Restructuring alkaline floodplain soils: Straw-derived artificial humic acid enhances aggregate stability, carbon sequestration, and crop yield

Compacted alkaline soils in the historical Yellow River floodplain constrain hydraulic regulation, carbon stabilization, and crop productivity. We evaluated a nitrogen-enriched artificial humic acid (A-HA) synthesized from crop residues by supercritical ammonification in a two-ye...
