Instant Insights: Crop Rotations

This collection features five peer-reviewed literature reviews on crop rotations in agriculture. The first chapter discusses the effects of crop rotation and intercropping management practices and their impact on soil health enhancement and stability. It also considers the importance of leguminous crops and soil organic matter in maintaining healthy soils, sustaining crop productivity and enhancing biodiversity. The second chapter examines the principles of crop rotation, precrop effects in crop rotations, and the nutrient effects of legumes and other rotation crops. It also reviews the role of rotation crops in suppressing weeds, diseases and pests and studies rotations and crop yields, as well as the challenge of designing a crop rotation. The third chapter illustrates how crop models account for the interactions between soil, genotypes, management, and climate, on crops grown in various rotations, and their effects on yield and environmental outcomes under current and future climate scenarios. The fourth chapter assesses the potential of decision support systems for crop rotations in improving soil health and agricultural sustainability. The final chapter reviews how crop rotations with non-cereal species can be implemented to substantially reduce inoculum sources for residue-borne cereal leaf diseases.
