Come and see acid soil managed better
FARMERS, fishers and anyone interested in works to improve the Richmond floodplain are invited to a groundwater control field day on January 24.
Richmond River County Council, WetlandCare Australia and the Department of Primary Indust-ries will hold the field day in the Kookami Swamp near Coraki, to inspect works funded by the Northern Rivers Catchment Management Authority and completed last year to raise groundwater levels.
Kookami Swamp was drained in the 1950s and has since become a source of acid water and blackwater in waterways.
Raising groundwater levels reduces the oxidisation of acid sulphate soils while promoting the establishment of native wetland plants and pasture grasses.
For example, native water couch is less likely to die when flooded, thus reducing the risk of blackwater production and the resultant poor water quality and fish kills.
As an acknowledgment of the project's improvement to fishing, locally caught prawns will be supplied on the day for all those attending.
The day will also promote new projects for 2014 including wetland and riparian restoration works funded by the NRCMA, which is now known as Local Land Services.
