Abstract
No-tillage and other conservation tillage systems are very effective in reducing erosion, in part because macropores consisting of cracks, root channels, and worm and insect burrows can speed
the flow of water through the root zone. Macropores may also lead to faster movement of nitrates and pesticides through surface
horizons under no-tillage, with the potential to contaminate shallow
groundwater in Georgia. Our objectives were to compare macroporosity in conventional and no-tillage soils from Georgia, and to determine the effect of the initial rainfall on chemical leaching in these soils.
