Influence of the different nitrogen fertilization and the participation of carvay (Carum Carvi) on Ca and Mg contentin in the medow green growth. The experiment has been carried in RZD Lipki using the split blocks with the uniform composition of mixture and changing participation of carvay varied (Carum Carvi). The nitrogen fertilization varied(from 0,80,160,240, 360 kg/ha), phosphorus and potassium ones were constant, respectioely amounting to 120kg/ha and 150 kg/ha. There have been collected two swaths of meadow green growth in which there were discovered magnesium and calcium (after burning samples using wet methods) by absorption metod. It was stated that the calcium and magnesium content in the dry mass of meadow green growth from the first swath was lover than this from the second swath. Magnesium shortage took place when the nitrogen dose amounted to 320kg/ha and when the carvay (Carum Carvi) participation amounted to 5 and 10%. However calcium shortage took place when the Carum Carvi participation amounted to 10%, independently of the nitrogen dose.
