“…In the present study, there was a significant difference in size class of soil aggregates under different soil tillage treatments, where each size class of soil aggregates under the CT, RT, and NT treatments were higher ( P < .05) than that under the RTO treatment in both years, as was also reported by Zhang et al. (). The reason for this could be due to the different mechanisms of effects (soil microbial activities, soil particles, and soil moisture content) on soil aggregation of crop residues and soil tillage practices (Lenka et al., ).…”

The effects of different tillage practices on soil organic carbon (SOC), soil aggregation, soil fulvic acid (C‐FAF), soil humic acid (C‐HAF), and soil humin (C‐HUM) contents at 0–5, 5–10, and 10–20 cm layers under double‐cropping rice (Oryza sativa L.) fields in southern China were explored. The experiment included four tillage treatments: conventional tillage and crop residues incorporation (CT), rotary tillage and crop residues incorporation (RT), no‐tillage and crop residues incorporation (NT), and rotary tillage without crop residues as a control (RTO). The results showed that SOC content under RT and CT treatments were significantly higher than that of RTO treatment. The percentage of soil aggregates of <0.001 mm, 0.005–0.001 mm, and 0.01–0.005 mm at 0–5, 5–10, and 10–20 cm layers under CT treatment were significantly higher than that of RTO treatment. The C‐HUM, C‐FAF, and C‐HAF contents were increased by combined application of tillage with crop residues practices. The results showed that C‐HUM, C‐FAF, and C‐HAF contents under CT and RT treatments were significantly higher than those under the RTO treatment at 0–5, 5–10, and 10–20 cm layers. As a result, it is an appropriate soil practice for increasing SOC content, soil aggregation, and humic substances under double‐cropping rice fields in southern China under conventional tillage and rotary tillage.

“…These uncertain responses of yield have dampened local farmers' enthusiasm for recycling organic materials to their fields (Hijbeek et al, ; Oelofse et al, ). In practice, crop yield responses are location specific because they depend on local management procedures (Das et al, ; Zhang et al, ). Integrated management practices can strengthen recycling effects on productivity to achieve sustainable intensification.…”

“…These physicochemical characters, however, showed opposite effect on aggregateassociated humic acids and humins. Another long-term field experiment was carried out in China (8-years field experiment) showed that humic substances promoted structural stability binding silt + clay fractions to form secondary microaggregates and then larger aggregates (Zhang et al, 2018).…”
