Application of modelling by the study of ground water contamination with nitrates under grasslands.

Original language description

At permanent grasslands in the foothill regions of the Šumava (545 m.s.l.) subassociation Trifolio-Festucetum alopecuretosum Neuhausl 1972) relations between the use of different doses of N (+PK) and contamination of ground waters with nitrates have beenstudied with application of deterministic and probabilistic models with the aim of elaborating theoretical basis and new methodological approaches for polycriterical optimalization of fertilization of grass stands. Mutual relation between the use of do ses N (+PK), build up of primary production and perlocations of NO3- into ground waters, expressed by that of unit and marginal values of both these processes showed a mirror-like inversion course with a remarkable co-incidence of reverse local extremes.Within the range of doses from 0 to 100 kg N.ha-1 (+PK) P helps, at the ratio of the applied doses P:N 1:1,5-2,5 to a considerable decrease in the concentration of NO3- in ground waters. Specification of suitable doses of N (+PK) to ecolog
