| Research Abstract |
To continuous monitoring soil respiration rate in filed condition where there is no commercial electric power supply, we developed a new machine with 6 sample cahngers. It is an urgent subject for us to devleop a new machine for measuring soil respiration in forests without any commercial electric power supply to contribute to estimate the net ecosystem production, net biomass production minus so-called soil respiration rate. The machine could run for one week with two car batteries and registered more than 1000 data set were automatically recorded. However, the size was far from a handy type but one chamber size was 50x50x15cm and main operation part was 50x80x25cm with 6kg. Therefore, it is rather difficult for us to use this system by single investigator but more than two persons will be needed to set them up at the study site. We could not complete the water-proof in the data logger part. Further improvement will be needed in this point for commercial use.
