Table 3.
Parameter estimates and their 95 % confidence intervals for annual total nitrogen, nitrate, ammonium, total phosphorus, phosphate and total organic carbon concentrations. Parameter estimates b 1…b 10 are annual specific concentrations i.e., treatment-induced excess concentrations above the background level is divided by the proportion of the treated area from catchment area. Bold values are statistically significant (P < 0.05)
