The article 3.4 of the Kyoto Protocol acknowledges agriculture soils as a potential sink for soil organic carbon (SOC). To estimate
current and potential SOC on a broad scale for these potential sin...
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...
