    The aim of the study conducted in the years 2008–2009 was assessment of the effect of growing media on rooting of apical and leaf-bud cuttings of hairy columnea (Columnea hirta). Medium components included sphagnum peat, perlite and zeolite in the following variants: 1. deacidified sphagnum peat, 2. zeolite, 3. peat with zeolite 3:1 v/v, 4. peat with zeolite 1:1 v/v, 5. peat with zeolite 1:3 v/v, 6. perlite, 7. peat with perlite 3:1 v/v, 8. peat with perlite 1:1 v/v, 9. peat with perlite 1:3 v/v. After 6 weeks of rooting, the number of developed roots and their length, the number of roots longer than 3 cm, and also the number of offshoots developed by cuttings. Apical cuttings developed larger and more complicated root system than leaf-bud cuttings. The plants that were rooted in media with the addition of zeolite or perlite (25–50%) produced many roots. The number of long roots were the biggest in the medium peat + zeolite 3:1 v/v.

    Zmiany zawartości żelaza i manganu w podkładach wykonanych z osadów ściekowych, słomy pszennej i popiołów fluidalnych z węgla kamiennego w połączeniu z efektywnymi mikroorganizmami (em-1) oraz w uprawianej na nich trawie Festulolium braunii odmiany Felopa

    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 formulation effective microorganisms (EM-1). Based on the results of the three-year study with Festulolium braunii, variety Felopa, the influence of factors introduced in the experiment on the iron and manganese content in the soil and grass. The following components were used in the experiment: light soils, fluidal ash - provided by the Vattenfall Heat Poland Company in Warsaw, from CHP śerań, wheat straw, sewage sludge was collected from commune sewage. As factors activating biochemical processes the following substances were used: formulation of effective microorganisms (EM-1) and ceramic powder EM-X, which were provided by the Greenland Company. Results obtained in the experiment allow formulating the following conclusions. Application of activating substances, in the form of effective microorganisms (EM-1) formulation and EM-X ceramic powder, had no significant effect on the change of the content of exchangeable iron and total manganese in bedding and manganese in grass. After three years of experience bedding containing ash is still characterized by a higher iron content compared to the overall abundance of soil, although these quantities have been reduced compared to the initial period. Weight ratio of Fe/Mn in the grass, Festulolium braunii Felopa variety show that over time, reducing the amount of manganese in the grass going down to a greater extent than iron.
