Abstract

Significant carbon losses from temperate grasslands on different soils may occur due to interannual variations in microclimatic patterns most notably due to increased drought and heat stress extremities. The investigated grassland ecosystems can take up 186 gC m -2year -1 or loose 73 gC m -2 year -1 depending on the precipitation supply and temperature. Increasing frequency of the above extremities on annual scale, also means that the region is among the vulnerable ones in terms of soil carbon loss and therefore potential occurrence of latent desertification. In addition to the micrometeorological factors the soil type have a great effect on the carbon balance of grasslands, due to greatly differing amount of precipitation needed to reach the field capacity ranges on the sandy and on the heavy clay soil, respectively.
