Soil fertility and crop management are the two most important ingredients in modern agricultural activity. This text explores research in the area, which is driven by the need to spread cropping zones, to intensify and obtain higher yields, and to achieve better nutrient balance.

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.

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.

"Sustainable Soil Fertility Management mainly focuses on issues related to soil management at the field level, which is a prime concern for crop production that may be improved by adopting several sustainable management practices. Soil fertility is the capability of soil to sustain plant growth and optimize crop yield. This can be enhanced through the use of organic and inorganic fertilizers. Several techniques are suggested that enhance soil fertility and crop production while minimizing environmental impact. Soil fertility can be further improved by incorporating cover crops that add organic matter to the soil, which leads to improved soil structure and promotes a healthy, fertile soil; by using green manure or growing legumes to fix nitrogen from the air through the process of biological nitrogen fixation; and by microbes. Fertile soil contains all the major nutrients necessary to sustain basic plant nutrition (e.g., nitrogen, phosphorus, and potassium), as well as other nutrients needed in smaller quantities (e.g., calcium, magnesium, sulfur, iron, zinc, copper, manganese, boron, molybdenum, nickel). The book focuses on global strategies with a possible solution for managing the fertility of soil. The book covers soil science, soil fertility, crop production, soil sustainability, and soil management with a modern scientific approach that is helpful for researchers, the scientific community, academicians, business farmers and policymakers"--

Cover crops slow erosion, improve soil, smother weeds, enhance nutrient and moisture availability, help control many pests and bring a host of other benefits to your farm. At the same time, they can reduce costs, increase profits and even create new sources of income. You¿ll reap dividends on your cover crop investments for years, since their benefits accumulate over the long term. This book will help you find which ones are right for you. Captures farmer and other research results from the past ten years. The authors verified the info. from the 2nd ed., added new results and updated farmer profiles and research data, and added 2 chap. Includes maps and charts, detailed narratives about individual cover crop species, and chap. about aspects of cover cropping.

Soil fertility is the backbone of agricultural systems and plays a key role in determining food quantity and quality. In recent decades, soil fertility has decreased due to indiscriminate use of agrochemicals, and nations around the globe are now facing the challenge of increasing food production while sustainably maintaining soil fertility. Written by leading international scientists in the field, this book explores soil fertility management strategies, including agronomic, microbiological and soil-science based strategies. Highlighting the practices that can be incorporated into organic farming and discussing recent advances, it is a valuable resource for researchers wanting to broaden their vision and the scope of their investigations.

Sustainability of agricultural systems is a major global concern due to population growth and a number of environmental factors. This book addresses the key to the development of sustainable agriculture-management of soil fertility. Combining data from temperate and tropical regions, it presents a complete picture of how various soils can best be managed under widely different environmental conditions. Soil Fertility Management for Sustainable Agriculture is an excellent reference for environmental and agricultural professionals as well as a textbook for undergraduate and graduate students preparing for a career in agriculture or soil fertility management.

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.
