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...

Dissolved organic carbon (DOC) losses from tile drains are an underquantified portion of the terrestrial carbon cycle. This is particularly important in the eastern corn belt where tile drainage domin...
The Influence of Clay Content, Organic Carbon and Land Use Types on Soil Aggregate Stability and Tensile Strength
Tensile strength GIS soil aggregate stability organic carbon clay content
2009/1/13
Soil tensile strength (TS) and aggregate stability (AS) values can be used as indicators of soil structural quality. The objective of this study was to determine the influences of land use types, soil...
