    The aim of the study carried out on the basis of a field experiment was to compare results obtained during cultivation of winter triticale in the organic and conventional farming systems. Comparing these two systems (organic with conventional), changes in the content of macroelements (phosphorus, potassium, calcium, magnesium), and microelements (manganese, iron, zinc and copper) were analyzed in the triticale grain. The study involved four triticale varieties: Benetto, Cultivo, Grenado, and Moderato. The field experiment was performed in 2010–2011 at The National Research Institute for Fisheries Affairs Mecklenburg – Vorpommern in Gulzow, Germany. Grain of all triticale varieties grown in an organic systems contained more phosphorus and magnesium. Compared tillage systems did not differentiate calcium and potassium in grain of triticale Benetto, Cultivo, Grenado, and Moderato varieties. No relationship was found between the total content of phosphorus, calcium and magnesium vs. cultivars. The total potassium content in triticale grain was differentiated by the varietal factor. The triticale grain of all tested varieties (Benetto, Cultivo, Grenado, and Moderato) grown in organic system was characterized by higher – by ten or so per cents – iron, zinc, manganese, and copper contents as compared to the conventional systems.

    The aim of the three-year research project was to assess the impact of digested sewage sludge, wheat straw and EM-1 preparation on changes of the cadmium content and pH in the media made on the basis of soil and ash. Effective microorganisms preparation (EM-1) and ceramic powder EM-X, provided by the Greenland Company, were used as activators of biochemical processes. Festulolium braunii (Felopa cultivar) was grown in a pots. The acidification of the media consist of soil or ash and sewage sludge, wheat straw and EM-1 microbiological preparation has been obtained after three years. No effect of added components on changes of the cadmium content in the media based on soil and fluidal ash from coal has been found. Cadmium content in the investigated fluidal ash from coal and sewage sludge was not a limiting factor for their use as fertilizer and for land reclamation purposes.

    Zawartość cynku i miedzi w trawie Festulolium braunii i podłożach wykonanych z popiołów z węgla wzbogaconych materią organiczną i aktywnymi mikroorganizamami

    The aim of this study was to assess the possibility of recultivation of coal fluidal ashes by combining them with fermented sewage sludge, straw, and active microorganisms (EM-1). In the three-year study with Festulolium braunii (v. Felopa) copper and zinc contend were investigated in beddings and grass. The following components were used in the experiment: light soils, fluidal ash from CHP Źerań, wheat straw, municipal sewage sludge. As factors activating biochemical processes the following substances were used: active microorganisms EM-1 and ceramic powder EM-X. The addition of sewage sludge in combination with wheat straw to beddings constructed on the basis of soil and ash increased zinc content, especially in the first year of the experiments. The addition of sewage sludge and straw to the beddings with the soil was the main factor responsible for increase copper content in the beddings. The amount of copper was not exceeded of the limit typical for the soil. Introduction EM-1 to the beddings has not impact on the zinc and copper content in the beddings. The results indicate the possibility to use of municipal sewage sludge as a fertilizer or/and for the recultivation purposes.
