EMILIAN TUDOR, TRAIAN CIOROIANU, CARMEN SIRBU, MIHAIL DUMITRU, ADRIANA GRIGORE, LAVINIA PARVAN FERTILIZER FOR THE TREATMENT OF IRON CHLOROSIS PHYSICO-CHEMICAL AND AGRO-CHEMICAL PROPERTIES
Iron chlorosis represents a physiological phenomenon with negative impact on the quality and quantity of grape production in the vineyards. The bicarbonates are considered to be the main group of compounds which immobilize the iron in the soil in forms not assimilable by the plants. The grape production in conditions of iron deficiency can be improved significantly by applying foliar fertilizers. The best result in mitigating the effects of iron deficiency were obtained by the application of the fertilizers which, in addition to a complex mineral composition, also have a content of organic matter in the form of humic substances or protein hydrolysate.
