CHLOROSIS RISK EVALUATION FROM A NEW VITICULTURE AREA LOCATED ON A FORMER ARMY REGION

摘要

In this work are presented original studies regarding soil characterization from a former army area, located in Nazarcea, Constantza, in order to setting out new viticulture area and to evaluate the chlorosis risk. Sodium chloride, total iron, potassium, calcium carbonate, phosphates and humus have been analyzed in soil samples by titrimetric and spectrometric methods. Physical characteristics such as pH and granulometry have been also determined. The mean of chlorotic power index (CPI), calculated for all analyzed samples show high values: 11.76 (0-20 cm depth), 73.48 (20-50 cm depth) and 108.66 (50-110 cm depth) that means high risk of chlorosis.
