Abstract: 
Analysis of leaf and soil samples from green and chlorotic vineyards did not result in a clear correlation between chlorosis and 1 of the soil factors determined (pH, concentration of HCO3-, water soluble P, DTPA[diethylenetriamine pentaacetic acid]-extractable Fe, Mn, Zn, Cu). In severe chlorotic leaves the concentration of all elements investigated was increased, while in weak chlorotic leaves the concentration of Fe, Mn, Zn, Cu and P remained unchanged. There was no change in the P:Fe nor in the K:Ca ratio of the leaves due to chlorosis, but significant differences existed in the ratio extractable Fe:total Fe and total P:extractable Fe between green and chlorotic leaves. The increased amount of Mn and Zn in severe chlorotic leaves reached 100%, the amount of Fe increased, which together with the high P-concentration, can be assumed as the main cause of chlorosis.
