The results of three-year investigations on cv. Galaxy F1 of cabbage grown commercially in the south Poland, an important agricultural region, are presented. In 2005-2007, a field experiment was carried out on silty clay soil containing 0.91-1.02% organic carbon and of the soil acidity pH(H2O) 7.18-8.21. Effects of the N form (ammonium sulfate and UAN: a solution of ammonium nitrate + urea) and the method of application (placement and broadcast techniques and complementary foliar fertilization with urea and Supervit K) on the P, K, Mg, Ca and S concentrations in edible parts of cabbage were surveyed. Nitrogen fertilizer was applied at the rate of 120 kg N ha–1. In the placement treatment, fertilizer was applied on each plant while transplanting seedlings in rows 10 cm deep and spaced 10 cm from one another. Foliar nutrition with 2% urea was carried out 3 times and once 1% Supervit K was applied. The content of nutrients in cabbage leaves changed over the years. On average, the highest K and Mg content was in 2006 and the lowest P, K, Mg and Ca content appeared in 2007, with the harvest of 2005 being intermediate. The sulfur leaf content was the highest in 2007 and the lowest in 2006. The concentrations of P, K, and Mg in edible parts of cabbage were less than sufficient. The source of N affected P concentrations in cabbage leaves in 2005-2006. Slightly higher P amounts were detected in cabbage fed UAN than ammonium sulfate. None of the examined factors influenced K and Mg concentration in cabbage. In 2005-2006, slightly lower concentrations of Ca in cabbage fed UAN than ammonium sulfate were noticed. In every year, higher S concentrations in plants fed ammonium sulfate were detected. In 2005-2006, cabbage fertilized with the broadcast technique had slightly higher amount of S than the one given the placement treatment. Foliar fertilization did not affected the content of the examined nutrients in cabbage in any year of the trials.
