“…Thus, the interaction between crop rotation and pH and rainfall synergistically promoted SOC growth. The most significant effect of crop rotation on SOC enhancement was observed when the pH was in the middle value of 6−8 and rainfall was in the 600−1000 mm range [12]. The pH range of soils in the Sushui River Basin is 7.5−9; when the pH value is in the 6−8 range, it is favorable for biodiversity.…”

“…The pH range of soils in the Sushui River Basin is 7.5−9; when the pH value is in the 6−8 range, it is favorable for biodiversity. This can promote crop growth to improve straw return and maintain soil aggregate stability, thereby promoting SOC sequestration [12][13][14][15][16]. When the average rainfall is 600-1000 mm, crop rotation can significantly promote SOC growth [12].…”

“…Some papers on soil organic carbon spatial mapping have highlighted that adding cropping system factors can improve the accuracy of spatial mapping [3,8,11]. As one of the principles of conservation agriculture, crop rotation has received widespread attention because of its ecological functions, such as mitigating soil degradation and slowing down Land 2024, 13, 859 2 of 14 SOC loss [12]. In a meta-analysis conducted by Zheng et al [12], crop rotation was shown to be able to enhance SOC in general as it can keep the ground covered, increase soil biodiversity, and boost the number of agglomerates and, in turn, organic C content [13][14][15][16].…”

“…Soil C sequestration mainly occurs through crop root secretions, and monocrop cultivation has a shorter duration of soil C sequestration than rotational grain cultivation [19]. However, the enhancement is affected by climate, soil properties, and other agronomic practices [12,20,21], indicating that SOC changes under the influence of crop rotation are strongly spatially heterogeneous. Understanding the interactive effects of crop rotation and environmental factors on SOC is crucial for enhancing C sequestration potential, alleviating climate stress, and improving soil fertility to enhance farm productivity [22].…”

Enhancing soil organic carbon (SOC) content in farmland is crucial for soil quality maintenance and food security. However, the relationship between crop rotation and SOC sequestration remains unclear. We used sample data on SOC, collected in September of every year, from cultivated land for quality monitoring from 2017 to 2021, combined with spatially extracted planting system information, and focused on the effects of wheat–maize crop rotation on SOC in the Sushui River Basin. An analysis of variance (ANOVA) indicated that the SOC content was only significantly different between wheat monoculture and maize monoculture. Among the three cropping systems, wheat–maize rotation did not show absolute superiority. The Geodetector analysis showed that the planting system dominated the spatial distribution of soil organic carbon (p = 0.05), but its explanatory factor was only 5%, and the explanatory power was significantly improved after interaction with other factors. Geographically weighted regression showed that wheat–maize rotation had a trade-off effect with elevation and synergistic effects with rainfall and pH. It displayed a synergistic effect with temperature in the southwest and a trade-off effect in the northeast. The degrees of trade-offs and synergy varied spatially among all interacting factors. We focused on the spatial heterogeneity of soil organic carbon in a small watershed, and the results had scientific significance for the layout of planting systems according to local conditions and the improvement in soil organic carbon levels.

This study explored the efficacy of soil aggregate indices in quantifying soil structural development, utilizing 5‐year field experiment data from the Southeastern United States. The experiment utilized a split‐plot design with cover crops (native vegetation as control, cereal rye (Secale cereale L.), winter wheat (Triticum aestivum), hairy vetch (Vicia villosa), and mustard (Brassica rapa) plus cereal rye as the main factor and fertilizer source (no fertilizer as control, inorganic fertilizer with phosphorus, potassium, and elemental sulfur, and poultry litter) as the secondary factor. Aggregate size fractions were determined using the wet‐sieving method, and aggregate stability index (ASI), mean weight diameter (MWD), geometric mean diameter (GMD), and fractal dimension (FD) were calculated to assess soil structural stability. Main effects results indicated that cereal rye (55.11%) and poultry litter (50.97%) exhibited the highest ASI values. The highest MWD, GMD, and FD were observed under mustard plus cereal rye (1.187 mm), cereal rye (0.462 mm), and hairy vetch (2.573), respectively. Principal component analysis revealed that cover crops significantly improved soil aggregate structure and stability, overcoming limitations of sole fertilization practices. Regression analysis suggested that ASI, MWD, and GWD positively correlated with soil organic carbon, whereas FD negatively correlated with MWD, GMD, and ASI. Principal component analysis exhibited that FD decreased with increasing soil organic carbon, ASI, MWD, and GMD, demonstrating that lower FD values indicate enhanced soil aggregation and structure. Assessed indices, FD included, effectively gauged soil structural stability. These metrics should be prioritized in managerial decisions to support soil productivity and health in agricultural systems.
