Results of three-year water quality monitoring programs carried out in two small, lowland agricultural watersheds of various fertilization level: the Up­per Little Vermilion River (ULVR) located in Central Illinois and the Zagoż- dżonka River located in Central Poland, were analysed. Nitrate and orthophosphate concentrations and loads are presented and discussed in relation to meteo­rological conditions and hydrological responses of the watersheds. The watershed with intensive agricultural practice (ULVR) generates the runoff with higher con­centrations of nutrients. Concentrations of the considered nutrients were, in the case of N-N03 about 7.1 times, and in the case of P-P04 about 1.6 times higher in the ULVR than concentrations in the Zagożdżonka River. Nitrate-nitrogen losses amount to a significant part (about 15%) of applied total nitrogen fertilization in the ULVR. High concentration of P-P04 in runoff from Zagożdżonka watershed has also been recorded.
