NEW Dryland Salinity Now Fact Sheet Series

NEW DRYLAND SALINITY NOW - FACT SHEET SERIES

Through the Responding to Dryland Salinity Project funded by the National Landcare Program, Coorong Tatiara Local Action Plan has reviewed historical salinity information and merged it with new salinity, soil mapping & remote monitoring systems data.

This fact sheet provides land managers managing dryland salinity relevant information relevant to current land uses and management practices.

AGRONOMIC OPTIONS

Several Annual Legumes (Clover and Medic species) have low to moderate levels of salinity tolerance and can be utilised in salt tolerant pasture mixes in different situations. Click below to access the Annual Legumes Fact Sheet.

Nitro Persian Clover on the midslopeAnnual Legume Tolerances to Salinity and Waterlogging

Messina (Melilotus siculis) is an annual legume that is adapted to winter waterlogging and has moderate salinity tolerance (ECe 8-
30). It is best utilised in grazing systems as part of a saltland pasture mix where the additional benefits of nitrogen fixation can be
utilised. Click below to access the Messina Fact Sheet.

Seedling Messina Puccinellia seed heads

Puccinellia (Puccinellia ciliata) is a perennial grass that is tolerant to both salinity and transient waterlogging (inundation <4 weeks). It is dormant in summer with maximum dry matter production in late winter and spring. It has shown its ability to be useful in remediation of scalds, and its palatability makes it well suited to grazing systems in the Upper SE providing the areas is managed appropriately.

Puccinellia Tall Wheat Grass - Northern Outlet Drain

Tall Wheat Grass (Thinopyrum ponticum) is a drought tolerant, summer active, tussock forming perennial that persists in soils that
are waterlogged in winter and dry out during summer. It is best suited for areas that are going to be grazed to ensure that it doesn’t become unmanageable and spread unintentionally. Click below to access the Tall Wheat Grass Fact Sheet.

MANAGEMENT RECOMMENDATIONS & REMOTE MONITORING SYSTEMS

Since 2016, the Coorong District Council area has seen a growing increase in areas affected by dryland salinity. In response to this, the Coorong Tatiara Local Action Plan (CTLAP) have been working with farmers and industry across the region to further understand the issues and develop solutions to assist farmers in managing areas of dryland salinity; both in the areas of remediation of scalds, identifying ‘at risk areas’ and prevention of new scalds forming. The following recommendations have been developed as part of this process. Further information is available on each of these recommendations as part of the Dryland Salinity NOW package.

FINAL Management Recommendations

Programs undertaken by the Coorong Tatiara Local Action Plan have provided opportunities to explore what is and isn’t working in the management of local dryland salinity management systems. As part of this work, several observations have been made by farmers around the conditions that appear to improve results when remediating soils. In particular, the ‘flushing effect’ required by natural rainfall events and the importance of groundcover in these systems.

The opportunity arose to utilise automated monitoring equipment to test these observations by using automated monitoring equipment to measure the depth of the water table, soil moisture levels, soil salinity levels and environmental conditions in real time at three monitoring sites across the Coorong and Tatiara District Council regions. This data is updated via automated telemetry every 15 minutes and both real time and historical data can be viewed utilising the internet. Initial findings from the information being generated suggest that there are two very different dryland salinity processes that are occurring across the region
