The relation between application and penetration of water into sandy soils

Abstract

The relation between application and penetration of water was examined on two soil types where the top soil is a coarse uniform sand. The relation y = -0.40 + 9 . 0 2x was found for Barmera Sand, and y = 1.48 + 9 . 1 8x and y = 1.86 + 10.31x for Winkie Sand where y = penetration of water (inches) and x = application of water (inches). The regression coefficients were significantly different from zero (P<0.001), and from this it is concluded that uneven distribution of water from sprinklers is mirrored in an uneven penetration of water.
