Losses of nitrogen in surface runoff from a plantation horticulture farm in coastal Queensland, Australia

Level 1 General description

Purpose:

To determine the extent of surface losses of nitrogen from horticulture farms in coastal Queensland.

Methods (brief)

The nitrogen losses and its speciation in runoff from the farm were measured and compared with nitrogen in water and sediments of an adjoining catchment waterway.

Key findings (brief)

The weighted average concentrations of total sediment nitrogen (TSN) and total dissolved nitrogen (TDN) generated in farm runoff were 2.81 ± 0.77% N and 1.11 ± 0.27 mg N/L, respectively. These concentrations were considerably greater than ambient levels in an adjoining catchment waterway.

Concentrations of TSN and TDN in the waterway were 0.11 ± 0.02% N and 0.50 ± 0.09 mg N/L, respectively.

Location

Burnett Catchment in South-East Queensland ~24.866oS, 152.349oE
