Changes in the N/S ratio and in the total S and N contents of the grain were investigated in one maize hybrid and one wheat variety grown in calcareous loamy chernozem soil at the Experimental Station of Debrecen Agricultural University. The crops were sown in mono-, di- (wheat, maize) and tricultures (pea, wheat, maize) within the framework of an NPK fertilization experiment and the above parameters were studied as a function of time. The experiment consisted of combinations of 5 fertilisation treatments, 3 irrigation treatments and 3 soil cultivation treatments in 4 replications, giving a total of 180 treatments combinations. The soil was slightly acidic (pH=6.4) with a moderately high humus content (2.5-3.0 percent), poor phosphorus and zinc supplies and good potassium, manganese and copper supplies. The CaCO3 content in the top 0-20 cm layer was 0 percent
