In the article there have been presented the results of research on the influence of soil fertilization by means of sewage sludge, waste and composts made from urban green, produced in Dano technology, within the crop growth of Miscanthus Giganteus and Virginia Mallow. Furthermore, there have been also studied the basic soil properties, soil, nitrogen, phosphorus, potassium, heavy metals. and the content of organic carbon. Among a lot of well-known energy plants there have been chosen Miscanthus Giganteus and Virginia Mallow because of their good adaptation to the Polish soil and weather conditions. These plants are perennial and within the appropriate fertilization they have the ability of the high crop whereas their fuel value is similar to the wood one. In the purpose of research conducted in May 2007 there have been established the vase experiment which was continued within three years. The soil, on which Miscanthus Giganteus and Virginia Mallow were planted, was taken from the area in the neighbourhood with Huta Częstochowa. The vase experiment was conducted from April 2007 to November 2009 outside the direct reach of the foundry. The activity of deposits and composts was compared with the impact of mineral fertilization. The complex analysis of interactions of these tested substrates enabled the following conclusion that the most beneficial for the physical and chemical properties of soil was to insert the deposits into the soil in the dose of 20 and 40 t/ha. The most intensive growth of Miscanthus Giganteus has been noted by the means of fertilization with sewage sludge in the dose of 40t/ha. The general average crops within three years for this specific fertilization are amounted to be at approximately 340 g from the vase and they were twice higher in comparison to the control combination. The relatively high growth of crops was obtained for fertilization of sewage sludge in the dose of 20t/ha (about 290 g from the vase) whereas for the mineral fertilization of the objects it was approximately 260 g. The high crops in the objects fertilized by the means of sewage sludge are closely connected with their high affluence within nutrients and their effective influence on physical, chemical and biological soil properties. What is more, the most intensive growth of Virginia Mallow has been admitted with sewage sludge in the dose of 40t/ha and 20t/ha. The growth of crops was similar within two of sewage sludge doses. The general average crops from three years time for these mentioned earlier fertilization combinations were about 240 g from the vase, twice higher in comparison to the control combination. The definitely lower amount of crops was obtained for the mineral fertilization (approximately 150 g from the vase) and by the means of composts. The results of experiment have shown that the growth of crops of these two plants is dependent on the year. In the first year crops were lower in comparison to the second or the third one.
