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.

... Chisel point tines are suitable in low-residue cover situations. Although development of no-till planting machinery is constantly producing improvements and refinements (e.g., the 'Baker boot' inverted-T shaped opener [10]) the designs specifically for low-cost machines aimed at smallholder farmers are generally kept as simple as possible [11]. Manually operated jab planters are suitable for very small holdings and are available with both seed and fertilizer metering. ...

... The rotary blades ahead of the tines in strip tillage clear the standing stubble, reducing the risk of blockage by standing residue but loose heavy residue may still cause a problem. For four-wheel tractor minimum tillage planters, residue height should be adjusted relative to the minimum clearance height of tool bars and spacing between tines (Baker et al., 2007). With the VMP in strip tillage mode, stubble heights of wheat and rice of up to 50 cm have been managed. ...

... Conservation agriculture involves minimal soil disturbance, permanent residue cover, and diverse crop rotations. Permanent soil cover through the use of cover crops and crop residue mulch retention combined with reduced tillage is suggest to be the best management practice for improving nutrient cycles and soil organic matter restoration, increasing available soil water, and controlling erosion (Hobbs, 2007;Hobbs, Sayre, & Gupta, 2008;Reicosky & Saxton, 2007). Therefore, the N fertilization rate can be either reduced or eliminated, reducing the cost of N fertilization. ...
