<abstract xmlns="http://www.w3.org/1999/xhtml">The aim of this study was to determine the influence of organic matter from different sources on the yield of winter wheat and macroelements content in it. The experiment was carried out in stoneware pots sank into the ground filled up with 56.4 kg of soil: Haplic Luvisols formed from loamy sand. The soil was slightly acidic. The soil was mixed up with liquid form of salts: Cd(NO3)2, Pb(CH3COO)2 and ZnSO4. To the soil a brown coal preparation, so called “Rekulter”, brown coal, peat and farmyard manure were applied in the amount of 180, 140, 390 and 630 g per pot, which is equivalent to 5 Mg of organic carbon per ha. Winter wheat Triticum aestivum ssp. vulgare (L.) for grain was cultivated. The manurial value of organic substance originated from different sources expressed as the plants' crop was the highest for Rekulter and the lowest for peat. The addition of organic substance to soil contaminated with heavy metals causes the higher content of potassium, magnesium and nitrogen in winter wheat's grain. The content of calcium and sodium in winter wheat grain's did not depend from addition of organic matter to soil. Organic matter added into contaminated soil increased the uptake of main macroelements by winter wheat straw. Organic matter fertilization broadened the K: (Ca + Mg) ratio in grain and straw.</abstract>
