Manganese status in vine leaf on calcareous soils after Mn foliar fertilization
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.
