SUMMÀRY:
Danish firm «Harsoe» proposed a theory of acidification of the pork muck H2S04 to pH 5.5-6.0-6.5 with introduction of it as an organic fertilizer – 30, 40, 60-75, 70-80 t/ga. Integral indicator BOD20 in the aqueous extract acidified manure water compared with control increased from 7360 to 8320 mgO2/dm3 (III class of danger). In acidified muck mixed with environmental sorbent hlaukonito-lit (1:1) after three months of exposure BOD20 decreased from 8320 to 210 mgO2/dm3 (IV klas danger), and using the resulting organic fertilizers not objectionable. Economic efficiency by reducing the danger of class III to IV with using our modified formula (p.249.5 and p.246.2 Tax Code of Ukraine) is the application of organic fertilizers 30 t/ga – 119 griven; 80 t/ga – 397 griven.
