English Abstract
Groundwater of 10 dairy farms was sampled during two periods and analysed for nitrate. The sampling was done in the first meter of the saturated zone with temporary wells and up to 6 meter below the freatic level with permanent wells. The analyzed nitrate concentrations do not differ between the two sampling periods, however at the farms there is a great difference between the two periods.
