WebIn all, some 300 soil profiles were examined. The report (available for download below) contains descriptions of the soil types (based on Northcote Factual Key classification) that occur across the Farm, as well as maps showing soil subdivisions, chloride, electrical conductivity and provisional land capability. WebRhoades et al. (1989). In this model, ECa was a function of soil water content, the electrical conductivity of the soil water, soil bulk density, and the electrical conductivity of the soil particles. Recently, techniques have been developed to use this model for predicting the
