Abstract: [cze] [eng]
Cílem práce bylo zjistit vliv vstupu dusíku do půdy na emise N.sub.2./sub.O z půd odlišně zatížených pastvou skotu. Nárůst emisí po vstupu N je větší na více zatížené ploše než na ploše méně zatížené. Podél gradientu vlivu skotu se zvyšují vstupy živin, akumulace živin v půdě, mikrobní aktivity a také vliv přídavku N na emise N.sub.2./sub.O. The objective of this study was to examine short term effect of nitrogen addition into soil on emissions of N.sub.2./sub.O in two soils of overwintering area differently affected by cattle (M and C soils). The nitrate-N amendment increased emissions of N.sub.2./sub.O from soils, and in all three experiments, this effect was more pronounced in soil at location M, characterized by higher intensity of cattle traffic, according to our hypothesis. Cumulative production of N.sub.2./sub.O was proportional to the amount of nitrogen added at both locations, but it was more affected by soil NO.sub.3./sub..sup.-./sup.-N content than by the amount of nitrate added.
