Fig. 4. Ponded water infiltration into traditional-till (TT) and no-till (NT) soil at three slope positions at three paired farm sites in September 2001. Measurements were obtained in standing and undisturbed wheat stubble. The quantity of water that had infiltrated into the soil was recorded at 10-min intervals during each 120-min run. Figures A, B, and C are the three slope positions for summit, side and toe for Site 1. Figures D, E, and F are the three slope positions for summit, side and toe for Site 2. Figures G, H, and I are the three slope positions for summit, side and toe for Site 3.
