Gives an idea of the nitrate leaching risks in grazed and in cut and grazed grassland by answering simple questions. Key question is the stocking rate during the season.

Gives an idea of the nitrate leaching risks in grazed and in cut and grazed grassland by answering simple questions. Key question is the stocking rate in LSU (Large Stock Unit). If it is higher than 721 LSU*day/ha, the situation has to change. If it is lower, the farmer has to answer if the stocking in the late autumn is higher or lower than 195 LSU*day/ha. If it is higher, the answer is a warning. If it is lower than 42 LSU*day/ha a cut can be done, if not, you get a warning. If it is between 42 and 195 LSU*day/ha, fertilizing less than 105 kg mineral N/ha is fine but more is not.
