Book Description
Soil organic matter (SOM) is the primary determinant of soil functionality. Soil organic carbon (SOC) accounts for 50% of the SOM content, accompanied by nitrogen, phosphorus, and a range of macro and micro elements. As a dynamic component, SOM is a source of numerous ecosystem services critical to human well-being and nature conservancy. Important among these goods and services generated by SOM include moderation of climate as a source or sink of atmospheric CO2 and other greenhouse gases, storage and purification of water, a source of energy and habitat for biota (macro, meso, and micro-organisms), a medium for plant growth, cycling of elements (N, P, S, etc.), and generation of net primary productivity (NPP). The quality and quantity of NPP has direct impacts on the food and nutritional security of the growing and increasingly affluent human population. Soils of agroecosystems are depleted of their SOC reserves in comparison with those of natural ecosystems. The magnitude of depletion depends on land use and the type and severity of degradation. Soils prone to accelerated erosion can be strongly depleted of their SOC reserves, especially those in the surface layer. Therefore, conservation through restorative land use and adoption of recommended management practices to create a positive soil-ecosystem carbon budget can increase carbon stock and soil health. This volume of Advances in Soil Sciences aims to accomplish the following: Present impacts of land use and soil management on SOC dynamics Discuss effects of SOC levels on agronomic productivity and use efficiency of inputs Detail potential of soil management on the rate and cumulative amount of carbon sequestration in relation to land use and soil/crop management Deliberate the cause-effect relationship between SOC content and provisioning of some ecosystem services Relate soil organic carbon stock to soil properties and processes Establish the relationship between soil organic carbon stock with land and climate Identify controls of making soil organic carbon stock as a source or sink of CO2 Connect soil organic carbon and carbon sequestration for climate mitigation and adaptation

Book Description
Soil organic matter (SOM) is a highly reactive constituent of the soil matrix because of its large surface area, high ion exchange capacity, enormous affinity for water due to hygroscopicity, and capacity to form organo-mineral complexes. It is an important source and sink of atmospheric CO2 and other greenhouse gases depending on climate, land use, soil and crop management, and a wide range of abiotic and biotic factors, including the human dimensions of socioeconomic and political factors. Agroecosystems are among important controls of the global carbon cycle with a strong impact on anthropogenic or abrupt climate change. This volume of Advances in Soil Sciences explains pedological processes set-in-motion by increases in SOM content of depleted and degraded soils. It discusses the relationship between SOM content and critical soil quality parameters including aggregation, water retention and transport, aeration and gaseous exchange, and chemical composition of soil air. The book identifies policy options needed to translate science into action for making sustainable management of SOM as a strategy for adaptation to and mitigation of climate change. Features: Relates soil organic matter stock to soil processes, climate parameters, vegetation, landscape attributes Establishes relationships between soil organic matter and land use, species, and climate Identifies land use systems for protecting and restoring soil organic matter stock Links soil organic matter stock with the global carbon cycle for mitigation of climate change Part of the Advances in Soil Sciences series, this volume will appeal to agricultural, environmental, and soil scientists demonstrating the link between soil organic matter stock and provisioning of critical ecosystem services for nature and humans.

Book Description
Rodale was founded on the belief that organic gardening is the key to better health both for us and for the planet, and never has this message been more urgent. Now, with Organic Manifesto, Maria Rodale, chairman of Rodale, sheds new light on the state of 21st century farming. She examines the unholy alliances that have formed between the chemical companies that produce fertilizer and genetically altered seeds, the agricultural educational system that is virtually subsidized by those same companies, and the government agencies in thrall to powerful lobbyists, all of which perpetuate dangerous farming practices and deliberate misconceptions about organic farming and foods. Interviews with government officials, doctors, scientists, and farmers from coast to coast bolster her position that chemical-free farming may be the single most effective tool we have to protect our environment and, even more important, our health.

Book Description
Soil organic matter - the product of on-site biological decomposition - affects the chemical and physical properties of the soil and its overall health. Its composition and breakdown rate affect: the soil structure and porosity; the water infiltration rate and moisture holding capacity of soils; the diversity and biological activity of soil organisms; and plant nutrient availability. This document concentrates on the organic matter dynamics of cropping soils and discusses the circumstances that deplete organic matter and their negative outcomes. It then moves on to more proactive solutions. It reviews a "basket" of practices in order to show how they can increase organic matter content and discusses the land and cropping benefits that then accrue.--Publisher's description.

Book Description
Finalist for the PEN/E. O. Wilson Literary Science Writing Award "A call to action that underscores a common goal: to change the world from the ground up." —Dan Barber, author of The Third Plate For centuries, agricultural practices have eroded the soil that farming depends on, stripping it of the organic matter vital to its productivity. Now conventional agriculture is threatening disaster for the world’s growing population. In Growing a Revolution, geologist David R. Montgomery travels the world, meeting farmers at the forefront of an agricultural movement to restore soil health. From Kansas to Ghana, he sees why adopting the three tenets of conservation agriculture—ditching the plow, planting cover crops, and growing a diversity of crops—is the solution. When farmers restore fertility to the land, this helps feed the world, cool the planet, reduce pollution, and return profitability to family farms.

Book Description
A modern classic of the new agrarianism "Chris Smaje...shows that the choice is clear. Either we have a small farm future, or we face collapse and extinction."—Vandana Shiva "Every young person should read this book."—Richard Heinberg In a groundbreaking debut, farmer and social scientist Chris Smaje argues that organizing society around small-scale farming offers the soundest, sanest and most reasonable response to climate change and other crises of civilisation—and will yield humanity’s best chance at survival. Drawing on a vast range of sources from across a multitude of disciplines, A Small Farm Future analyses the complex forces that make societal change inevitable; explains how low-carbon, locally self-reliant agrarian communities can empower us to successfully confront these changes head on; and explores the pathways for delivering this vision politically. Challenging both conventional wisdom and utopian blueprints, A Small Farm Future offers rigorous original analysis of wicked problems and hidden opportunities in a way that illuminates the path toward functional local economies, effective self-provisioning, agricultural diversity and a shared earth. Perfect for readers of both Wendell Berry and Thomas Piketty, A Small Farm Future is a refreshing, new outlook on a way forward for society—and a vital resource for activists, students, policy makers, and anyone looking to enact change.

Book Description
Rainfall levels are rarely optimal, but there are hundreds of things you can do to efficiently conserve and use the water you do have and to reduce the impact of drought on your soil, crops, livestock, and farm or ranch ecosystem. Author Dale Strickler introduces you to the same innovative systems he used to transform his own drought-stricken family farm in Kansas into a thriving, water-wise, and profitable enterprise, maximizing healthy cropland, pasture, and water supply. Ranging from simple, short-term projects such as installing rain-collection ollas to long-term land-management planning strategies, Strickler’s methods show how to get more water into the soil, keep it in the soil, and help plants and livestock access it.
