The paper presents results of research on influence of fertilization with cattle liquid manure black currant of Broedtorp and Roodknop varieties upon contents of basic mineral elements: nitrogen, phosphorus, potassium, magnesium and microelements: boron, manganese in the lamine. Changes in chlorophyl content were also fixed. Seven kinds of fertilization with the manure and mineral fertilizers were used in the experiment. It was stated that because of fertilization with liquid manure leaves of black currant contained most nitrogen, phosphorus and boron. The greatest amount of magnesium was found in lamine from the object where bushes were fertilized with minerals, magnesium added. The greatest quantities of chlorophyll were found in leaves bushes fertilized with manure and with minerals with some magnesium
