| Abstract |
Earthworms are known to influence soil properties and hence to regulate underlying ecosystem functions such as soil organic matter (SOM) decomposition and soil erosion and quantifying their influence on SOM cycling in tropical ecosystems. The casts produced enhance microbial activities in soil that promote nutrient cycling and helps in aggregate formation and stability in soil. The aims of this paper are therefore to study focuses on the dynamic of physical and chemical properties of earthworm casts in different species earthworm ranging from low to high casting activity of earthworm.
The oven-dried weight of casts has been quantified in laboratory. Soil parameters like pH, EC bulk density, porosity , organic matter and exchange capacity have been quantified. The pH values of casts most of the values were ranged from 6.36 to 8.18. Fresh casts were characterized by higher EC, Mg2+ ,Ca2+, K+, Na+ and organic matter was significantly (P <0.05). The values higher in earthworm casts of khitarae(Pheretima peguana). The moisture content were significantly higher in fresh casts were ranged from 6.89 % to 33.93 %. The Khikhu (Pheretima Sp.) had bulk density values higher ranged from 1.19 g cm3 and most of the old casts. Earthworm casts are usually found to have greater exchangeable K+, Ca2+, and Mg2+ than bulk soil. Porosity were significantly higher in fresh casts of khitarae(Pheretima peguana). 69.52 %. The lower production of casts in the present study may be attributed partly to the lower abundance of surface casting species of earthworms and reduction in casting rates has been related both to the degree of plant biomass removal and systems.
