TL;DR: The authors in this article estimate that there are now some 106 million ha of arable and permanent crops grown without tillage in CA systems, corresponding to an annual rate of increase globally since 1990 of 5.3 million ha.

TL;DR: No-tillage farming offers a way of optimizing productivity and ecosystem services, offering a wide range of economic, environmental and social benefits to the producer and to the society as discussed by the authors.

TL;DR: In this paper, the practical application of three interlinked principles, namely, no or minimum mechanical soil disturbance, biomass mulch soil cover and crop speci cation, is discussed.

TL;DR: It is argued that standardization of research methodologies in no-tillage/conservation agriculture systems is needed based on a thorough description of the whole system so that results from different researchers and regions of the world can be logically compared.

TL;DR: In this article, the authors present the history of adoption of conservation agriculture and analyze reasons and actual regional trends for adoption to draw conclusions about future promotion of CA, and conclude that CA adoption has been intense in North and South America as well as in Australia and New Zealand, and more recently in Asia and Africa.
