Abstract
In condition of combined field experiment was studied the influence of liming with Ca(OH)2 at rates of 1.0, 2.5 and 5.0 t/ha on the input of calcium and magnesium in the grapes of fertility vines from varieties Sauvignon Blanc, Chardonnay, Cabernet Sauvignon and Merlot planted on Chromic luvisol. Samples were collected in two consecutive years. In the first year of the study was not found statistically proven variation of the Ca content in the composition of the fresh grape mass. The available Ca amount in grapes in ameliorative lime rate of 5.0 t/ha was lower compared to that what was found for the lower ameliorative lime doses. About magnesium was found statistically proven exceed at the variants with liming, compared to the variants without liming. Overall white varieties during the first year assimilated more Ca amount compared to the red varieties. According to Mg this difference was insignificant. The differences between limed varieties and the control variant in the second year of the study according to the Ca content in the grape were statistically proven at level of probability 95%.
