Management of salinity may include establishing trees in saline areas to enhance discharge and may enable productive use of saline land. Field studies of the performance of trees in saline conditions are generally confined to the initial years after planting, and little quantitative data are available on the relationship between the growth rates of eucalypt species to soil salinity in field conditions at later ages (e.g. 10 years). In this study, the growth of irrigated Eucalyptus globulus, E. grandis and E. camaldulensis is examined in relation to soil salinity measured using an electromagnetic induction device (EM38).The EM38 was found to be an effective tool in determining survival and gr..View full abstract
Funding for this study was provided by the Victorian Department of Sustainability and Environment, the Victorian Department of Primary Industries, and the Cooperative Research Centre for Plant-Based Management of Dryland Salinity. The authors are grateful to D. Chessum who kindly allowed access to the plantation and maintained and applied water to the plantation. A number of people contributed to the design, establishment, maintenance and monitoring of the field study. The authors particularly thank J. Collopy, J. Morris, D. Stackpole and R. Stokes. They also thank K. Broadfoot and D. Cornwall from the Victorian Department of Primary Industries (Tatura) for instruction in the use of the EM38, and S. Yang for assistance with EM38 measurements.
