A cover crop is any crop not grown expressly for harvest, but to improve the way the farming system functions. Cover crops are planted for many reasons, from fixing N to improving infiltration and preventing erosion.
Research Scientist Tom O’Donoghue from the University of Sydney explains in more detail some of the potential benefits of incorporating cover crops into a cotton system, describes his current research, and emphasises the importance of measuring the impact of your cover crops to ensure that they are achieving what you need them to do.
