Thesis Abstract

Abstract
This thesis investigates the assessment of soil fertility and crop productivity in various land use systems to enhance sustainable agricultural practices. The study aimed to analyze the impact of different land use practices on soil fertility and crop productivity, identify the challenges faced in maintaining soil fertility, and propose strategies to improve agricultural sustainability. Through a comprehensive literature review, this research explored the existing knowledge on soil fertility management, crop productivity, and the relationship between land use systems and soil health. A mixed-methods approach was employed to collect and analyze data, including soil sampling, crop yield assessments, and interviews with local farmers. The results revealed significant variations in soil fertility levels and crop productivity across different land use systems, highlighting the importance of tailored management practices. The research also identified key factors influencing soil fertility, such as soil organic matter content, nutrient availability, and microbial activity. Furthermore, the study assessed the limitations and challenges faced in maintaining soil fertility in diverse agricultural settings, including land degradation, nutrient depletion, and unsustainable farming practices. The findings from this study provide valuable insights into the complex interactions between land use systems, soil fertility, and crop productivity. Recommendations for improving soil fertility and enhancing agricultural sustainability are discussed, including the adoption of conservation agriculture practices, organic farming methods, and integrated nutrient management strategies. The significance of this research lies in its potential to inform policymakers, agricultural practitioners, and researchers on the importance of sustainable soil management practices in promoting food security and environmental conservation. By understanding the dynamics of soil fertility in different land use systems, stakeholders can implement targeted interventions to enhance crop productivity while preserving soil health for future generations. This thesis contributes to the growing body of knowledge on soil fertility assessment and agricultural sustainability, emphasizing the need for holistic approaches to address the challenges of modern agriculture in a changing climate.
