This book features four peer-reviewed reviews on zero/no-till cultivation.The first chapter assesses the effect of no-till (NT) practices on soil health. The chapter explores the wide range of research on the effects of NT on the physical, chemical, and biological properties of soils, as well as continuing challenges to address in NT research and practice.The second chapter reviews the role of no or minimum soil disturbance in Conservation Agriculture (CA) systems, focussing on the effects of soil tillage and tillage implements on the soil. The chapter also explores how soil disturbance can by minimised during farming activities such as land preparation, seeding, planting, pest, disease and weed management, and harvesting.The third chapter provides a useful overview of the core principles of CA before moving onto examining the concepts of no-tillage agriculture, cover crops and crop residue management. The chapter also discusses the environmental benefits and ecosystem services linked to CA as well as economic benefits.The final chapter considers the use of NT and the importance of a fully-integrated cropping and residue management system to maintain soil health and productivity. The chapter also reviews how NT can be used to reduce erosion risk, as well as its role in optimising soil functions.
