Article explains a team of CSIRO scientists at Floreat Park believe perennial plants may hold the key to stabilising salinity in Western Australian farmlands. The salt problem could solve itself when the salt deposits are leached away in a few centuries, it is not feasible to wait that long. Scientists with the CSIRO's Land Resources Management Division have begun a biological programme they hope will show farmers that by turning a small part of their land over to perennial pastures, shrubs or trees they will be able to reduce the salinity problem on their farms and in the streams. CSIRO biologists are working with hydrologists on deep bores to snap freeze the cores in liquid nitrogen so they can be brought to Perth for analysis. Spokes...
