Outline of Final Research Achievements

The study established the simple valuation system of soil physics characteristics using the plastic bottle, that was hence enable to use in the junior high school technology class as teaching tools while insufficient for agricultural techniques.
The improvement of drainage (vapor) in volcanic ashes soil was clarified that the mixing of the vermiculite by 25% or 50% was most suitable.
As a result of cultivating experiment of mizuna and cabbage under a different watering condition with these mixed soil, the improvement of soil drainage hasten the growth and decreased the growth decrements.
