title: Impact of copper application on soil metabolism, energy budget and formation of stable aggregates by anecic earthworm in tea plantations.
abstract: The preparation of daily energy budget of earth worm Lampito mauritii showed (i) decrease in consumption by about 66%, (ii) decrease of egestion 97%, (iii) decrease in growth by 80%, and (iv) enhancement in maintenance cost by about 31.5% on exposure to 8 ppm copper in comparison to zero level exposure. The stable aggregate formations also decreased by 67.6% at 8 ppm copper as compared to zero level exposure. Two way ANOVA showed significant decrease in stable aggregate formation and biomass at 5% level of significance on exposure to 8 ppm copper. The soil metabolism also increased under the negative impact of copper.
