Abstract:
Sodic soils, which are widespread in Australian wine growing regions, restrict plant performance through poor soil and water and soil and air relations. In the northern Goulburn Valley of Victoria, an experiment was conducted from 1995 to 1998 in a vineyard block established with Chardonnay on Ramsey rootstock in 1972. The experiment was to improve root growth and vine performance by minimising hardsetting and crusting of the surface soil and decrease its susceptibility to waterlogging by improving water flow into the sodic subsoil. The factorial combinations of gypsum or no
