In field experiments the foliar fertilization effects on potatoes (var. Dagra and. Marta) have beaen studied. Foliar fertilization with 6% urea and Agrosol - K caused an increase of P, K, and Ca contents in potato tubers as comparised to solid form fertilization. Magnesium content did not depend neither on fertilization form nor variety. Foliar fertilization enhanced the K:(Ca+Mg) ratio in the tubers dry matter.
