Enrichment of soil organic carbon by native earthworms in a patch of tropical soil, Kerala, India: First report
Abstract The role of earthworms in soil carbon dynamics is a recent avenue of research which is less studied in India. Three plots of 1 m3 size were laid in Jeevaka live laboratory (JLL)- a biodiversity rich area within the University campus. A control plot (CP) of same dimension was maintained outs...

| Sumario: | Abstract The role of earthworms in soil carbon dynamics is a recent avenue of research which is less studied in India. Three plots of 1 m3 size were laid in Jeevaka live laboratory (JLL)- a biodiversity rich area within the University campus. A control plot (CP) of same dimension was maintained outside JLL. Out of three plots within JLL, one was operated with native earthworm Perionyx ceylanensisMichaelson (100 numbers), water and cattle dung as feed (Jeevaka test plot- JT) and fenced with nylon mesh. Remaining two plots were operated as controls within JLL (JC1 and JC2). JC1 (Jeevaka control 1) was provided with cattle dung and water, while JC2 and CP (outside JLL) were operated without any supplements. Throughout the experiment native earthworm species have maintained their dominancy in all plots except CP where no earthworms were observed. At the end of a year-long study, JC1 with maximum diversity of earthworms showed better soil organic carbon (SOC) and particulate organic carbon (POC)-which is relatively a stable form of SOC. Overall findings indicate better the diversity of earthworms better is the carbon storage in the soil. |
