On-farm research is motivated by a desire to learn more about a product/practice/system on land you manage. You may now have the tools (yield monitor, weighing grain cart, etc.) to accomplish on-farm research that generates information you can use in management decision-making. Your on-farm research should start with the design of a ''valid comparison", according to your research objective (Soil Science News & Views 26:01).
