Soil water extraction dynamics of dryland cotton in various row configurations

Abstract

The soil water extraction dynamics of dryland cotton grown in various row configurations on some major Queensland cotton soils are being quantified. The data will assist in the further development of a cotton simulation model "CERCOT". This model is to be used to determine the outcome of various management scenarios relating row configuration, planting time and plant available water supply. This paper presents some results obtained on one soil type during the 1997/98 season.
