The influence of residue quality on soil organic C (SOC) retention has been called into question. A field experiment in Northeast Thailand, which contrasting residues were applied yearly for 13 yr, was used to determine quantities, locations, and stability SOC the matrix identify parameters affecting stabilization a tropical sandy‐textured soil. Total (TOC) content highest intermediate‐quality tamarind ( Tamarindus indica L.) at 3.58 g kg −1 (intermediate N, lignin, polyphenol contents),...
Abstract Against the background of current understanding dissolved organic carbon (DOC) adsorption onto clay surfaces, it remains unclear if bulk DOC or its fractions contribute to microaggregate formation in top layers coarse‐textured soils. We therefore investigated effects long‐term inputs biochemically contrasting residues on chemical characteristics and vertical distribution a Ultisol. During 2007–2008, samples were extracted from soil profiles residue quality field experiment initiated...
