| Research Abstract |
We calculated the distribution of water by using mathematical model implemented with drip irrigation and pitcher irrigation. Based on the calculation, condition of irrigation was evaluated by varying the strength and interval of irrigation. Then, we designed the sterilized Hele-Shaw soil column and prepared the small-scale water supplying equipment. With the Hele-Shaw soil column, chemotaxis and hydrotaxis of microbial community in soil before and after water saving irrigation were evaluated.
