WebSummaryWe conducted a study to investigate the role of aggregates in the stabilization of residue- and root-derived C in an illitic Mollisol and a kaolinitic Oxisol under the following treatments: (i) incorporated residue, (ii) growing plants, and (iii) both incorporated residue and growing plants. WebFor example, a Mollic (diagnostic) horizon found in a Mollisol might be 50 cm thick and include an Ap, A, AB, B/A, and a Bw horizon, provided that all five of these genetic horizons meet the color, base saturation (non-acid saturation), ... silicate clay accumulation in an argillic horizon (argi), gleyed B horizon (aquic).

A vertisol, or vertosol, is a soil type in which there is a high content of expansive clay minerals, many of them known as montmorillonite, that form deep cracks in drier seasons or years. In a phenomenon known as argillipedoturbation, alternate shrinking and swelling causes self-ploughing, where the soil material consistently mixes itself, causing some vertisols to have an extremely deep A … Web1 jun. 2000 · Total Fe and Al content increases as soil particle size decreases, from 4.3 and 13.3 wt. % in the <2-mm size fraction to 8.5 and 22.8 wt. % in the clay fraction (<2 μm), … Web10 aug. 2024 · (1) Background: The preservation of soil organic carbon (SOC) by soil aggregates (SA) is a key mechanism for the stability of the soil carbon (C) pool.
