NY511 - Acquisition of Overseas Nutrient Discharge Technology for Evaluation by Australian Nurseries

This 1995 study of overseas nutrient discharge technology recommended sub-irrigation systems be more extensively evaluated for containerised nursery stock production in Australia. The report also recommends: •investigating whether recycled nursery runoff water needs to be chemically treated •looking at slow sand filtration as an alternative to chemicals for disinfestation of run-off water •independently reviewing the disease suppressive qualities of composted sawdust-pinebark substrates in light of contradictory overseas findings •researching the release characteristics of 6-14 month controlled-release fertiliser formulations
