The objectives of this study were to determine the amounts of soil organic matter (SOM) stored within surface soils of high mountain forests and how the SOM amounts are affected by aridity and altitud...
Quantitative and qualitative soil organic matter properties were observed in a specific large area experiment (Chernozem – Gross Enzersdorf, Austria) and in a medium-term field experiment (Cambisol – ...
In average samples of three sandy-loamy acid Cambisols from a South Bohemian area labile organic matters were determined by the permangate method modified by the dichromate method, and the rate consta...
Parameters evaluating soil organic matter quantity (organic C and N content) and quality (hot water extractable C content, aliphatic compounds, microbial biomass C content, basal respiration activity)...
The trends of carbon sequestration behaviour have been estimated for the most fertile soil type of Slovakia based on the prognosticated regional climate change scenario. The processes were modelled an...
Soil organic matter under different tillage and fertilisation systems of long-term fallow experiment established in 1958 in Prague was characterised in period of 1972–2004. This experiment consists of...
In eight samples of organic and organomineral surface horizons we studied the stability of soil organic matter in aerobic and anaerobic conditions expressed by the rate constant of its biochemical oxi...
To explore the effects of different fertilization regimes on soil organic matter (SOM) sequestration in a winter-soybean/corn rotation, a long-term field experiment was conducted in Anhui, China, from...
南京农业大学土壤学课件 Soil Organic Matter
Semi-arid areas comprise a large portion of the world’s agricultural crop land. These areas are characterised by high temperature and low rainfall which hinders soil organic matter accumulation.
Soil organic matter (SOM) is essential to all soil processes that have an impact on crop production and the environment. Soils of the semi-arid Mediterranean region are low in SOM due to environmental...
The type of tillage in arable soils affects porosity of the soil and in consequence the hydraulic conductivity. The accessibility and mobility of organic carbon in arable soils can differ depending on...
Because of the importance of soil organic matter (SOM) and wet aggregate stability (WAS) on soil quality, the maintenance of satisfactory levels of these parameters is an integral component of soil m...
Estimation of the influence of different farming systems on emission of greenhouse gases (methane and nitrous oxide) was the aim of the research. The research was conducted on the basis of a special f...
The aim of this study was to characterize soil organic matter in the Nature Reserve Žitavský wetland. The area is located on a fluvial plain of Žitava River. Soil pits were trenched o...
