Assessing the amount of soil organic matter and soil properties in high mountain forests in Central Anatolia and the effects of climate and altitude
forest soil topographic conditions climate model semi-arid regions Turkey
2017/6/26
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...
Sorption of heavy metals in organic horizons of acid forest soils at low added concentrations
acidic soils adsorption desorption organic matter risk elements
2015/3/13
The individual adsorption/desorption of Cu, Pb, and Zn in six soil samples taken from organic horizons of acid forest soils is studied in batch experiments. These three metals were chosen because of t...
Interactive effects of arbuscular mycorrhizae and maize (Zea mays L.) straws on wheat (Triticum aestivum L.) growth and organic carbon storage in a sandy loam soil
Glomus caledonium rhizosphere acidification root-to-straw ratio soil enzyme straw return
2015/3/10
A pot experiment was conducted to study interactive effects of arbuscular mycorrhizae (AMs) and maize (Zea mays L.) straws on wheat (Triticum aestivum L.) growth and organic carbon (C) storage in a st...
Effect of agricultural lands afforestation and tree species composition on the soil reaction, total organic carbon and nitrogen content in the uppermost mineral soil profile
acidification afforestation carbon nitrogen soil reaction
2015/3/10
Forests occupy one third of the world’s land area and govern carbon (C) transfers and influence nitrogen (N) content in the biosphere. Afforestation leads to soil changes of specific dynamics, often a...
Soil organic carbon dynamics and its influence on the soil erodibility factor
agrotechnical erosion control measures soil erodibility factor soil erosion soil organic carbon
2015/3/5
The effect of erosion and erosion control measures on changes in the amount of organic matter in soil was studied. We investigated the influence of organic matter inputs into the soil on surface runof...
Simulation of soil organic carbon changes in Slovak arable land and their environmental aspects
agricultural management long-term simulation RothC model soil organic carbon soil quality
2015/3/5
One of the key goals of the Thematic Strategy for Soil Protection is to maintain and improve soil organic carbon (SOC) stocks. A decline of SOC stocks is politically perceived as a serious threat to s...
Modelling soil organic carbon changes on arable land under climate change – a case study analysis of the Kočín farm in Slovakia
arable land climate change Kocín farm Slovakia soil organic carbon
2015/3/3
We have estimated soil organic carbon and crop yield changes under distinct climate change scenarios for the Kočín farm in Slovakia. Two regional climate change scenarios, i.e. the A2 and B2 SRES...
Changes of soil organic matter under minimum tillage in different soil-climatic conditions
Cambisol Chernozem humus content and quality humus fractionation minimum tillage
2015/3/2
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 – ...
Influence of the degree of soil organic matter lability on the calcium carbonate equilibrium of soil water
calcium carbonate equilibrium degree of lability liming need soil organic matter soil water
2015/3/2
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...
Application of RothC model to predict soil organic carbon stock on agricultural soils of Slovakia
agricultural land RothC Slovakia soil organic carbon
2015/3/2
Soil organic matter (SOM) takes part in many environmental functions and, depending on the conditions, it can be a source or a sink of the greenhouse gases. Presently, the changes in soil organic carb...
The influence of long-term organic and mineral fertilization on soil organic matter

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)...
A CENTURY 5 model using for estimation of soil organic matter behaviour at predicted climate change
carbon sequestration CENTURY 5 model climate change modelling regional climate scenario
2015/1/30
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...
