Indicator protocols: Total phosphorus + flow leaving a sub-catchment or whole catchment

Nutrients in aquatic environments: phosphorus.

Phosphorus is an essential element required by animals and plants and high levels of phosphorus can be an important contributor to eutrophication – especially in freshwater and estuarine systems. Symptoms of eutrophication may include algal blooms and seagrass decline. Phosphorus in aquatic systems is generally partitioned into particulate (organic and sediment-bound) and dissolved fractions. Dissolved phosphorus (measured as FRP) is found in the form of (more)...

Indicator protocols: Total nitrogen + flow leaving a sub-catchment or whole catchment

Nutrients in aquatic environments: nitrogen

Nitrogen is an essential element required by animals and plants. However, high levels of nitrogen can also be an important contributor to eutrophication - especially in estuarine and marine waterways. Symptoms of eutrophication may include algal blooms and seagrass decline.

Indicator guidelines: nutrient concentrations in the water column and/or sediments

Estuarine, coastal and marine habitat condition

This document presents the recommended monitoring guidelines for collecting, collating and reporting information on nutrient concentrations in the water column and/or sediments for national, state/territory and regional application.

Root Zone Water, Salinity and Nutrient Management Under Precision Irrigation

The SRD8 project has an ongoing commitment to the development of salinity risk management strategies and tools designed to limit the damaging effects of salinity in the root zone, a fact that is most clearly represented by the establishment of 20 trial sites distributed through a range of growing conditions in SA, NSW and VIC.

Tri-State Project - Impact of Salinity on Horticulture in the Lower Murray

The project, started in November 2003 and to finish in early 2007, is split into two stages and deliverables are spread over agreed milestones. Stage 1: Specific tasks and main deliverables for Stage 1 are: A detailed literature review of the salinity relationships for the commonly grown crops (grape, citrus, stone fruit, melon and vegetables) in the Lower Murray region; Identify the knowledge gap in salinity relationships; Explore the salinity (more)...
