Table 3

Ratio of the number of samples in the categories low/high concentration (c/C) and low/high precipitation amount (p/P) to the number of all samples, calculated for both nitrate and ammonium. Values for weak and strong samples are shown separately. Values in brackets show the number of samples in each category.
