METHOD OF EVALUATING ENVIRONMENTAL SAFETY OF UNCONVENTIONAL SEWAGE SLUDGE BASED FERTILISERS

摘要

FIELD: chemistry.SUBSTANCE: laboratory experiments employ soil modified with unconventional organic fertilisers in recommended doses. A soil sample which is not modified with unconventional organic fertilisers, having a similar grain-size distribution and agrochemical properties, is used as a reference.EFFECT: invention increases objectiveness of obtained results when evaluating possible toxicity of unconventional organic fertilisers.2 tbl, 3 ex
