Estimation of rate transfer from dead rootlets to organic matter in acid forest soils


Developments in agricultural and managed forest ecology4(24): 280-284
Estimation of rate transfer from dead rootlets to organic matter in acid forest soils
Transfer rate of dead beech and spruce rootlets to organic matter derived from roots, OMDR, was measured following successive coring of small plots without trees, and isolated by a ditch at the start of the experiment. In the case of spruce, very fine roots (d < 1 mm) and fine roots (1 < d < 5 mm) disappear within two years, with mean monthly transfer rates of S = 5.3 percent and S = 5.02 percent respectively. In case of beech rootlets, there is a lag time of nearly one year, and tailing after two years, S values were respectively S = 2.5 percent and S = 9.1 percent for very fine roots and fine roots. The author insists upon the difference which exists between transfer rate to OMDR and soil organic matter mineralization rate.
