This book was released on 2012-12-06 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Fighting Poverty in Sub Saharan Africa The Multiple Roles of Legumes in Integrated Soil Fertility Management written by Andre Bationo and published by Springer Science & Business Media. This book was released on 2011-08-24 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Legumes play an important role in the cropping systems of sub Saharan Africa (SSA). Legumes are an important source of nutrition to both humans and livestock by providing the much needed protein, minerals, fibre and vitamins. The sale of legumes seed, leaves and fibre generates income for the marginalized communities especially women. Cultivation of legumes is essential for the regeneration of nutrient-deficient soils. By biologically fixing nitrogen (BNF) in the soil, legumes provide a relatively low-cost method of replacing otherwise expensive inorganic nitrogen in the soil. This enhances soil fertility and boosts subsequent cereal crop yields. Production of legumes in SSA is however; hampered by a number of constraints among them low and declining soil fertility, low soil pH, high salinity, drought and flooding, poor access to improved germplasm, diseases, pests and weeds. Farmers need to learn how to overcome these constraints if the full benefits of legumes are to be gained. This book presents a synthesis of research work on legumes and draws attention to the importance of legumes in integrated soil fertility management (ISFM) and poverty alleviation in SSA.

Available in PDF, EPUB and Kindle. Book excerpt: Can a continuous growth of agriculture be achieved in the sub-Sahara region without inducing irreversible damage to the ecosystem? Until now, doubts have been expressed as to the actual capacity of the soils to sustain a desirable increase of production which can match the requirements of a fast-growing population. Thirty years of investigation and a renewed comprehensive interpretation of research data on soil fertility show that a sustainable agriculture growth could be a practical possibility in a savannah region.

This book was released on 2001 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1998-01-01 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: World Bank Technical Paper No. 408. This report is a critical review of the technical, economic, and institutional constraints on improving soil fertility in Sub-Saharan Africa, and the actions recommended to address them. Action plans prepared for Ghana, Kenya, Malawi, and Mali examine the demand for and supply of mineral fertilizers, the exploitation of local mineral resources, the prevention of soil erosion and increasing soil-water retention, and soil fertility management using organic technologies and management practices.

Download or read book Soil and Soil Fertility Management Research in Sub Saharan Africa written by Henk Mutsaers and published by Taylor & Francis. This book was released on 2017-03-27 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Judicious soil fertility management is crucial for sustainable crop production and food security in sub-Saharan Africa (SSA). This book describes the various concepts and approaches underlying soil and soil fertility management research in SSA over the last fifty years. It provides examples of important innovations generated and assesses the position of research within the research-to-development continuum, including how innovations have been validated with the intended beneficiaries. Using the experience of the International Institute of Tropical Agriculture (IITA) as a case study, the authors analyse how processes, partnerships and other factors have affected research priorities, the delivery of outputs, and their uptake by farming communities in SSA. They evaluate both successes and failures of past investments in soil fertility research and important lessons learnt which provide crucial information for national and international scientists currently engaged in this research area. The book is organised in a number of chapters each covering a chronological period characterised by its primary research content and approaches and by the dominant research paradigms and delivery models.

This book was released on 2012-03-12 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book gives a detailed description of the application of DSSAT in simulating crop and soil processes within various Agro-ecological zones in Africa. The book, an output of a series of 3 workshops, provides examples of the application of DSSAT models to simulate nitrogen applications, soil and water conservation practices including effects of zai technology, phosphorus and maize productivity, generation of genetic coefficients, long-term soil fertility management technologies in the drylands, microdosing, optimization of nitrogen x germplasms x water, spatial analysis of water and nutrient use efficiencies and, tradeoff analysis. The minimum dataset requirements for DSSAT is discussed. This book arises from attempts to address the limited use of models in decision support by African agricultural (both soil scientist and agronomists) scientists.
