Studying green manure in several returning methods to enhance soil fertility and crop benefits is a strong foundation for cropland nutrient management. However, how different types of manures their variable doses affect the efficacy applied manures, either buried or mulched, remain overlooked. The objective this study was optimize management maize biomass using five (white mustard, forest rye, fiddleneck, sufflower, pea) two (low, 5 g per pot, high, 10 pot), which were mulched before after sowing. Results revealed that total carbon content increased due treatments, representing 10% increase over control, particularly through w. mustard (10% cultivation) safflower pea (12% 11% cultivation control). Dry aboveground yields also improved across all variants, with yielding 18.4 g·plant−1 (compared 8.6 control), 16.4 g·plant−1, 17.8 g·plant−1. Green mulching generally acidified (pH 5.71 compared 6.21 except fiddleneck 6.39 at high dose manures. Carbon-mineralizing enzyme activities (dehydrogenase β-glucosidase) significantly by showing 22.6% 20.6% 24.5% 22.4% under doses. suggests partially decomposed mineralized may induce negative priming effect on carbon-mineralizing enzymes decrease C/N ratio soil. It emphasizes stoichiometry alongside characteristics such as ratio, are critical factors sustainable sequestration. These findings underscore need careful selection health carbon-storage outcomes.

Abstract Numerous studies have demonstrated the enhancement effects of organic amendment additions on soil carbon (SOC) accumulation in agroecosystems. However, different types stable SOC formation through belowground inputs remain poorly understood, especially under stress conditions. This study aims to investigate three types, namely lignin- (LDA), humus- (HDA), and vetch-derived (VDA) amendments, transformation process 13C-rhizodeposits into sodic soil. Our results showed that nitrogen (N) compounds amendments accounted for 0, 6.21, 11.37% LDA, HDA, VDA, respectively. Organic with low C/N ratios (HDA VDA) enhanced SOC, particularly mineral-associated (13C-MAOC). In addition, HDA VDA substantially decreased exchangeable sodium percentage (ESP) increased nutrient contents (e.g., total N phosphorus) compared providing more favorable environmental conditions both crop rhizosphere microbial growth.
