Effect of application of glucose, cellulose, and rice straw on nitrogen fixation (acetylene reduction and soil-nitrogen components) in anaerobic soil

Promotive and inhibitory effects of rice straw and cellulose application on rice plant growth in pot and field experiments

“…Generally BNF is enhanced by rice straw application in paddy fields, whereas cellulose application also stimulated BNF in soil (Magdoff and Bouldin 1970;Yoneyama et al 1977;Adachi et al 1989). In the previous report , we suggested that although microbial N 2 -fixation caused by organic matter application may increase the potential fertility of paddy soils, it was difficult to determine the effect of the benefits on grain yield directly.…”

“…In addition, biological nitrogen fixation (BNF) in paddy fields is generally enhanced by rice straw application. Evidences indicated the beneficial effect of rice straw incorporation on nitrogen fixation (acetylene reduction and soil-nitrogen components) and bacterial multiplication (Rice and Paul 1972;Yoneyama et al 1977;Matsuguchi 1979;Harper and Lynch 1984;Santiago-Ventura et al 1986;Ladha et al 1987;Adachi et al 1989). The enhancement of BNF by rice straw application could be considered for more efficient use of organic matter with the benefit of BNF and for the development of low-input technology for sustainable crop production.…”

Effect of Application of Rice Straw and Cellulose on Methane Emission and Biological Nitrogen Fixation in a Subtropical Paddy Field

“…1. The soil-ARA levels in the straw-and cellulose-amended plots during the rice cultivation period were rather low compared with those in laboratory experiments (Adachi et al 1989), but positive and similar to those reported by Ladha et al (1986). Cellulose incorporation (T5), however, stimulated soil-ARA during the early stage of rice growth, and a peak was obtained in March which thereafter decreased drastically.…”

“…At the early stage of plant growth, stimulation of soil-ARA peak in T5 could be associated with the decomposition of cellulose (Adachi et al 1989), whereas the maximum ARA was obtained in T3 (straw 10 t ha -1) at around heading. Sano et al (1981) and Ladha et al (1986Ladha et al ( , 1987 reported that maximum ARA was observed at the heading stage.…”

“…Ladha et al (1986) reported that straw application increased the shoot and total plant biomass at heading stage and total dry matter yield at harvest. Adachi et al (1989) reported the presence of a linkage between anaerobic cellulolytic bacteria and anaerobic N2-fixing bacteria during the decomposition of straw or cellulose and N enrichment by BNF.…”
