Effects of experimental soil frost on the fine-root system of mature Norway spruce

Soil-frost events may influence the dynamics of fine roots and therefore affect root-derived C fluxes to the soil. We studied the impact of soil frost on the fine-root dynamics of Norway spruce (Picea abies [L.] Karst.) by a replicated snow-removal experiment in a mature forest in SE Germany. Snow r...

Description
Summary:Soil-frost events may influence the dynamics of fine roots and therefore affect root-derived C fluxes to the soil. We studied the impact of soil frost on the fine-root dynamics of Norway spruce (Picea abies [L.] Karst.) by a replicated snow-removal experiment in a mature forest in SE Germany. Snow removal in the three treatment plots reduced soil temperature significantly with minima
