"Soil ecology is the study of interactions between the physio-chemical components of the soil and organisms living within the soil. Humans are highly dependent upon the soil ecosystem, which provides food, fibre, fuel and ecological services, such as the recycling of atmospheric gases. It is therefore important to understand the function and nature of the soil ecosystem in order to predict and mitigate the long-term consequences of present-day actions." "Soil Ecology & Management describes the organisms inhabiting the soil, their functions and interactions and the dimensions of human impact on the activity of soil organisms and soil ecological function. Chapters cover basic soil characteristics and biogeochemical cycling, key soil flora and fauna, community-level dynamics (soil foodwebs) and the ecological and pedological functions of soil organisms."--Jacket.

Over the past three decades, governments at the local, state, and federal levels have undertaken a wide range of bold innovations, often in partnership with nongovernmental organizations and communities, to try to address their environmental and natural resource management tasks. Many of these efforts have failed. Innovations, by definition, are transitory. How, then, can we establish new practices that endure? Toddi A. Steelman argues that the key to successful and long-lasting innovation must be a realistic understanding of the challenges that face it. She examines three case studiesùland ma

Major tree crops contribute substantially to the economy of many developing countries on the Asian, African and Latin American continents. For example, coffee is the main revenue earner for Kenya. This book provides a comprehensive review of the agronomy, botany, taxonomy, genetics, chemistry, economics, and future global prospects of a range of crops that have great food, industrial and economic value such as cocoa, coffee, cashew, oil palm and natural rubber. Discusses the major tree crops of great economic value to the developing worldThe author is an eminent

The relationships between soils, microbes and humans are of crucial relevance in the tropics, where plant stress and microbial activity are exacerbated. This volume of Soil Biology presents the living component of tropical soils, showing how it is shaped by environmental conditions and emphasizing its dramatic impact on human survival and well-being. Following an introduction to the specificities of tropical soils and of their microbial communities, the biological aspects of soil management are examined, dealing with land use change, conservation and slash-and-burn agriculture, the restoration of hot deserts, agroforestry and paddy rice cultivation. As they are of particular relevance for tropical agriculture, symbioses of plants and microbes are thoroughly covered, as are the biodegradation of pesticides and health risks associated with wastewater irrigation. Lastly, traditional soil knowledge is discussed as a key to our sustainable presence in this world.
