Abstract

The ability of soil to transmit water affects the rate, frequency and method of irrigation–and can often limit cropping possibilities in non-irrigated areas. Knowledge can be obtained on water movement through soil by measuring changes occurring after different periods of time. The gamma ray apparatus measures soil moisture on the basis that $$ gamma rays will pass through a $$et soil than a dry soil.
