The changes of soil mineral nitrogen observed on farms between autumn and spring and modelled with a simple leaching equation
The content of nitrate or mineral nitrogen (Nmin = N-NO3 – + N-NH4 + ) in soil in autumn is recognized as the indicator of potential risk of N leaching during winter. In this contribution, the …

Effects of liming and nitrogen application on the trace element concentrations of pastures in low mountain range
In less intensively managed grassland, the micronutrient concentrations in herbage are apparently more likely to be in levels between barely sufficient and deficient than to be excessively high. …
