Abstract

The required quality of compost depends on its final use. All the requirements must be focused on obtaining a 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 quality of 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 results of 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 a limited reduction in the content of phatogens. The potential toxic effect of anaerobic digestate was measured in biotest with ryegrass (Lolium perenne) and garden cress (Lepidium sativum) plants. The rapid biotests proved toxic reduction of plant growth and root development at high rate application of digestate in the first days of germination. The reason of the reduction of root could be explained with the high ammonium concentration of digestate.
