Analysis of peat soil organic carbon, total nitrogen, soil water content and basal respiration: Is there a ‘best’ drying temperature?

Geoderma, 2021
Soil needs to be dried in order to determine water content, soil organic carbon content (SOC) and total nitrogen content (N). Water content is commonly measured using standard methods that involve drying temperatures of 105–110 °C. Recommended drying temperatures differ for the determination of SOC and N.

Drained organic soils under agriculture — The more degraded the soil the higher the specific basal respiration

Geoderma, 2019
Abstract Drained peatlands are hotspots of carbon dioxide (CO2) emissions from agricultural soils. As a consequence of both drainage-induced mineralisation and anthropogenic mixing with mineral soils, large areas of former peatlands under agricultural use underwent a secondary transformation of the peat (e.g. formation of aggregates).

The biochar effect on soil respiration and nitrification

Plant, Soil and Environment, 2018
Soil microorganisms play a main role in the nutrient cycle and they also play an important role in soil health. This article studies the influence of three rates of biochar (0.5, 1 and 3%) in comparison with control (0 biochar) in two different soils ...

Application of compost in spruce forests: effects on soil respiration, basal respiration and microbial biomass

Forest Ecology and Management, 2002
Compost from separated organic household waste contains considerable amount of nutrients such as N, P, K, Mg and Ca and may be used for amelioration of degraded forest soils. Our objective was to assess the effect of compost application on soil respiration, soil basal respiration and soil microbial biomass of two mature Norway spruce plantations in ...

Soil Microbial Biomass, Basal Respiration and Enzyme Activity of Main Forest Types in the Qinling Mountains

PLoS ONE, 2013
Different forest types exert essential impacts on soil physical-chemical characteristics by dominant tree species producing diverse litters and root exudates, thereby further regulating size and activity of soil microbial communities. However, the study accuracy is usually restricted by differences in climate, soil type and forest age. Our objective is

Response of mycorrhizal, rhizosphere and soil basal respiration to temperature and photosynthesis in a barley field

Soil Biology and Biochemistry, 2007
Abstract The mycorrhizal, rhizosphere and basal components of soil respiration were partitioned in a barley field experiment with the main objective of determining the controlling effects of photosynthetic activity and temperature on soil respiration sources.

Thinning effects on soil and microbial respiration in a coppice-originated Carpinus betulus L. stand in Turkey

iForest - Biogeosciences and Forestry, 2016
Effects of thinning on soil respiration and microbial respiration were examined over a 2-year period (2010-2012) in a coppice-originated European hornbeam (Carpinus betulus L.) stand in Istanbul, Turkey.

Effect of fungicides on soil respiration, microbial community, and enzyme activity: A global meta-analysis (1975–2024)

Ecotoxicology and Environmental Safety
Fungicides effectively prevent and control crop diseases caused by microorganisms; however, they also unintentionally affect soil microorganisms and enzyme activity.

Soil respiration across a permafrost transition zone: spatial structure and environmental correlates [PDF]

Biogeosciences, 2017
Soil respiration is a key ecosystem function whereby shifts in respiration rates can shift systems from carbon sinks to sources. Soil respiration in permafrost-associated systems is particularly important given climate change driven permafrost thaw ...

Physical, chemical, and biological properties of soil under soybean cultivation and at an adjacent rainforest in Amazonia [PDF]

Revista Ambiente & Água, 2015
Land-use change in the Amazon basin has occurred at an accelerated pace during the last decade, and it is important that the effects induced by these changes on soil properties are better understood.
