There have been defined the manuring (with vermicompost I, II, and III and also mineral NPK fertilisers) influence on the content of macro- and micronutrientsnts in leeks. Two kinds of leeks were examined: Arkansas and Bartek. The experiment was carried out with four replications within randomised block designs. It turned out that the leeks fertilised NPK have had the biggest amount of nitrogen, potassium and sodium. The biggest content of calcium and magnesium was recognised in leeks from cattle manure vermicompost. Micronutrients content was less connected with fertilisation, but more with kind of soil on which leeks were growing.
