Abstract Agricultural management practices can affect soil aggregate stability and resistance to erosion. A four‐field experiment near Pontotoc, MS, investigated the integration effects of poultry litter inorganic fertilizer N with amendments winter cover crop on upland erodibility at 0‐ 15‐cm 15‐ 30‐cm depths in a no‐till corn system. Main plots were treated either or no crop, while sub‐plots received (PL1), (FR1), combinations these flue gas desulfurization gypsum lignite (PL2 FR2, respectively), alongside an unfertilized control. Soil indices determined conclusion study. Results exhibited that 0.25–0.053 mm aggregates (38.3%–54.6%) most prevalent among treatments depths. Winter resulted highest values mean weight diameter (MWD) geometric (1.4 0.57 mm, fractal dimension (FD) factor K lowest (1.81 0.08, respectively). Among fertilization treatments, alone MWD (1.5 mm) FD (1.8) (0.07). Spearman's correlation analysis random forest modeling jointly demonstrated >2 primary influencing erodibility. Overall, results emphasized combining crops enhanced erosion soils under system, offering sustainable agricultural sustainably improve health mitigate risks.

Abstract Applying biochar (BC) and integrating cover crops (CCs) into crop rotations may enhance soil health. However, studies on the combined effects of these practices physical health are scant. Therefore, this study evaluated BC, CC, their (BC + CC) application properties medium fine‐textured soils in Ohio. In fall 2020, 10 Mg ha −1 pine ( Pinus L.) wood chips derived BC was applied. Rye Secale cereale winter wheat Triticum aestivum were planted as CC 2021 2022, respectively. Soil properties: bulk density, penetration resistance (PR), water retention, wet aggregate stability assessed 2023. Note that 2 years CCs alone did not generate evident any soil's properties. adding improved some specific properties, with varying by texture. medium‐textured soil, reduced PR from 1.18 MPa unamended control to 0.89 at 7.5‐cm depth, while increased mean weight diameter 0.6 mm, reaching 4.1 mm compared for 0‐ 10‐cm depth. moisture retention field capacity 0.36 0.39 cm 3 −3 plant available 0.13 0.16 5‐cm The 32% 0.93 Overall, highlights potential combining improve health, paving way management practices.

ABSTRACT Changes in near soil‐surface traits with crop growth can strongly influence erosion processes during rainfall events and provide valuable insights for farmland management. This study explored how growth‐induced variations affect soil on gently sloping farmlands. A simulation experiment a intensity of 80 mm h −1 was carried out runoff plots (5 m × 1.4 m) filled clay loam slope gradients 5.24% 8.75% at five soybean stages (G1‐seeding, G2‐jointing, G3‐final flowering, G4‐grain forming, G5‐ripening). Near were measured, sediment samples collected measured. The results indicated that the variation time‐dependent showed weak to strong temporal variations. Overall, measured rates variations, first decreasing then increasing growing season. mean rate, concentration decreased by 8%–75%, 13%–92%, 5%–73%, respectively, comparison bare soil. Seasonal total volume, yield closely related changes growth. Linear or exponential functional relationships found between volume traits. reflects positive impact reducing provides theoretical guidance water conservation
