Resources Flow and Nutrients Balance Analysis: Nutrients Flow and Their Impact on Soil Fertility Management Girmay Gebresamuel

Ethiopia is believed to have a considerable land resource for agriculture. This potential land reserve needs to be carefully identified, evaluated and used so that rational policies can be developed for their exploitation. The challenge of Ethiopian agriculture is not only of enhancing production to meet the increased food demands of the expanding population, but also the judicious use of soils so that their productivity is sustained in the foreseeable future. This book addresses the key to the development of sustainable agriculture, i.e. management of soil fertility. It presents complete pictures of how various landscape positions can be best managed under widely different socio-economic conditions. This book serves as an excellent reference for professionals preparing for a career in agricultural soil fertility management. Its features include: (1) Addresses soil fertility problem of development countries; (2) Describe and evaluate soil and nutrient management practices that either impair or sustain soil productivity and environmental quality; (3) Describe nutrient response pattern, fertilizer use efficiency, and the economics involved in fertilizer use.
