| Research Abstract |
A rockwool based nutrient dripping culture system for tomato was used as a model to clarifychanges in GHG emissions (CO_2, N_2O, and CH_4) from the rhizosphere. The points of the results are as follows: 1. The GHG emissions were highly dependent on the environmental conditions,such as temperature, irradiation, and fertilization. 2. The changes in GHG emission duringthe culture were almost the same between the rockwool culture and a traditional soilculture, although the total GHG emission was basically larger in the soil culture thanin the rockwool culture. 3. Changes in micro floras and the amounts were not correlatedwith the changes in N_2O emission. In particular, we established a continuous and real-timemeasurement system for N_2O emission, and newly discovered a very quick response of theN_2O emission to the fertilization (i.e., The N2O emission began to increase at least within10 to 15 min and peaked around 30 to 60 min from the beginning of each nutrient supply,and backed to the background level at most within 7 h after the end of the supply).
