ABSTRACT
Infiltration rates on cultivated soils were determined by sprinkling and by means of water impoundment in small cylinder infiltrometers. Sprinkling procedures with a type FA infiltrometer, irrigation equipment, or manually controlled sprinkling were used in a manner that provided rate measurements. The cylinder infiltrometers were "single-ring" type.
Good correlation was obtained between sprinkler and cylinder infiltration rates by replication on cultivated soils. Correlation improved when median rates rather than mean rates, as measured with the cylinders, were used to reduce the effect of exceptionable intake values.
