In the paddy fields of the volcanic ash area, percolation water is generally large owing to the soil character in the area. These experiments were made in order to establish the method to control the excessive percolation in the permeable paddy fields of volcanic ash most economically and reasonably, as bentonite can be added economically and reasoaably to alluvial sandy percolative paddy fields.
