The main motivation for writing this dissertation is a profound interest in developing sustainable soil fertility management systems for crop production. The lack of organic soil amendment technology as an alternative to inorganic soil management systems is a frequently mentioned question in research, conferences, seminars, meetings, and climate change forums. Within this background, the aims of the dissertation are (a) to evaluate the effect of manuring and crop rotation on potato productivity; (b) to assess the effect of organic treatments and crop rotation on the growth and yield of bread wheat; (c) to estimate the growth and biomass yield response of clover to the preceding crop and organic treatment; and (d) to investigate the efficacy of long-term organic soil fertilization and crop rotation on soil physico-chemical properties.

The book is divided into the introduction, materials and methods, result and discussion, summary, conclusion, and recommendation. The introduction emphasizes that soil-related challenges have become fundamental problems for Ethiopian agriculture and are a major reason for the slow growth of food production. Using organic fertilizer instead of overreliant on chemical fertilizer could be an imidate solution to further decrease soil fertility and crop yield. The methodology of the study states the research site description, treatment set-up, data collection, and method of analysis. The result and discussion part focus on the main research findings. The summary, conclusion, and recommendation part summarizes the main research output, draws conclusions, and gives full recommendations.

Many institutions have contributed to the success of these PhD studies. My gratitude goes to the Amhara Agricultural Research Institute (ARARI) for giving me the opportunity to pursue my PhD study and for providing full financial support through the project “Smallholder Farmers’s Strategies to Cope with Climate Change” (SMACC). My thanks also go to Adet Agricultural Research Center (AARC) for providing me with planting materials, vehicles, laboratory services, and a working environment during my stay at the center. The staff of ARARI and BDU are greatly acknowledged for their efforts to facilitate financial affairs during research execution and implementation. I would also like to acknowledge my funding agencies, “The Agricultural Research for Development (ARD) and Dimension of European Research Area (ERA),” for funding the project.
