Conservation Agriculture


Book Description

In large parts of the developed and developing worlds soil tillage by plough or hoe is the main cause of land degradation leading to stagnating or even declining production levels and increasing production cost. It causes the soil to become more dense and compacted, the organic matter content to be reduced and water runoff and soil erosion to increase. It also leads to droughts becoming more severe and the soil becoming less fertile and less responsive to fertiliser. This book brings together the key notes lectures and other outstanding contributions of the I World Congress on Conservation Agriculture and provides an updated view of the environment and economic advantages of CA and of its implementation in diferent areas of the World.




No-tillage Seeding in Conservation Agriculture


Book Description

This book is a much-expanded and updated edition of a previous volume, published in 1996 as "No-tillage Seeding: Science and Practice". The base objective remains to describe, in lay terms, a range of international experiments designed to examine the causes of successes and failures in no-tillage. The book summarizes the advantages and disadvantages of no tillage and highlights the pros and cons of a range of features and options, without promoting any particular product.







Plowman's Folly


Book Description

Mr. Faulkner’s masterpiece is recognized as the most important challenge to agricultural orthodoxy that has been advanced in this century. Its new philosophy of the soil, based on proven principles and completely opposed to age-old concepts, has had a strong impact upon theories of cultivation around the world. It was on July 5, 1943, when Plowman’s Folly was first issued, that the author startled a lethargic public, long bemused by the apparently insoluble problem of soil depletion, by saying, simply, “The fact is that no one has ever advanced a scientific reason for plowing.” With the key sentence, he opened a new era.For generations, our reasoning about the management of the soil has rested upon the use of the moldboard plow. Mr. Faulkner proved rather conclusively that soil impoverishment, erosion, decreasing crop yields, and many of the adverse effects following droughts or periods of excessive rainfall could be traced directly to the practice of plowing natural fertilizers deep into the soil. Through his own test-plot and field-scale experiments, in which he prepared the soil with a disk harrow, in emulation of nature’s way on the forest floor and in the natural meadow, by incorporating green manures into its surface, he transformed ordinary, even inferior, soils into extremely productive, high-yield croplands.Time magazine called this concept “one of the most revolutionary ideas in agriculture history.” The volume is being made available again not only because farmers, ranchers, gardeners, and agriculturists demanded it, but also because it details the kind of “revolution” which will aid those searching for the fruits of the earth in the emerging nations.




Tillage Systems in the Tropics


Book Description

The objectives of this Bulletin are to collate up-to-date information on soil tillage requirements for soils in the tropics; to assess the impacts of different ways of tillage on soil, environment and crop productivity; and to outline criteria for developing environment-friendly and economically viable tillage techniques for sustainable use of soil and water resources




Sustainable Intensification


Book Description

Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.




Management of Carbon Sequestration in Soil


Book Description

This book addresses the importance of soil processes in the global carbon cycle.Agricultural activities considered responsible for an increase in CO2 levels in our atmosphere include: deforestation, biomass burning, tillage and intensive cultivation, and drainage of wetlands.However, agriculture can also be a solution to the problem in which carbon can be removed from the atmosphere and permanently sequestered into the soil. Management of Carbon Sequestration in Soil highlights the importance of world soils as a sink for atmospheric carbon and discusses the impact of tillage, conservation reserve programs (CRP), management of grasslands and woodlands, and other soil and crop management and land use practices that lead to carbon sequestration.




Food Security and Soil Quality


Book Description

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 tolerat

Managing Cover Crops Profitably (3rd Ed. )


Book Description

Cover crops slow erosion, improve soil, smother weeds, enhance nutrient and moisture availability, help control many pests and bring a host of other benefits to your farm. At the same time, they can reduce costs, increase profits and even create new sources of income. You¿ll reap dividends on your cover crop investments for years, since their benefits accumulate over the long term. This book will help you find which ones are right for you. Captures farmer and other research results from the past ten years. The authors verified the info. from the 2nd ed., added new results and updated farmer profiles and research data, and added 2 chap. Includes maps and charts, detailed narratives about individual cover crop species, and chap. about aspects of cover cropping.
