dc.description.abstractStraipsnyje pateikiami duomenys apie biogeninių medžiagų pasiskirstymą nuotakaus ežero baseino hidrografiniame tinkle. Tyrimai atlikti Nevėžio aukštupio Lėno ežero baseine, kuriame ežero plotas sudaro 6,4%. Tirtas fosforo ir azoto junginių kiekio nuotėkyje iš žemės ūkio naudmenų bei miškingos vietovės kaita ir ežero poveikis minimų medžiagų išplovimui. Nustatyta, kad didžiausios fosforo ir azoto koncentracijos buvo drenažo nuotėkio, mažiausios – ežero ištakio vandenyje. Iš žemės ūkio naudmenų per drenažą išplaunama 0,12 kg/ha bendrojo fosforo ir 16,0 kg/ha bendrojo azoto. Intaku į ežerą šių medžiagų patenka atitinkamai 0,06 ir 5,0 kg/ha. Ežere sulaikoma 56% bendrojo fosforo, 84% nitratinio azoto ir 60 % bendrojo azoto, patenkančilt
dc.description.abstractThe paper presents the data about the distribution of nutrients in water in the hydrographic network of the basin of a flowing lake. The studies were carried out in the basin of the lake Lenas situated upstream the Nemunas. The area of the lake covers 6.4% of the basin. The investigations included the following aspects: the change of the amount of phosphorus and nitrogen compounds in the runoff from agricultural land use and woody vicinities, and the impact of the lake on the leaching of those compounds. As the study results showed, the highest phosphorus and nitrogen concentrations occurred in drainage runoff water, the lowest ones were observed in water of the effluent of the lake. The amounts of total phosphorus and nitrogen leached from agricultural land use through the drainage make up 0.12 kg/ha and 16.0 kg/ha respectively. The amounts of those compounds brought into the lake by influent make up 0.06 kg/ha and 5.0 kg/ha accordingly. The lake retains 56% of total phosphorus and 60% of total nitrogen, 84% from which falls for nitrate nitrogenen
