Abstract Deep placement of fertilizer and deep tillage were evaluated as to their effect on crop yields and root development. Experiments conducted for several years on four soil types showed that greater root development in the subsoil and increases in yield may be expected from deep fertilizer placement and deep tillage on soils that possess traffic pans. This was particularly evident in years of below average rainfall, when the increased root development in the subsoil caused by deep placement of fertilizer or deep tillage enabled the crop to better withstand dry periods.
