In view of the grave consequences of soil degradation on ecosystem
functions, food security, biodiversity and human health, this book
covers the extent, causes, processes and impacts of global soil
degradation, and processes for improvement of degraded soils. Soil
conservation measures, including soil amendments, decompaction,
mulching, cover cropping, crop rotation, green manuring, contour
farming, strip cropping, alley cropping, surface roughening,
windbreaks, terracing, sloping agricultural land technology (SALT),
dune stabilization, etc., are discussed. Particular emphasis is
given to soil pollution and the methods of physical, chemical and
biological remediation of polluted soils. This book will lead the
reader from the basics to a comprehensive understanding of soil
degradation, conservation and remediation.
Soils are neither good nor bad, but some have inherent or acquired
characteristics that may or may not suit our intended use.
Unsuitable characteristics are considered to be soil problems, soil
constraints or soil limitations. Only twelve percent of global land
is right for agricultural production without much limitation. Some
soils have severe limitations for crop production. These soils are
so called 'problem soils'. Many of them do not have enough
fertility to be productive; some are arid and saline; some are very
sandy and dry; and some are wet and waterlogged for most of the
growing season. The global demand for food, wood, fuel, fiber,
medicine and other plant products for the 7.2 billion current world
population has created such an immense pressure on global soil
resources that even the most fertile soils are losing their
productive capacity. We are being compelled to bring more and more
unsuitable or marginally suitable soils under cultivation. Unless
innovative and integrated soil, crop and environmental management
practices are adopted for their improvement and sustainable use,
further degradation is inevitable. This book, Management of Soil
Problems, identifies the problems and discusses management options
in a smooth and reader-friendly style. It will be useful for
students and professionals of soil science, agriculture, forestry,
geography and environmental sciences.
Forest soil characteristics are not only unique but their
interpretation also differs from cropland soils. Just as there are
diverse forest types, there are many soil variants that need
different management. Today, forest plantations are being
intensively managed for profitable timber, pulpwood and energy
production. Site selection, species selection, site productivity
evaluation, silvicultural treatments, and soil amendments need
crucial soil information. This book provides a comprehensive
overview of the physical, chemical and biological properties of
forest soils and their implications on forest vegetation. Topics
discussed include: major forest types of the world and their
associated soils; forest biomass and nutrient dynamics; organic
matter turnover and nutrient recycling; forest soil disturbance;
forest soil and climate change; and forest soil management and
silvicultural treatments.

Aimed at taking the mystery out of soil science, Soils: Principles,
Properties and Management is a text for undergraduate/graduate
students who study soil as a natural resource. Written in a
reader-friendly style, with a host of examples, figures and tables,
the book leads the reader from the basics of soil science through
to complex situations, covering such topics as: the origin,
development and classification of soil physical, chemical and
biological properties of soil water and nutrient management
management of problem soils, wetland soils and forest soils soil
degradation Further, the ecological and agrological functions of
soil are emphasized in the context of food security, biodiversity
and climate change. The interactions between the environment and
soil management are highlighted. Soil is viewed as an ecosystem
itself and as a part of larger terrestrial ecosystems.
