The role of plant nutrients for sustainable food crop production in sub-Saharan Africa edited by H van Reuler and W H Prins 1993 232pp ISBN 90 801673 12 Pbk VKP PO Box 443 2260 AK Leidschendam THE NETHERLANDS
Many people are concerned about the impact of the modern agricultural production techniques that will be needed to achieve increased food production in sub-Saharan Africa. One particular concern is the potential threat to the environment, particularly through indiscriminate fertilizer use. In order to make an assessment of the role of plant nutrients for sustainable food crop production in sub-Saharan Africa, a number of scientists were invited to review the subject from different angles. Their reports form the basis of this book, which was financed by FAO and VKP (Dutch Association of Fertilizer Producers). Emphasis is placed on the need to maximize the efficiency of fertilizer use, particularly since in many countries the subsidies on mineral fertilizers have been reduced. Whereas in industrialized countries environmental problems may be caused by the application of more nutrients than the plants need, in sub-Saharan Africa soil degradation is more likely to be caused by soil mining. Both systems are unsustainable but the consensus in this book is that the environmental consequences of continued low use of organic and mineral fertilizers are more devastating than those anticipated from increased fertilizer use. Part 1 of the book provides general information; Part 2 contains two case studies at country level, providing details from Malawi and Ethiopia. The book is intended for policy makers and all those with an interest in sustainable food crop production.
