Soil Degradation and Restoration in Africa (Advances in Soil Science)
by Rattan Lal B. A. StewartSoil degradation is a widespread problem in Africa resulting in low agricultural productivity while demand for food continues to increase. Degradation is caused by accelerated erosion, acidification, contamination, depletion of soil organic matter and plant nutrients, and salinization. Food and nutritional security of the growing population of Africa can only be achieved if degraded soils are restored, and soils of agroecosystems are managed prudently and sustainably. This book describes the soils of Africa, processes of soil degradation, extent and severity of soil degradation, and the impacts of degradation processes on food and nutritional security.
Soil Ecology and Management
by Joann Whalen Luis SampedroSoil 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, fiber, 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 and 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 discuss basic soil characteristics and biogeochemical cycling, key soil flora and fauna, community-level dynamics (soil food webs) and the ecological and pedological functions of soil organisms. Unlike other soil biology and ecology textbooks, the authors also convey a better understanding of how human activities impact upon soil ecology in a section on ecosystem management and its effects on soil biota and provide a unique perspective on the utility of soil organisms.
Soil Ecology in Northern Forests
by Martin Lukac Douglas L. GodboldForest soils form the foundation that underpins the existence of all forests. This book encapsulates soil ecology and functioning in northern forests, focusing on the effects of human activity and climate change. The authors introduce the fundamental principles necessary for studying forest soils, and explain the functioning and mutual influence of all parts of a forest soil ecosystem. A chapter is dedicated to each of soil acidity and heavy metal pollution, elevated carbon dioxide, nitrogen deposition and climate change, highlighting the most important anthropogenic factors influencing forest soil functioning and how these soils are likely to respond to environmental change. With its unique view of the functioning of the soils found under temperate and boreal forests in today's rapidly changing world, this book is of interest to anyone studying forestry and forest ecology in European, North American and North Asian contexts.
Soil Emission of Nitrous Oxide and its Mitigation
by Rattan Lal David UssiriNitrous oxide gas is a long-lived relatively active greenhouse gas (GHG) with an atmospheric lifetime of approximately 120 years, and heat trapping effects about 310 times more powerful than carbon dioxide per molecule basis. It contributes about 6% of observed global warming. Nitrous oxide is not only a potent GHG, but it also plays a significant role in the depletion of stratospheric ozone. This book describes the anthropogenic sources of N2O with major emphasis on agricultural activities. It summarizes an overview of global cycling of N and the role of nitrous oxide on global warming and ozone depletion, and then focus on major source, soil borne nitrous oxide emissions. The spatial-temporal variation of soil nitrous oxide fluxes and underlying biogeochemical processes are described, as well as approaches to quantify fluxes of N2O from soils. Mitigation strategies to reduce the emissions, especially from agricultural soils, and fertilizer nitrogen sources are described in detail in the latter part of the book.

Soil Health Restoration and Management
by Ram Swaroop MeenaMeeting the food requirements of an ever-increasing population is a pressing challenge for every country around the globe. Soil degradation has a negative impact on food security by reducing the cultivated land areas, while at the same time the world population is predicted to increase to 9.2 billion in 2050. Soil degradation adversely affects soil function and productivity and degraded soils now amount to 6 billion ha worldwide. The major factors are salinization, erosion, depletion of nutrients due to exhaustive agricultural practices and contamination with toxic metal ions and agrochemicals, which reduces the activity of soil microbe. In addition, poor soil management also decreases fertility. As such, measures are required to restore the soil health and productivity: organic matter, beneficial microorganisms and nutrient dynamics can all improve the physical, chemical and biological properties of soil. Understanding the role of soil health restoration and management in sustainability and nutritional security calls for a holistic approach to assess soil functions and examine the contributions of a particular management system within a defined timescale. Further, best management practices in cropping systems are important in ensuring sustainability and food and nutritional security without compromising the soil quality and productivity potential. Rational soil management practices must allow environmentally and economically sustainable yields and restoration of soil health.

This book explores state-of-the-art techniques based on open sources software & R statistical programming and modelling in modern geo-computation techniques specifically focusing on the recent trends in data mining/machine learning techniques and robust modelling in soil resources. Soil and agricultural systems are an integral part of the global environment and human well‐being, providing multiple goods and services essential for people worldwide and crucial for sustainable development. Soil contamination is an environmental hazard and has become a big issue related to environmental health. The challenge of the twenty-first century is to reduce the contaminant load and bring it to below permissible level. The contamination is not only a problem affecting local environments at the place of occurrence but also spreading to other regions because of easy transportation of pollutants. This leads to direct and indirect contamination of land and aquatic systems, surface water and groundwater, inducing significant risks for natural ecosystems. In this context, the spatial modelling, prediction, efficient use, risk assessment, protection and management of soil resources in the agriculture system are the key to achieving sustainable development goals and ensuring the promotion of an economically, socially and environmental sustainability future.

Soil Health and Nutrition Management
A major challenge for agriculture and future crop production is the deterioration in soil health and fertility. We have large areas of barren land across the globe with degraded soil which can only be made fertile by applying proper nutrition and soil health management practices. It is crucial to protect soil health in order to feed the world's ever-growing population. Healthy soil is a dynamic ecosystem containing microbes that aid in the breakdown of organic materials and minerals, increasing the availability of plant nutrients (nutrient recycling) and enhancing soil quality and crop output. Healthy soil also helps mitigate the impact of climate change by maintaining nutrients and sequestering atmospheric carbon. This book summarizes the numerous components of soil health management including cutting-edge technologies such as genome editing and rhizospheric engineering, together with conventional techniques for preserving soil nutrients.
