Sažetak
Grapevine chlorosis often occur on alkaline soils and are commonly associated with microelement deficiency, notably that of iron and/or manganese. As most soils in the Plešivica wine-growing region are of marked alkaline reaction, chlorosis of the variety Sauvignon Blanc (planted on SO4 rootstock) is a usual occurrence immediately before flowering. Trials were therefore set up to investigate Mn foliar application in 4 vineyards with different levels of physiologically active lime in soil. Although differences in leaf Mn contents were recorded between locations (97.44-134.38 mg kg-1), they are not results of soil lime contents but of a series of other factors such as ion antagonism and agroecological factors. This is corroborated by almost identical Mn values in healthy and chlorotic vine plants (114.40-114.71 mg kg-1). Significant differences were determined, depending on Mn fertilization (73.60-155.51 mg kg-1) and sampling time (61.06-190.50 mg kg-1). Investigations are continuing.
