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...
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...
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...

2014/10/28
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...
Using the DNDC model to compare soil organic carbon dynamics under different crop rotation and fertilizer strategies
crop yield fertilization croplands
2014/10/23
Soil organic carbon (SOC) plays a vital role in determining soil fertility, water holding capacity and susceptibility to land degradation. On the Chinese Loess Plateau, a large amount of crop residues...
