| Popis: |
A long-term wastewater irrigation on soil composed of glacial sand resulted in the transformation of the soil profile, which included chemical, microbiological, biochemical, and virological soil characteristics. The individual soil samples contained organic particles by weight, but these particles represented an important storage of nutrient and energy for microorganisms. The wastewater irrigation on a sandy soil resulted in positive effects on soil activities, and did not create any risk through pathogenic bacteria or viruses to a local deep groundwater aquifer. |
