- Abstract
Nitrogen (N) rhizodeposition is an important source of available nutrient for soil microorganisms, and also a crucial connection between plant, soil and microorganism. Recently, along with the in-depth studies on crop above-ground parts, increasing attention has been paid to crop below-ground parts, and N rhizodeposition is becoming one of the most important research fields. This paper briefly presented the latest research progress on N rhizodeposition both at home and abroad, including quantity assessment, influence factors, research and calculate methods, etc. for reference of relative research. Additionally, the paper put forward suggestions as strengening in the future the studies on rhizosphere sediment nitrogen and composition under field in-situ conditions, getting a better understanding of N rhizodeposition regulatory mechanism, and its synergy and mechanism with carbon rhizodeposition.
