Traditional cattle corralling practices are widely used by smallholder farmers in northern Benin as a strategy to improve soil fertility and increase crop yields. This study investigates the effects of cattle corralling on soil physico-chemical properties, maize yield, and soil carbon content. On-farm investigation was conducted and soil samples were collected from fields corralled every year and at intervals from one to seven years, alongside fields without corralling as control plots. Samples were submitted to laboratory analysis for macronutrients and carbon content assessment. Results show that fields corralled every year or in a recent year (C1) significantly enhance maize yields, reaching 2.5 to 2.77 t ha-1 compared to 1.60 t ha-1 in non-corralled fields. Additionally, soil organic matter (SOM) and soil organic carbon (SOC) levels were highest in fields corralled every year (EY), with SOM and SOC reaching 2.5% and 1.4%, respectively. The findings reveal a strong positive correlation between maize yield and key soil properties such as SOM, SOC, and potassium content, while an indirect correlation was observed between maize yield and soil pH and hydraulic conductivity. These results highlight the potential of cattle corralling to improve soil health, enhance crop yield, and contribute to sustainable agricultural practices and climate change resilience in semi-arid regions. The study suggests that continuous cattle corralling can be an effective tool for soil fertility enhancement and food security in northern Benin while enabling smallholder farmers contribute to climate change mitigation.
