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.

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.

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.

It is becoming more relevant to explore soil biological processes in terms of their contribution to soil fertility. This book presents a comprehensive scientific overview of the components and processes that underpin the biological characteristics of soil fertility. It highlights the enormous diversity of life in soil and the resulting effects that management of land can have on the contribution of this diverse community to soil fertility in an agricultural context.

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.

Like all living things, plants require nutrient elements to grow. The Plant Nutrition Manual describes the principles that determine how plants grow and discusses all the essential elements necessary for successful crop production. The nutritional needs of plants that add color and variety to our visual senses are addressed as well. Altogether, nut

North American Agroforestry Explore the many benefits of alternative land-use systems with this incisive resource Humanity has become a victim of its own success. While we’ve managed to meet the needs—to one extent or another—of a large portion of the human population, we’ve often done so by ignoring the health of the natural environment we rely on to sustain our planet. And by deteriorating the quality of our air, water, and land, we’ve put into motion consequences we’ll be dealing with for generations. In the newly revised Third Edition of North American Agroforestry, an expert team of researchers delivers an authoritative and insightful exploration of an alternative land-use system that exploits the positive interactions between trees and crops when they are grown together and bridges the gap between production agriculture and natural resource management. This latest edition includes new material on urban food forests, as well as the air and soil quality benefits of agroforestry, agroforestry’s relevance in the Mexican context, and agroforestry training and education. The book also offers: A thorough introduction to the development of agroforestry as an integrated land use management strategy Comprehensive explorations of agroforestry nomenclature, concepts, and practices, as well as an agroecological foundation for temperate agroforestry Practical discussions of tree-crop interactions in temperate agroforestry, including in systems such as windbreak practices, silvopasture practices, and alley cropping practices In-depth examinations of vegetative environmental buffers for air and water quality benefits, agroforestry for wildlife habitat, agroforestry at the landscape level, and the impact of agroforestry on soil health Perfect for environmental scientists, natural resource professionals and ecologists, North American Agroforestry will also earn a place in the libraries of students and scholars of agricultural sciences interested in the potential benefits of agroforestry.

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.
