This is a pilot study to rigorously determine if broad-scale pasture legume plantings, particularly of leucaena and butterfly pea, represent a risk to reef water quality by increasing loads of nitrogen in runoff waters compared to grass only pastures. Nitrogen loads from both grass only and grass/legume pastures will be contrasted against loads from virgin Brigalow scrub to investigate the change from the native, pre-European landscape to the current agricultural landscape.
