Effects of temperature, soil substrate, and microbial community on carbon mineralization across three climatically contrasting forest sites
How biotic and abiotic factors influence soil carbon (C) mineralization rate (RS) has recently emerged as one of the focal interests in ecological studies. To determine the relative effects of temperature, soil substrate and microbial community on Rs, we conducted a laboratory experiment involving reciprocal microbial inoculations of three zonal forest soils, and measured RS over a 61-day perio...
متن کاملCarbon mineralizability determines interactive effects on mineralization of pyrogenic organic matter and soil organic carbon.
Soil organic carbon (SOC) is a critical and active pool in the global C cycle, and the addition of pyrogenic organic matter (PyOM) has been shown to change SOC cycling, increasing or decreasing mineralization rates (often referred to as priming). We adjusted the amount of easily mineralizable C in the soil, through 1-day and 6-month preincubations, and in PyOM made from maple wood at 350 °C, th...
متن کاملElevated carbon dioxide alters the structure of soil microbial communities.
Pyrosequencing analysis of 16S rRNA genes was used to examine impacts of elevated CO(2) (eCO(2)) on soil microbial communities from 12 replicates each from ambient CO(2) (aCO(2)) and eCO(2) settings. The results suggest that the soil microbial community composition and structure significantly altered under conditions of eCO(2), which was closely associated with soil and plant properties.

Soil Microbial Substrate Properties and Microbial Community Responses under Irrigated Organic and Reduced-Tillage Crop and Forage Production Systems
Changes in soil microbiotic properties such as microbial biomass and community structure in response to alternative management systems are driven by microbial substrate quality and substrate utilization. We evaluated irrigated crop and forage production in two separate four-year experiments for differences in microbial substrate quality, microbial biomass and community structure, and microbial ...
