Copper Losses in Surface Runoff from Flatwoods Citrus Production Areas


Crop production in areas with a high water table and poorly drained soils requires special drainage infrastructure to allow adequate rooting depth. In addition to facilitating drainage, this infrastructure also facilitates discharge of agrichemicals dissolved in drainage and runoff water. Copper export from bedded citrus production areas was evaluated using simulated rainfall events following application of copper. Copper concentrations in runoff water from individual water furrows ranged from 13 to 223 μg/L during the staged events, while copper loadings ranged from 32 to 302 g/water furrow.
