Nutrient Accumulation, Decomposition and sedimentation of aquatic macrophytes in southern Minnesota

Hill, Brian H
Five species of aquatic macrophytes from an agricultural drainage ditch and a second-order stream were analyzed for nitrogen, phosphorus and ash throughout the 1976 growing season. These macrophytes were observed to accumulate large amounts of these nutrients from the sediment and water. Determination of correlation coefficients showed that there was little or no significant correlation between nutrients in the water and in the plant tissue.
