Variability of phosphorus load from agricultural land in Czech Republic Part I: baseflow condition

Popis výsledku v původním jazyce

Aim of the project is to describe unbiased P load from Czech agricultural land and evaluate its share on present stage of eutrophication. Load is described in terms of P quantity and bioavailability along with its flow, temporal, and spatial variability.Firstly, flow conditions divide the task into two disparate modi operandi. Secondly, spatial variability in P load during baseflow conditions is characterized in macro-scale. TP and SRP concentration in major soil groups were lower then mean of 0.069 and 0.038 mg.l-1, respectively. In addition, micro-scale variability is described by one example of eutric Cambisols, most extent soil group in Czech Republic. Thirdly, temporal variability in P load during baseflow conditions is characterized by seasonality of instantaneous load and interannual variability of specific yield. Annual specific yields of TP are estimated at range at 1-20 kg.km-2 of agricultural land. Only summer maxima at about 1/3 of profiles exceeded 0.035 mg.l-1 SRP.
