3.1 Inorganic nutrient and TSS concentrations
In the Smugawka catchment, the lowest concentrations and fluctuations of
N-NH4+ were observed in the grassland
(0.02–0.73 mg·dm-3). The highest
N-NO3- concentrations were found on
arable land, and the P-PO43- level was
comparable on agricultural land and forests. The highest TSS levels were
found on arable land (Table 1).
