Organic nitrogen cycle, ammonification and nitrification activity in long-term field experiment

Original language description

The effect of organic and minerál fertilisation was evaluated in a mini-plot field trial, established in 1958. The paper summarises results concerning nitrogen cycle, incidence of micro-organisms participating at the nitrogen cycle and ammonification andnitrification activities. High doses of organic manure increased the soil organic nitrogen content, similarly to the organic carbon content. Nitrogen accumulation in these plots has shown a similar dynamics as the organic carbon accumulation. The resultshave shown that nitrogen cannot be accumulated in soil for a longer time period except in the soil organic matter. All mineral nitrogen applied to the mineral fertilised plots was lost. Organic manuring increased the average number of proteolytic bacteria, while mineral fertilisation decreased their number to about a half of that in control. Average number of the free living N2-fixing bacteria was lower in tilled variants as compared to non tilled control and it decreased continuously o
