| Outline of Final Research Achievements |
Ｔhe crushed bamboo (CB) was made by mashing with high pressure. It has been used to cover the soil surface as the mulching stuff and soil improving materials. The objective of this study is to clarify the water saving effect of crushed bamboo mulching and to develop the new agricultural organic material like a rock wool (RW) medium. Two type of pot cultivation experiments were conducted. One was to evaluate the effect of covering the soil surface with the crushed bamboo. The other was to evaluate the possibility as the agricultural medium. As a result, the crushed bamboo reduced the total amount of the irrigated water 20% less than no mulching. Second, crushed bamboo medium showed high water retention close to rock wool and also showed high water permeability. As the result of the pot cultivation of tomato, there were no significant differences in the growth between crushed bamboo and rock wool medium. The use of bamboo will lead to conserve the rural environment.
