Earthworms are important soil animals and perform vital functions in the soil that make better conditions for ecosystem, especially agriculture. Earthworms are involved in decomposing organic matters and mineralizing nutrients, controlling populations of pathogens, improving and maintaining soil structure and mixing organic matters in the soil. In this study, we discussed the effects of earthworm population and litter quantity on soil properties. Earthworm from the family of Megascolicidae was used in this study which is a native family of earthworm in Japan and accounts for more than 95% of earthworm family there. Experimental containers were set in the laboratory where earthworm population and litter quantity were controlled to observe its effect on soil properties. The results showed that, there was tendency of increasing survival percentage of earthworm. The Pearson correlation coefficient analysis showed that with increase in earthworm population and litter amount, there was increasing tendency in soil aggregates and available nitrogen content. The results for available phosphorus content and soil microbes did not show any relation with earthworm number and litter quantity. [ABSTRACT FROM AUTHOR] |
