Summary

Abstract The contributions of winter rye (WR; Secale Cereale L.) roots and stubble to soil carbon (C) and nitrogen (N) cycling have often been overlooked. A key novelty of the current study is quantifying root and stubble‐derived C and N, along with nutrients allocation among plant parts across WR developmental stages. Treatments consisted of WR growth stage and plant parts. Post‐termination decomposition dynamics were evaluated for plant parts, with aerial residues either retained on the soil surface (no‐till) or incorporated into the soil (conventional tillage) systems. Although spring N application did not significantly affect biomass, total WR biomass increased from 2684 kg ha −1 at the vegetative stage to 5738 kg ha −1 at boot and 7964 kg ha −1 at heading, with progressive shift towar
