Rainfall-driven processes and mechanisms driving water, carbon, and nitrogen loss in red soil sloping farmland in southern China

The dataset was generated from artificial rainfall experiments conducted in 2023 and 2024 on typical red-soil sloping farmland in southern China. Experiments took place at the Water-Saving Irrigation Experiment Center of Yunnan Agricultural University in Kunming, Yunnan Province. The data include carbon and nitrogen losses measured under simulated storm events for four tillage practices: plastic mulching, cross-slope ridge tillage, downslope ridge tillage, and conventional flat tillage.
