Abstract
Silvopastoral systems, which integrate trees, forage grasses, and livestock, are increasingly recognized as a sustainable land-use approach due to their ecological and economic benefits. This study investigates the relationship between soil physico-chemical characteristics and microbial dynamics under four treatments: Acacia leucophloea, Guinea grass, a combination of both, and an open plot. Soil samples were collected at 0–30 cm depth and analyzed for parameters including pH, electrical conductivity (EC), bulk density, porosity, soil organic carbon (SOC), microbial populations, and soil respiration rate. The combined treatment of A. leucophloea + Guinea grass exhibited the most favorable soil conditions, with the highest pH (7.1), EC (0.32 dS m?¹), porosity (51.7%), SOC (0.96%), and microbial activity. Microbial populations, particularly actinomycetes and soil respiration rates, were also maximized in this treatment, indicating improved microbial functioning and nutrient cycling. These results highlight the superior ecological function of integrated silvopastoral systems over monoculture or bare plots, underscoring their potential for soil health restoration and sustainable livestock production.
