摘要: Abstract In this report we studied the effects of mechanical grinding paddy soils on nitrogen mineralization and bacterial number when were incubated under a submerged condition after grinding. Nitrogen was increased by soil samples as compared with those without The value (Nd-Nu)/Nu, where Nd is amount ammonia-nitrogen formed incubation disrupted Nu undisrupted soils, in good correlation clay/humus ratio. Although significant difference not observed between aerobic bacteria samples, higher anaerobic numbers found than ones. A also obtained amounts bacteria.
