Abstract

We evaluated natural seasoning rate of split logs from wet woody biomass for Japanese cedar (Cryptomeria japonica), konara oak (Quercus serrata) and sawtooth oak (Quercus acutissima) under some conditions differentiated in split length (30, 50, 90 cm) and drying circumstances (roofed or unroofed). Japanese cedar dried out more rapidly than oaks, drying under roofed circumstances was more effective than under unroofed circumstances and short length log enabled more rapid drying. In order to estimate the period of the natural seasoning of split logs, we constructed the formula for drying rate and initial mass.
