This book is a much-expanded and updated edition of a previous volume, published in 1996 as <em>No-tillage Seeding: Science and Practice</em>. 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. Topics added or covered in more detail in the second edition include:<br> � soil carbon and how its retention or sequestration interacts with tillage and no-tillage<br> � controlled traffic farming as an adjunct to no-tillage<br> � comparison of the performance of generic no-tillage opener designs<br> � the role of banding fertilizer in no-tillage<br> � the economics of no-tillage<br> � small-scale equipment used by poorer farmers<br> � forage cropping by no-tillage<br> � a method for risk assessment of different levels of machine sophistication<br>
