We sprayed water (control, CK) and 3 concentrations (0.005, 0.025 and 0.100 g dry weight ml−1) of aqueous extracts on cover soil (beneath which the litter of 3 plants were buried) to determine the rates of litter decomposition and C and N release from 3 dominant native plants (Pinus massoniana Lamb., Schima superba Gardn. et Champ. and Castanopsis chinensis Hance). The extracts increased the litter decomposition rates and nutrients (C, N) release from P. massoniana but decreased these in C. chinensis and there were no effects on S. superba. The changes were variable in different forests and were dependent on the extracts concentration.
