Ilgalaikio tręšimo poveikis skirtingos kilmės dirvožemių biologiniam aktyvumui / The long-term fertilization effect on biological activity of different genesis soils

Grigaliūnienė, Kristina 17 January 2006 (has links)
The effect of organic and mineral fertilizers on biological activity of different genesis soils in long-term crop rotation trials was determined. Biological activity was diverse in the soils of different genesis and it activity correlated with some soil chemical properties. Organic and mineral fertilizers and their combinations more increased biological activity in the soil than only mineral fertilizers. Mineral fertilizers suppressed dehydrogenase and alkaline phosphatase activity (180 kg ha-1) with phosphorus and potassium fertilizers. The relationship between the crops grown, their yield and enzyme activity and respiration intensity in the soil was investigated.
