The irrigation requirements for the period May‐August were investigated in relation to some physical properties of Cecil soil as affected by eight cropping systems. These systems ranged from corn grown continuously with stalks removed to sod continuously. The cropping systems had no effect on particle size distribution and total porosity, but crust strength decreased and aggregate stability and infiltration rates increased as the quantity of plant material returned to the soil was increased. The increased water intake was offset by increased deep drainage from the root zone, so there was no change in subsequent irrigation requirements
