Effects Of Soil Nutrients Variability On The Activity Pattern of Eudrilus Eugeniae (African Nightcrawler) and Lumbricus Terrestris (Common Earthworm) in soils from Pulau Banding, Perak

This study aims to concentrate on the activity pattern and adaptability of both earthworm species, Eudrilus eugeniae (African Nightcrawler) and Lumbricus terrestris (Common Earthworm) under various states of soil nutrient in Pulau Banding soil samples from Perak. The parameters of the soil nutrients concerned like nitrogen, phosphorus, potassium, and organic matter percentage have been measured in order to determine their effect on the earthworm behavior. Under laboratory conditions, the movement, burrowing, and mixing in soil behavior of both species was observed at different levels of nutrients. The results showed that earthworm ecological processes in soil nutrient heterogeneity have major implications for both species' activity patterns, with Eudrilus eugeniae being more responsive and sensitive to variation in nutrients compared to Lumbricus terrestris. The results highlight the pivotal role of soil nutrient composition in regulating earthworm ecological processes that ensure better soil health and fertility. The study provides important insight into the biota-soil nutrient relationship, supporting more optimized management of Pulau Banding soil ecosystems and other tropical ecosystems.
