Abstract
Wetland rice can be grown continuously with reasonable yield levels without N fertilizers. Long-term fertility trials in temperate and tropical regions have shown that about 50 kg N/ha is absorbed by every crop of rice grown without addition of N fertilizers (Koyama and App 1979). Quantitative assessment of this N gain is not yet satisfactory, but biological N2 fixation undoubtedly contributes to the N enrichment in paddy fields.
