Exploration of nitrogen use efficiency and root-shoot-soil variation on the stoichiometric characteristics of carbon, nitrogen, phosphorous and potassium for winter wheat under various nitrogen treatments.

ABSTRACT:

Background

Nitrogen (N) addition has significant effects on grain yield and nutrient use efficiency (NUE) in farmland ecosystems, and the total carbon: nitrogen: phosphorus: potassium (TC:TN:TP:TK) stoichiometry in plants and soil is of great significance for improving plant productivity and nutrition. However, there is still uncertainty regarding the effects of N fertilizers on the stoichiometric characteristics of different root-shoot parts of winter wheat during growth progression.

Methods

'Fengdecunmai5' wheat was selected as the material for the positioning test field. Three N application treatments (0, 180 and 300 kg ha^-1, designated N0, N180 and N300) were designed to study the yield, NUE, and stoichiometric characteristics of TC, TN, TP and TK in each orga
