Soil CO2 efflux in young Norway spruce stands with different silviculture practices

Abstract

Seasonal changes of soil CO2 efflux were investigated in two young Norway spruce stands with different silviculture practices (below and above thinning) during the 2010–2012 at the Ecosystem Station of Rájec – Němčice (the Drahanská vrchovina Highland, the Czech Republic). Soil CO2 efflux was almost about 20% higher in the plot with above thinning compared to the plot with bellow thinning. Soil CO2 efflux between the studied plots was significant in the studied years 2010 and 2012. Soil CO2 efflux was positively related to soil temperature in the both studied spruce plots. Silviculture practices had effect on soil CO2 efflux in studied young Norway spruce stand.
