The objective of this study was to determine the area, severity and location of secondary saline discharge in the Volcanic Plains LMU's and present it in map and database form.
Aerial photos were used for the location of saline sites and an extensive ground truthing program carried out using the Inventory of Soil Conservation Needs techniques (ISCON) for the classification of salt severity.
A total of 8,349.6 hectares was found to be salt affected with sites varying in size from 1.1 m2to 264 hectares. The majority of sites were affected by a low level of salinity, although some were moderately or severely saline. The majority of sites had not been treated. This provides a significant opportunity to achieve both productivity and environmental benefits through the adoption of saline agronomy practices.
