Dlouhodobý vliv ukládání půdy do klidu na kvalitu lyzimetrických vod

Original language description

The field experiment was established in Prague (chernozem, altitude 281 m. a. s. l., average annual precipitation 472 mm, average year temperature 9.3 °C) in 1996. The swards of grasses, legumes, legume-grass mixtures and spontaneous fallow were 3 timesor once per year cut, twice or once per year mulched). After 7 years the swards were treated by a total herbicide and Lolium multiflorum, as a model subsequent crop, was sown in spring 2004. Quality of lysimetric water (NO3-N concentration) was evaluatedin the first vegetation period of L. multiflorum. The highest NO3 concentration was found after legumes or wild fallow (140 and 160 mg.l-1 NO3). The lowest average NO3 concentration (105 mg.l-1) was recorded after grass forecrops. Comparing the influence of the forecrop treatment, the highest average concentration of NO3 was found on the previously mulched plots (136 mg.l-1), on the cut ones, where the mass was removed, it reached on average 108 mg.l-1 (one cut per year) and 116 mg.l-1
