Soils  Land  and Life

Unbiased in approach, this book discusses the physical and chemical land and soil requirements needed to produce food and how economic, social, and political environments influence agricultural productivity. Presenting an array of soil and land properties and farming methods-ranging from slash and burn to highly technical practices-the author draws on his 40 years of worldwide experience to give readers a glimpse at the historical developments, natural resource concerns, and farming practices impacting human food production today.Presents the basics of how soils and land function and examines the impact of water, temperature and chemical elements on food production using minimal scientific terminology. Moves beyond explaining the physical and chemical requirements of human food production to encompass the economic, social and political factors that impact farming practices and overall productivity. Covers current farming methods being used in other countries, from the recent advances in farming on the poorest soils to the slash and burn farming in tropical jungles. Presents historical data to show how modern practices have reduced the cost of food and the amount of land needed to feed a growing population. Provides a strong foundation and makes later chapters on leaching, ground water contamination, floods and erosion easier to understand. Emphasizes the delicate balance of essential elements from the air and in the soil and presents the basic physical and chemical dynamics of the human food chain.Those looking for an easy to understand introduction to how and why various types of soil and land are used for human food production.

Soils and Food Security

Soil is essential to agriculture and a resource that cannot be replaced easily. Nevertheless, its importance to food production and the threats to its sustainability are often overlooked. This book, the 35th volume of Issues in Environmental Science and Technology, examines the current status of soils across the globe and their potential for food production to meet the needs of the World's population in the 21st Century. Threats, such as the degradation, pollution and erosion of soil are discussed, along with the possible consequences of climate change for soil and food production. As an ecosystem service, soil also serves to capture nutrients and sequester carbon, and these issues are discussed in the context of adding value to soil protection. The influence of modern agricultural techniques in enhancing soil productivity is also discussed. Throughout the book case studies support the discussion. Together with the books on Ecosystem Services, Sustainable Water, and Environmental Impacts of Modern Agriculture, this addition to the series will be essential reading for anyone concerned with the environment, whether as scientist, policy maker, student or lay reader.

For the Love of Soil

Learn a roadmap to healthy soil and revitalised food systems to powerfully address these times of challenge. This book equips producers with knowledge, skills and insights to regenerate ecosystem health and grow farm/ranch profits. Learn how to: - Triage soil health and act to fast-track soil and plant health-Build healthy resilient soil systems-Develop a deeper understanding of microbial and mineral synergies-Read what weeds and diseases are communicating about soil and plant health-Create healthy, productive and profitable landscapes.Globally recognised soil advocate and agroecologist Nicole Masters delivers the solution to rewind the clock on this increasingly critical soil crisis in her first book, For the Love of Soil. She argues we can no longer treat soil like dirt. Instead, we must take a soil-first approach to regenerate landscapes, restore natural cycles, and bring vitality back to ecosystems. This book translates the often complex and technical know-how of soil into more digestible terms through case studies from regenerative farmers, growers, and ranchers in Australasia and North America. Along with sharing key soil health principles and restoration tools, For the Love of Soil provides land managers with an action plan to kickstart their soil resource's well-being, no matter the scale."For years many of us involved in regenerative agriculture have been touting the soil health - plant health - animal health - human health connection but no one has tied them all together like Nicole does in "For the love of Soil"! " Gabe Brown, Browns Ranch, Nourished by Nature. "William Gibson once said that "the future is here - it is just not evenly distributed." "Nicole modestly claims that the information in the book is not new thinking, but her resynthesis of the lessons she has learned and refined in collaboration with regenerative land-managers is new, and it is powerful." Says Abe Collins, cofounder of LandStream and founder of Collins Grazing. "She lucidly shares lessons learned from the deep-topsoil futures she and her farming and ranching partners manage for and achieve."The case studies, science and examples presented a compelling testament to the global, rapidly growing soil health movement. "These food producers are taking actions to imitate natural systems more closely," says Masters. "... they are rewarded with more efficient nutrient, carbon, and water cycles; improved plant and animal health, nutrient density, reduced stress, and ultimately, profitability."In spite of the challenges food producers face, Masters' book shows even incredibly degraded landscapes can be regenerated through mimicking natural systems and focusing on the soil first. "Our global agricultural production systems are frequently at war with ecosystem health and Mother Nature," notes Terry McCosker of Resource Consulting Services in Australia. "In this book, Nicole is declaring peace with nature and provides us with the science and guidelines to join the regenerative agriculture movement while increasing profits."Buy this book today to take your farm or ranch to the next level!

Food Security and Soil Quality

Just five years ago, it was generally believed that the number of food insecure people in the world was on continuous decline. Unfortunately, widespread soil degradation along with resistance to recommended agronomic practices, and little attempt to restore degraded soils have conspired with significant droughts (in regions that could least tolerate them) to swell the ranks of the food insecure to over a billion people. The U.N. Millennium Development Goals’ intent to halve hunger by 2015 will not be realized. Food Security and Soil Quality brings together leading experts from across the world to provide a concise and factually supported exploration of the problem at hand and the critical steps needed to reverse it. Edited by Rattan Lal, and B.A. Stewart, two of the world’s most respected soil scientists, this important work — Assesses farming systems and food security in Sub-Saharan Africa, with special emphasis on land degradation Examines concerns with and approaches to soil quality management in Brazil and China Details achievable methods for improving soil quality for sustainable production Provides an insightful comparison of temporal changes in agricultural systems productivity in Punjab, India and Ohio Discusses the human dimension of the crisis including the influence of culture and spiritual beliefs Dr. Lal himself writes that despite the existence of scientific data on sustainable management of soil and water resources, problems of soil and environmental degradation have persisted and have been aggravated. And that these problems are rooted in land misuse and soil mismanagement. This book does provide policymakers and others with an understanding of the depth, complexity, and immediacy of this crisis, but more than a call to action, it also offers soil scientists working in this area with an understanding of what is being done and what needs to be done. Most importantly, this book helps us understand that the situation is not beyond remediation were we to act with great resolve and a sense of urgency. A tree's leaves may be ever so good, So may its bark, so may its wood; But unless you put the right thing to its root, It never will show much flower or fruit. — from Leaves Compared With Flowers, by Robert Frost
