Book Description
Tropical Africa escaped from the glaciers that covered the temperate parts of the world during the Ice Age. The legacy is that most of the parent materials of the soils of tropical Africa are old, highly weathered and devoid of bases and phosphate-bearing minerals. Traditional farming systems which were relatively stable and sustainable relied on long fallow periods after one to two years of cropping to maintain the productive capacity of the soils. In recent times and especially in densely populated areas, a sizeable class of 'landless' farmers have begun to cultivate marginal lands or to invade the 'forest reserves' thereby exacerbating the problems of land and environ mental degradation. of soil fertility that will facilitate the production of adequate quantities of the principle Maintaining a level staples has become a major challenge to agricultural scientists in tropical Africa. To increase the nutrient supplying power of soils requires the inputs of fertilizers. These can be organic or inorganic. The efficiency with which these externally supplied inputs can increase agricultural production and reduce soil and environmental deterioration is dependent on the ability of scientists to determine the right types and quantities of the products to apply to each soil, crop and cropping system as well as the ability of farmers to acquire requisite farm manage ment skills.

Soil Fertility Management in Support of Food Security in Sub-Saharan Africa
Author: D. J. Greenland
Publisher: Food & Agriculture Org.
ISBN: 9789251045633
Category : Business & Economics
Languages : en
Pages : 70
Book Description
This publication reviews issues related to land degradation, with focus on problems of soil fertility management in sub-Saharan Africa. It highlights some successful experiences in the region, constraints and possible solutions specific to the major agro-ecological zones and the importance of the holistic and participatory approaches for soil productivity improvement. The need for action and collaborative efforts of all stakeholders, within the framework of ongoing initiatives, are emphasized. It is hoped that this document will contribute to increase awareness of senior specialists and policy-makers about the problems and alternative solutions towards enhanced and sustained soil productivity.

Lessons learned from Long-term Soil Fertility Management Experiments in Africa
Author: Andre Bationo
Publisher: Springer Science & Business Media
ISBN: 9400729383
Category : Technology & Engineering
Languages : en
Pages : 210
Book Description
This book elucidates the importance of long-term experiments in revealing evidence of soil fertility decline in Africa. An evaluation of experiences from on-going long-term experiments is given in broad detail. The first chapter explains the paradigm shift in soil fertility management then provides justification for long-term experiments before illuminating experiences from long-term experiments in East, West and Southern Africa. The second, sixth, eighth and ninth chapters give an in-depth account of crop management practices and soil fertility interventions in long-term trials within specific agro-ecological zones in West Africa. The rest of the chapters (chapter three, four, five and seven) address crop management, tillage practices and, organic and inorganic fertilizer applications in the context of long-term experiments in specific agro-ecological zones in East Africa.

Villages in the Future
Author: Detlef Virchow
Publisher: Springer Science & Business Media
ISBN: 3642565751
Category : Political Science
Languages : en
Pages : 410
Book Description
Life in rural communities is bound to change with historically unprecedented speed in the coming decades. How will this change be guided by local, national and global policies in order to enhance the livelihoods of rural inhabitants and to overcome the growing division of rural and urban areas? The contributions in this publication, ranging from scientific papers to short reports from practitioners, are grouped around 4 major themes: political and institutional frameworks to foster rural development; natural resources management; broadening the technological base of rural economies; and improved linkages between urban and rural areas. The overall message is unanimous: there is a promising future for the rural areas worldwide if adequate policies can be enforced and more efficient and fair institutions can be created.
