- 論文の詳細を見る
The acetylene-reducing activity of waterlogged soils was stimulated by the incorporation of rice straw at a relatively early stage of its decomposition. The straw caused a decrease in the inorganic nitrogen and in redox potential, making a favorable environment for N_2-fixing bacteria. But the stimulation of nitrogen fixation was observed only when the soils were kept waterlogged. Soils of Maahas and Banaue which had not been air dried showed a fairly high acetylene-reducing activity when rice straw was incorporated at a ratio of 0.5 or 1.0 percent. Also the rice stubble showed high acetylene-reducing activity when the stubbled soil was kept waterlogged.
