“…Some field management practices, such as soil tillage, organic manures, and the use of crop residues were recommended to help sequester carbon (Saikia, Sharma, Thind, Sidhu, & Yadvinder, ). Therefore, the SOC content and soil properties are affected by different soil tillage and crop residues practices (Gupta Choudhury et al., ; Kumar et al., ; Lenka et al., ). In general, the SOC content and stocks increased in the upper soil layer under no‐tillage (Xu et al., ), but the SOC content and stocks decreased in the subsoil layer when compared with plow tillage (Hu, Shi, Wang, Gu, & Zhu, ).…”

“…() reported that macroaggregate stability decreased under no‐tillage conditions. However, some studies indicated that no tillage with surface crop residue retention (NT) treatments had higher ( P < .05) water‐stable macroaggregates in paddy field over the conventional tillage without crop residues treatment (Kumar et al., ; Nandan et al., ). Additionally, another study found that the no‐tillage and reduced‐tillage practices enhanced aggregate stability at 0–2.5 cm surface soil (Blanco‐Canqui 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.

“…R 0.25 , MWD and GMD are common indicators to reflect the size distribution of soil aggregates. Greater R 0.25 , MWD and GMD indicate higher stability of soil aggregate structure [25]. In this study, biochar amendment at 10 t•ha −1 significantly increased WR 0.25 , W-MWD and W-GMD under the treatments of conventional pure nitrogen application and 80% of conventional pure nitrogen application treatments as well as decreased the destruction of macroaggregates, which suggested that the positive effect of biochar combined with nitrogen fertilizer on increasing aggregate stability and improving soil structure in the purple soil.…”

Reduction of soil fertility and production efficiency resulting from excessive application of chemical fertilizers is universal in rapeseed-growing fields. The main objective of our study was to assess the effects of biochar combined with nitrogen fertilizer reduction on soil aggregate stability and rapeseed yield and to identify the relationship between yield and soil aggregate stability. A two-factor field experiment (2017–2019) was conducted with biochar (0 (C0), 10 (C10), 20 (C20) and 40 t·ha−1 (C40)) and nitrogen fertilizer (180 (N100), 144 (N80) and 108 kg N·ha−1 (N60)). Experimental results indicated that under N100 and N80 treatments, C10 significantly increased the macro-aggregates (R0.25), mean weight diameter (MWD) and geometric mean diameter (GMD) of soil water stable aggregate by 14.28%–15.85%, 14.88%–17.08% and 36.26%–42.22%, respectively, compared with C0. Besides, the overall difference of the soil water-stable aggregate content in 2–5 mm size range among nitrogen treatments was significant under the application of C10, which increased by 17.04%–33.04% compared with C0. Total organic carbon (TOC) in R0.25 of soil mechanical-stable aggregates was basically all increased after biochar application, especially in 0.25–1 mm and 1–2 mm aggregates, and had an increasing trend with biochar increase. C10 significantly increased rapeseed yield by 22.08%–45.65% in 2019, compared with C0. However, the reduction of nitrogen fertilizer reduced the two-year average rapeseed yield, which decreased by 11.67%–31.67% compared with N100. The highest yield of rapeseed was obtained by N100C10 in two consecutive years, which had no statistical difference with N80C10. However, the two-year yields of N80C10 were all higher than those of N100C0 with increase rate of 16.11%, and which would reduce 35.43% nitrogen fertilizer in the case of small yield difference, compared with the highest yield (2.67 t·ha−1) calculated by multi-dimensional nonlinear regression models. The regression analysis indicated R0.25, MWD and GMD had the strong positive associations with rapeseed yield, whereas percentage of aggregate destruction (PAD0.25) had a significant negative correlation with rapeseed yield. This study suggests that the application of biochar into upland purple soil could improve soil structure, increase the content of TOC in macro-aggregates under nitrogen fertilizer reduction as well as replace part of nitrogen fertilizer to achieve relatively high rapeseed yield.
