説明

Digging a shallow well in a damp rice-field for the purpose of pumping up the surplus water therein, we surveyed the ground water level and exercised an experiment on the effects on the second crops and on the physical properties of the soil therein which are caused by controling the ground water level. As the result of the above experiment, we found that the physical properties of the soil can greatly be improved due to the remarkable development of the aggregate formation and of permeability of the soil, and furthermore we could make crops varying according to the depths of the ground water level even in the damp ricefield where no crop could be expected in the past.
