Management of Soil Acidity in No-Till Production Systems through Surface Application of Lime

Received for publication March 16, 2006. Increasing acreage of no-till (NT) cropping systems with surface applications of N fertilizer brings forth the important issue of management of acidic soils in these systems. Our objectives were to determine the vertical movement of surface-applied lime, and to determine if frequency or type of lime applied affects the rate of movement; to evaluate the effect of surface application of lime on soil chemical properties; and to determine the correct application rate of lime for acidic NT soils. Three NT field sites were identified that had below-optimal soil pH (
