tropical forest soils [PDF]

open access: yesSoil Science and Plant Nutrition, 2011
Low molecular weight (LMW) organic compounds in soil solution are easily biodegradable and could fuel respiration by soil microorganisms. Our main aim was to study the mineralization kinetics of monosaccharides using 14C-radiolabelled glucose. Based on these data and the soil solution concentrations of monosaccharides, we evaluated the contribution of ...

Basal Area Effects on Soil Respiration Rates of a Pinus densiflora Stand

open access: yesJournal of Agriculture & Life Science, 2016
This study was conducted to determine the relationship between stand and soil environmental factors, and soil respiration rates at various levels of basal area in a 40-year-old natural red pine(Pinus densiflora S. et Z.) stand in southern Korea. Soil respiration rates were measured monthly using an infrared gas analyzer system from six basal area ...

Response of soil fungi and biological processes to crop residues in no-tillage system

open access: yesPesquisa Agropecuária Tropical, 2016
Soil management and crop rotation can directly affect the soil microbial community. This study aimed at determining soil quality indicators and soilborne fungi in a no-tillage system. A randomized blocks design, in a 3 × 2 factorial arrangement, was used.

Drivers of inter-year variability of plant production and decomposers across contrasting island ecosystems [PDF]

open access: yes, 2012
Despite the likely importance of inter-year dynamics of plant production and consumer biota for driving community- and ecosystem-level processes, very few studies have explored how and why these dynamics vary across contrasting ecosystems.

Effect of Water Erosion on Soil Respiration Characteristics of Chernozem Topsoil

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2016
Soil respiration characteristics are an important indicator of the soil state. The aim of this study is to determine the effect of water erosion on soil respiration characteristics, in particular to determine whether erosion-damaged areas show ...
