Controlling Runoff from Subtropical Pastures Has Differential Effects on Nitrogen and Phosphorus Loads Patrick J. Bohlen* and Odi R. Villapando J. Environ. Qual. 40:989–998 Table 3 on page 995 should be replaced by the following table: Table 3. Average nutrient concentrations (±1 SE) in manual grab samples collected on five dates in 2005 and three dates in 2006 (N = 8) during flow events in pastures with unobstructed flow and pastures with reduced flow. There were no significant differences between pasture water management treatments for any variable (P > 0.05, Kruskal–Wallis test). Variable† NH4+ (mg L-1) NOx (mg L-1) TN (mg L-1) TP (mg L-1) SRP (mg L-1) SRP/TP
