After the trials made on the nitrates accumulation with the tomatoes, lettuce, cabbage and potatoes as influenced of different fertiliser doses has resulted that with all fertilised variants there were recorded higher NO 3 content than with unfertilised ones. The fertilisation with N 300 P 100 K 100 has conducted to a higher nitrate content both with the lettuce crop (1.548 mg NO 3 /kg) and cabbage leaves (1.008 mg NO 3 /kg).
