Abstract:

This study examines the comparative analysis of soil fertility and nutrient dynamics in two secondary forests Unizik Conservation Forest and Orebe Village Forest located in Awka North and South Local Government Areas of Anambra State, Nigeria. These forests are critical for biodiversity conservation and ecosystem restoration, particularly in the face of increasing deforestation and land-use changes. Through soil sampling and standard laboratory procedures, the research assesses soil properties to evaluate their potential for regeneration and long-term sustainability. Key soil parameters, including nitrogen, phosphorus, potassium, organic matter, and exchangeable acidity, were analyzed. Results reveal significant differences in nutrient availability and soil properties between the two forests. Amansea Forest exhibited higher nutrient levels and organic carbon, while Unizik Forest demonstrated better water-holding capacity and soil structure. These variations reflect differences in vegetation, soil management practices, and environmental conditions, highlighting the need for tailored conservation strategies to support forest regeneration and long-term sustainability. Future studies should focus on long-term monitoring of soil nutrient dynamics and the impact of climate change on soil fertility in secondary forests.
