How Do Your Soils Handle Rain? Understand the Impact of Rainfall on Various Tillage and Crops

MSU Extension field crops educator Paul Gross will demonstrate a rainfall simulator. Observing rainfall infiltrating into the soil provides important insights into the physical properties of soil that affect crop production. These properties include surface sealing, porosity, aggregate stability and the interaction between these properties, crop residue and the plant canopy. Rainfall simulation evaluates the effectiveness of various systems to maximize water infiltration into the soil. Systems that will be observed include conservation tillage, conventional systems, cover crops and no-till. Jim Marshall from the Natural Resources Conservation Service will also be on hand to demonstrate the impact of cropping systems on aggregate stability and soil’s ability to handle heavy rainfalls.
