| The effects of the addition of decomposing forest litter, collected from Podzolic soil organic layers (Oi, Oe and Oa) and Brown Forest soil Oe layers, on the amounts and composition of low molecular weight aliphatic carboxylic acids (LACAs) in soils were investigated by incubation experiments for 4 weeks. The total amounts of LACAs were greater at the beginning of incubation (384 to 1155 μmol kg-1), but decreased abruptly after 1 week, becoming relatively stable for a period of 1 to 4 weeks (299 to 377 μmol kg-1). The average amounts (without 0 weeks) of LACAs, especially acetic acid and citric acid, in soils incubated with forest litter under moderately moist conditions, were smaller than in the blank soil. Larger amounts of LACAs, especially formic acid,... |
