| Abstract | ||
| The effect of lateral position in furrow on moisture distribution pattern was studied in clayey soil under planted corn crop. There are two different lateral positions used in the experiment; up-hill and down-hill under three soil water contents (SWC): 20%, 29% and 35%. In case of up-hill position, the maximum water volumes were found in third and fourth layers for all treatments in Y-direction, while the maximum were found in first and second layers in X-direction. Also, for the vertical Y-direction, the water moved further vertically by increasing soil water content. In case of down-hill position lateral, the maximum water volume was found in third and fourth layers for all treatments in Y-direction, also found in third and fourth layers in X-direction. A saturated zone below the drip line was obtained only for the highest water content of soil. The total applied water volume in the first four layers increased with decreasing the soil water content in the last two layers. Decreasing in the soil water content allows more water to distribute in the horizontal direction, while increasing in the soil water content allows more water to distribute in the vertical direction. | ||
