Through thorough research and practical trials, several significant findings have confirmed the effectiveness and sustainability of this innovative approach. The main goal of this thesis was to find a sustainable way to enhance soil fertility and crop yields in Algeria, especially in sandy and arid areas suffering from severe soil degradation. Traditional chemical fertilizers have proven to be unsustainable, leading to long-term soil 30 health issues and environmental damage. This study introduced an innovative organic-mineral fertilizer, addressing the urgent need for eco-friendly and sustainable agricultural practices.enMasters degree Thesis
