| Research Abstract |
The objective of this research was to evaluate the effect and influence to water quality in the soil and surroundings by covering the soil surface with the crushed bamboo. And the soil organic matter dynamics was also simulated with the CENTURY model after the crushed bamboo was put into the soil at farmland. As the results, the mulching of about 2 cm thick crushed bamboo was effective to prevent soil water consumption and to decrease the environmental load. In this simulation, it seemed that the crushed bamboo of which thickness was less than 2 cm can be applied.
