“…Since ammonia emissions can be substantial if the fertiliser is not buried below the surface then this omission could substantial alter the conclusions of the study. Furthermore NH X may be more easily transported than NO X and has higher deposition velocities [Poor et al, 2001] and so efficiency of transport to the Great Barrier Reef lagoon is likely to be higher.…”

The Great Barrier Reef World Heritage Area contains highly sensitive ecosystems that are threatened by the effects of anthropogenic activity including eutrophication. The nearby sugarcane plantations of tropical north Queensland are fertilised annually and there has been ongoing concern about the magnitude of the loss of applied nitrogen to the environment. Previous studies have considered the potential of rainwater run-off to deposit reactive nitrogen species into rivers and ultimately into the Great Barrier Reef Lagoon, but have neglected the possibility of transport via the atmosphere. This paper reports the results of a modelling study commissioned by Australia's National Heritage Trust aimed at assessing whether or not atmospheric deposition of reactive nitrogen from Queensland's sugarcane plantations posed a potential threat to the Great Barrier Reef Lagoon. Atmospheric dispersion modelling was undertaken using The Air Pollution Model, developed by Australia's Commonwealth Scientific and Industrial Research Organisation. Despite the predominance of onshore southeasterly winds, the dispersion model results indicate that 9% of the time during the sugarcane fertilization season (in the modeled years [2001][2002][2003][2004][2005][2006]) the meteorological conditions resulted in emissions from the coastal regions of north Queensland being transported out over the ocean around the Great Barrier Reef. The results suggest that there may be a greater efficiency for transport out over the reef during October than for November and December. For the 2 months that exhibited the greatest potential for transport of coastal pollution to the Great Barrier Reef, the modeled deposition of nitrogen oxides (NOX) into the Great Barrier Reef lagoon was less than 1% of the total emissions from the sugarcane plantations, but was not zero. Our model has a simple chemical scheme that does not cover the full chemistry of all reactive nitrogen compounds and so the results are only indicative of the potential levels of deposition. Nevertheless, our study shows that small amounts of NOX that originate from sugarcane fertilization may be transported and dry deposited into the Great Barrier Reef lagoon. Other pathways not included in the modeling scheme may provide a more efficient transport mechanism. Whilst modern practices for the application of fertilizer to sugarcane plantations have drastically reduced emissions, the potential efficiency of transport of pollutants via the atmosphere may be of concern for other more highly polluting agricultural industries.

“…Correlations for regressions of N against insect numbers were not nearly as strong as those of the P regressions. These results may be due to direct ammonia (NH 3 ) loss and or uptake by water as it equilibrates with the atmosphere (Larsen et al 2001;Poor et al 2001) or perhaps to denitrification, because experiments were not axenic.…”

“…Wet buckets may not be useful for measuring NH x or TN because insect contamination is difficult to remove and microbes may cycle nitrogen in collectors containing water. Although some newer studies account for all factors in NH x deposition (Larsen et al 2001;Poor et al 2001), older works (Jassby et al 1994) that reported deposition of N to a wet surface should be viewed with caution. The NH 3 uptake or offgassing by a lake may be different than that occurring in the sampler because of differences in temperature and pH.…”

Measuring atmospheric nutrient deposition to inland waters: Evaluation of direct methods

Several methodological problems have been noted in analyses of atmospheric phosphorus (P) and nitrogen (N) deposition to inland waters. These include the quantification of contamination, rates of dry deposition of nutrients on wet and dry surfaces, and short‐range dust contamination. On and around a small lake in an agricultural region, we tested bulk and automated dry‐ and wet‐deposition samplers for the presence of insect and dust contamination and presented procedures to eliminate biases. Local (≤100 m) dust deposition appeared negligible, so land‐based measurements could be extrapolated to water; however, on‐ and near‐shore samplers collected more insect contaminants than off‐shore samplers. Insect contamination was large and most significant for estimates of P deposition, but a method to correct for it is proposed. We found that bulk and automated dryand wet‐deposition samplers yielded similar values when contamination was eliminated. Screens for atmospheric deposition samplers were tested and led to lowered insect contamination and similar deposition rates to samplers without them. Bulk sampling can provide acceptable estimates of atmospheric nutrient deposition if contamination is quantified or excluded. A wet surface does not differ significantly from a dry surface for measurement of dry‐fall of P. Short‐range transport of dust‐borne nutrients may be insignificant. Low‐cost bulk samplers yielded accurate measurements of atmospheric nutrient deposition.
