Background and Aims Suitable N source supply is critical to improve plant growth and N uptake, but the importance of nitrate (NO 3 − ) for rice ( Oryza sativa L.) and microbiota is often neglected in acidic paddy soils where ammonium (NH 4 + ) is dominant. This study aimed to explore the differentia...
