Abstract

Abstract A micronutrient composition intended for application to the foliage, branches or barks of plants is described as containing oil soluble calcium, copper, molybdenum, magnesium, zinc. manganese or iron naphthenates of higher molecular weight in a horticultural spray oil. The naphthenic acids composition is made by mixing a solution of naphthenic acids in a light aromatic solvent with an aqueous sodium hydroxide solution to form sodium naphthenate, then adding an additional amount of solvent; heating and reacting with an aqueous solution of a water soluble salt of one of the above mentioned metals; separating the organic layer from the aqueous layer; washing the organic layer with water and then adding to the organic layer the quantity of spray oil required to obtain a composition having the desired concentration and removing substantially all of the light aromatic solvent so that the spray oil remains non-phytotoxic.
