Metals in Calamagrostis Epigejos and Solidago Sp. from reclaimed post-industrial wastelands

Phytocoenosis with main participation of Calamagrostis Epigejos and Sol-idago Sp. were created on the biological reclaimed post-industrial wastelands formed from coal wastes dump or Zn-Pb ores postflotation settlings. This plants are potential energetic biomass.The paper presents results of analysies of Fe, Pb, Zn, Hg, Na, K, Ca con-centration in plants taken from coal wastes dump and Zn-Pb ores postflotation settlings. This elements have basic influence on mineral matter behaviour during bi-omass co-burning in fluidized beds. ...

Possibilities of developing degraded and unculitivated lands in land consolidaton

The purpose of the paper is to present terminology and definitions of degraded and uncultivated lands as well as pointing of the possibilities of their alternative development. It's worth stressing that the suggested land development changes should result from the predestination of a given area to fulfill certain goals as well as be in accordance with rules of law. In the research part of the paper on the basis of two consolidated objects the analyzed areas have been identified and it has been determined how the as-sumptions about the project refer to the selected areas in the light of the proposed changes of their former use. ...
