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.

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.

Abstract: This paper examines whether the choice of crops is affected by climate in Africa. Using a multinomial logit model, the paper regresses crop choice on climate, soils, and other factors. The model is estimated using a sample of more than 7,000 farmers across 11 countries in Africa. The study finds that crop choice is very climate sensitive. For example, farmers select sorghum and maize-millet in the cooler regions of Africa; maize-beans, maize-groundnut, and maize in moderately warm regions' and cowpea, cowpea-sorghum, and millet-groundnut in hot regions. Further, farmers choose sorghum, and millet-groundnut when conditions are dry; cowpea, cowpea-sorghum, maize-millet, and maize when medium wet; and maize-beans and maize-groundnut when wet. As temperatures warm, farmers will shift toward more heat tolerant crops. Depending on whether precipitation increases or decreases, farmers will also shift toward drought tolerant or water loving crops, respectively. There are several policy relevant conclusions to draw from this study. First, farmers will adapt to climate change by switching crops. Second, global warming impact studies cannot assume crop choice is exogenous. Third, this study only examines choices across current crops. Future farmers may well have more choices. There is an important role for agronomic research in developing new varieties more suited for higher temperatures. Future farmers may have even better adaptation alternatives with an expanded set of crop choices specifically targeted at higher temperatures.

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.

Degradation of soils continues at a pace that will eventually create a local, regional, or even global crisis when diminished soil resources collide with increasing climate variation. It's not too late to restore our soils to a more productive state by rediscovering the value of soil management, building on our well-established and ever-expanding scientific understanding of soils. Soil management concepts have been in place since the cultivation of crops, but we need to rediscover the principles that are linked together in effective soil management. This book is unique because of its treatment of soil management based on principles—the physical, chemical, and biological processes and how together they form the foundation for soil management processes that range from tillage to nutrient management. Whether new to soil science or needing a concise reference, readers will benefit from this book's ability to integrate the science of soils with management issues and long-term conservation efforts.
