Municipal solid waste (MSW) has become a matter of increasing global concern. Biological conversion is considered to be the most applicable disposal method, especially for the organic fraction of MSW. The aim of this study was to evaluate composting as a treatment method for the sustainable management and recycling of MSW and to test the ecotoxicity of the compost produced on the landfill surface. The ecotoxicity of the compost was investigated by means of a set of biological tests. The ecotoxicological impact of the compost was evaluated by plant growth tests with white mustard (Sinapis alba L.) and barley (Hordeum vulgare L.). Plants were grown under controlled conditions for 21 days, in earthen pots, treated with MSW compost (MSWC) to study the effect of MSWC on plant biomass production. Sprouts and the number of growing plants occurring in the earthen pots were counted. The values obtained from three simultaneously conducted experiments were averaged and presented. Plants growing in the earthen pots with the compost exhibited increasing plant biomass while no changes were observed in their appearance; retarded growth or necrotic changes were not recorded. The ecotoxicity tests performed show that the analyzed compost produced in the composting plant situated on the landfill surface achieved high percentages of the germinating capacity of white mustard (Sinapis alba L.) and barley (Hordeum vulgare L.) seeds and can be therefore used in the subsequent reclamation of the landfill concerned.

Tank-mixes of metribuzin or cyanazine with sethoxydim, fluazifop-p-butyl, haloxyfop-methyl or quizalofop-ethyl were evaluated at Scott, Saskatchewan and Lacombe, Alberta for control of wild oats (Avena fatua L.) and barley (Hordeum vulgare L.). Metribuzin reduced the control of wild oats and barley when mixed with the four graminicides. Mixtures of the graminicides with cyanazine were not antagonistic and there was no loss of weed control. The addition of fluazifop-p-butyl, haloxyfop-methyl, and quizalofop-ethyl to metribuzin caused reduced phytotoxicity on wild mustard in the growth room.Key words: Graminicides, antagonism, metribuzin, cyanazine

Az 1994 őszén az Eszterházy Károly Egyetem Tass-pusztai Tangazdaságában csernozjom barna erdőtalajon szabadföldi kisparcellás nehézfémterheléses tartamkísérlet indult 8 elem (Al, As, Cd, Cr, Cu, Hg, Pb, Zn) vízoldható sóival, 3 terhelési szinten (30, 90 és 270 kg elem/ha), 3 ismétlésben. Jelzönövényként 1998-ban borsó (Pisum sativum L.), 1999-ben silócirok (Sorghum bicolorL.), 2001-ben őszi árpa (Hordeum vulgare L.), 2002-ben fehérmustár (Sinapis alba L.), 2003- ban rostkender (Cannabis sativa L.) és 2005-ben lucerna (Medicago sativa L.) termesztésére került sor. A kísérlet során vizsgáltuk a talaj és a növények nehézfémtartalmát, amelynek ismeretében nyomon követhető a vizsgált elemek talajban való viselkedésének és talaj-növény rendszerben való mobilitásnak alakulása. Az arzén kifejezett depresszív hatása a kísérlet első két évében mutatkozott meg, a kísérlet további éveiben a vizsgált növények esetén mérséklődött, majd megszűnt. Az arzén a maximális terhelésnél sem dúsult a növényi szervekben, mindössze néhány növény vegetatív szerve mutatott némi akkumulációt. A kísérleti növények szemtermése védettnek bizonyult az arzénszennyezéssel szemben. A kísérleti eredmények alapján kijelenthető, hogy az arzén mozgása gátolt a talaj-növény rendszerben, mozgékonysága a kísérlet negyedik évétől jelentősen csökkent.

In the field, eight barley (Hordeum vulgare L.) cultivars tolerated postemergence applications of AC 222,293 [a mixture of methyl 6 and 2-(4-isopropyl-4-methyl-5-oxo-2-imidazolin-2-yl) m- and p-toluate] at 0.4 to 1.4 kg/ha. AC 222,293 at 0.4 kg ai/ha applied at the 1.5- to 2-leaf stage controlled wild oats (Avena fatua L. # AVEFA) 96%, whereas 0.7 kg/ha applied at the 3.5- to 4-leaf stage controlled wild oats only 93%. Sugarbeets (Beta vulgaris L.) but not alfalfa (Medicago sativa L.), corn (Zea mays L.), pinto beans (Phaseolus vulgaris L.), or sunflower (Helianthus annus L.), were injured when planted 6 to 8 months after fall applications of AC 222,293 at 0.4 to 1.1 kg/ha.
