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. It 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: · soil carbon and how its retention or sequestration interacts with tillage and no-tillage · controlled traffic farming as an adjunct to no-tillage · comparison of the performance of generic no-tillage opener designs · the role of banding fertilizer in no-tillage · the economics of no-tillage · small-scale equipment used by poorer farmers · forage cropping by no-tillage · a method for risk assessment of different levels of machine sophistication.
