A BETTER understanding of the movement of soil •** moisture in the relatively coarse-textured mesa soils of the Lower Colorado River Basin is of considerable importance to practical soil management practices in the area. This is particularly true when one considers the rapid removal of soluble plant nutrients associated with the excessive percolation losses characteristic of these soils. Inasmuch as dissolved salts move with the soil water, it was believed that a study of soil moisture movement, especially where soils are furrow irrigated, might provide useful information regarding fertilizer placement for row crop culture. A technique was followed very similar to that employed by Kirkham (3) (4) and later by Harding and Wood (2) in which they used a water soluble dye to demonstrate the streamline flow of water into tile drains. It provided a visual method of studying changes in directional flow of water moving through a soil profile as seen through the glass front of a lysimeter.
