Liming Alters the Soil Microbial Community and Extracellular Enzymatic Activities in Temperate Coniferous Forests

چکیده

Soil acidification caused by anthropogenic activities adversely affects forest ecosystems altering soil pH, which is an important factor in quality and function. Liming one suggested way to solve this problem. This study was performed evaluate the effects of liming acidic soils determining microbial biomass, community structure, extracellular enzyme associated with carbon, nitrogen, phosphorus cycling. Lime treatment increased pH up 40%, significantly organic matter (OM) content at some sites, altered activity soil. With liming, biomass appeared be affected chemical properties soil, such as Ca2+, Mg2+, K+, exchangeable aluminum (Ale) levels, although there were no significant differences site level. Enzymatic found electrical conductivity (EC), Ale; acid phosphatase (AP) phenol oxidase (POX) lime treatment. AP decreased from 0.62 0.66, POX 1.75 3.00 part sites. The bacterial richness influenced a direct effect fungal changes K+ that not due structure OM, total nitrogen (TN), Ca2+; K+. In conclusion, environmental conditions can affect communities functions through or indirect processes, further changing ecosystem processes.

Fire Alters Vegetation and Soil Microbial Community in Alpine Meadow

Grassland fire, as an important ecological factor, is quite influential in determining the structural and functional stability of ecosystem. In this work, the fire-induced changes on the vegetation and soil microbial community were studied in alpine meadow. Microbial community composition was assessed by phospholipid fatty acid (PLFA) analysis, and functional diversity was determined by Biolog ...

Invariant community structure of soil bacteria in subtropical coniferous and broadleaved forests.

Soil bacteria may be influenced by vegetation and play important roles in global carbon efflux and nutrient cycling under global changes. Coniferous and broadleaved forests are two phyletically distinct vegetation types. Soil microbial communities in these forests have been extensively investigated but few studies have presented comparable data regarding the characteristics of bacterial communi...

Altitudinal variation in soil organic carbon stock in coniferous subtropical and broadleaf temperate forests in Garhwal Himalaya

BACKGROUND The Himalayan zones, with dense forest vegetation, cover a fifth part of India and store a third part of the country reserves of soil organic carbon (SOC). However, the details of altitudinal distribution of these carbon stocks, which are vulnerable to forest management and climate change impacts, are not well known. RESULTS This article reports the results of measuring the stocks ...
