I came across a great resource if you are interested in learning about grain marketing or want to sharpen your grain marketing skills. The Farmer's Grain Marketing Primer developed by Carl German (University of Delaware Extension Crop Marketing Specialist) in collaboration with the Delaware Department of Agriculture and USDA RMA is an online tool that is comparable to an introductory grain marketing course. The information is both useful and easily understandable. It covers a wide range of topics including: basis, options, futures markets, crop insurance, profitability, market planning and many more useful topics. There is a wealth of information and resources on the site that is worth checking out.
