Almost all Iowa producers would welcome rain, but if there is an intense downpour, some degree of soil crusting can be expected. Soil crusting most often occurs when rain separates the soil into very small aggregates and individual particles that cement into hard layers at the soil surface when drying occurs rapidly. And with the heat and wind so far this spring, rapid drying is a possibility.
