Cím:	Risk of agricultural use of sewage sludge compost and anaerobic digestate / Gulyás Miklós, Tomocsik Attila, Orosz Viktória, Makádi Marianna, Füleky György
Dátum:	2012
Megjegyzések:	The required quality of compost depends on its final use. All the requirements must be focused on obtaininga product with an acceptable aspect and smell, which is hygienic and free from (or with only traces of)impurities and contaminants. The concept of compost quality especially relevant when the compost is used directly,as a substrate for seedling production or in pots; these applications need high-quality compost. The qualityof compost based on concentrations of heavy metals and organic pollutants and on the absence of pathogens.The aim of the experiment was to prove the absence of the risk using this material in cereal production. The resultsof the last years suggest that there was no toxic element accumulation in the grain yield of triticale plants.Monitoring of phatogen reduction shows the conventional treatment by mesophilic digestion gives alimited reduction in the content of phatogens. The potential toxic effect of anaerobic digestate was measured inbiotest with ryegrass (Lolium perenne) and garden cress (Lepidium sativum) plants. The rapid biotests provedtoxic reduction of plant growth and root development at high rate application of digestate in the first days ofgermination. The reason of the reduction of root could be explained with the high ammonium concentrationof digestate.
