Crop residue management and oxalate-extractable iron and aluminium explain long-term soil organic carbon sequestration and dynamics Hasselt University KU Leuven
The management of crop residues affects carbon (C)-sequestration. This study aimed to identify the interaction between residue management and soil properties on C-sequestration. The hypothesis was that larger silt and clay contents and larger residue inputs enhance C-sequestration. The soil was sampled in Belgium in long-term (≥15 years) cropping systems with grain maize, Zea mays L. (all stover (leaves and stalks) returned), silage maize (all ...
