心土露出 開墾地의 熟田化 促進을 爲한 綠肥作物 效用 比較에 關한 硏究 : Effect of different green manure crop on improving Physical-Chemical Properties of newly developed slope lands

다국어 초록 (Multilingual Abstract)

This experiment was carried out to study the changing of soil physical-chemical proper ties and a good green manure crop in order to make the mature field for shortage period.
The results obtained were summarized as follows;
1. In case of barnyard millet plot physical properties of soil was improved compare to control, including the bulk density and hardness.
2. Changing of soil chemical properties did not show certain tendency, but the only orgarnic matter's quantity was high in case of no lime treatment.
3. In case of lime treatment, fresh weight of lettuce was high. There was highly significant positive correlation between Root weight and Yields of lettuce.
4. the yield of green manure was highest in case of barnyard millet treatment. Barnyard millet seemed to be the best for green manure in newly reclaimed field.
