Walnut trees on the Tibetan Plateau have sustainable and nutritious characteristics. They grow naturally without use of any chemical fertilizers pesticides. Therefore, soil fertility walnut orchards is a key factor influencing yield quality. This experiment measured analyzed basic nutrient content, microbial biomass carbon (MBC), nitrogen (MBN), phosphorus (MBP), leaf indicators in five types representative orchard parent materials Gyaca County to clarify characteristics different their correlations with nutrients, providing basis for development plateau industry. The results showed that there were significant differences organic matter (SOM), total (TN), available contents, activity among materials. comprehensive representation levels soils as follows: gray-cinnamon calcareous alluvial > mountain meadow prairie brush soil. average MBC, MBN, MBP contents 368.8 mg/kg, 28.4 23.6 respectively, content topsoil (0–20 cm) was higher than subsoil (20–40 cm).

These findings are valuable future management orchards. types, improving actively applying nitrogen-rich should prioritized improve quality walnuts.

Evaluating soil quality (SQ) resulting from land management use impact is important for carbon (C) monitoring, sustainability and suitability. However, the data in less developed regions of Africa like Nigeria scarce, limiting our understanding at global scale. The study evaluated on Ebonyi State, Nigeria, a representative region Africa. Soil samples were collected 2021 resampled 2022 including five managements (FS = forest soil; GLS grass ACS alley cropping Soil; SDS sewage dump-soils; CCS continuously cultivated soil). physical chemical properties analyzed discussed. results shows that (bulk density, hydraulic conductivity, aggregate stability) significantly (P < 0.05) influenced by management. Moderate to high bulk very low conductivity (HC), stability observed across management, suggesting potential inhibition root penetration, poor aeration, water infiltration. Improved practices such as planting cover crops either re-grassing or addition crop residues could be adopted conservative options increasing encourage additional C. pH decreased with increase depth all uses both years. A higher 6.78 (slightly acidic) was seen lower mean 6.0 (moderately obtained 0-20 cm 2021. average nitrogen content rated "very high" (0.81 g kg

Watershed-scale management practices (WMPs) aimed at mitigating land degradation from soil erosion have been implemented across Ethiopia, including in the study area, yet their effect remains under-evaluated. A useful method to assess of WMPs involves comparing characteristics between micro-watersheds subjected different treatments. For this analysis, Urago and Mende Becho district, central were chosen for similar physical attributes, though only received government-initiated WMP interventions. This aims on properties under varying use types (LUTs) topographic positions (TPs) conserved versus non-conserved areas. To achieve objective, samples systematically collected three distinct LUTs upper, middle, lower TPs both (Urago) (Mende) micro-watersheds. The analysis revealed no significant differences. However, there indications minor improvements organic carbon (SOC), total nitrogen (TN), percent base saturation (PBS) micro-watershed. These are likely attributable interventions such as stone bunds, rehabilitation, improved drainage. Soil texture SOC levels strongly influenced by LUTs, showing better results pH, cation-exchange capacity (CEC), exchangeable Ca2+, PBS varied with TPs, higher values found elevations. Higher elevations had somewhat SOC, TN, Na+, potentially due specific replantation efforts, these increases not statistically significant. less effective lower-elevation farmlands, minimal impact combating degradation. underscores necessity comprehensive tailored sustainable approaches areas enhance quality.
