Additional Information

The project was funded by the GIZ Soil Health Program of Ethiopia. We would like to thank Dr Steffen Schulz (GIZ) for facilitating the funding and for his involvement during the whole exercise. We greatly appreciate Steffen’s encouragement to the team, his enthusiasm and contribution to the sustainable improvement of soil health and agricultural productivity by supporting research and development in Ethiopia. The project was also benefited with partial support from Africa RISING (Africa Research in Sustainable Intensification for the Next Generation), a program financed by the United States Agency for International Development (USAID) as part of the United States Government’s Feed the Future Initiative. Thanks to the Ethiopian Institute of Agricultural Research (EIAR), especially Mr Gebreyes Gurum and Dr Tesfaye Shimber, for contributing to the success of the project. We are equally grateful for the work of our colleagues from EIAR and other institutions who reviewed the literature and presented their results at relatively short notice. Finally, sincere thanks to all the participants who attended the two-day workshop (1–2 December 2016), contributed to the presentations and made valuable comments and suggestions; and to Addisu Asfaw, for note taking during the workshop.

Abstract

More than 80% of the Ethiopian population is dependent on agriculture, which contributes about 50% of the country’s gross domestic product (GDP) and more than 80% of its export earnings. Although the agricultural sector is the engine of economic growth and the country has designed an “Agriculturalled Industrialization”, the agricultural sector is still characterized by severe soil erosion, high levels of nutrient mining, low use of external inputs, low productivity and limited capacity to respond to environmental shocks. Thus, the country is grappling with a daunting challenge: produce more food for a fast-growing population on low fertility soils on land owned by poor smallholder farmers who are unlikely to afford adequate input use. To address these challenges, several efforts are being made since the 1960s to assess the potential effects of various sources of organic and mineral fertilizers on crop yield and soil fertility status of the differing farming systems in the country...
