Due to Worm's Activities Physico-Chemical Parameters of Soil Get Change

Abstract

Earthworms are well known oligochaetes for improving fertility status of the soil. Physico-chemical parameters (PCPs) of worm's habitati.e. soil, contribute a major role not only in determining worm's density and species richness in a particular ecosystem but also affects their living pattern. Although, few workers have reported that worm-castings plays a significant role in decreasing pH, bulk density (BD), and % moisture content (MC) and by increasing the level of % water holding capacity (WHC), %nitrogen (N) and % organic matter (OM) of the habitat; while others reported that PCPs of worm-castings depend on the habitat and soil characteristics. In the present studies, an experiment was carried out during rainy season,2013 under laboratory conditions to assess alterations in PCPs of soil due to worm's activities by seven species of earthworms of western Uttar Pradesh state of India. These studies conclude that alterations in PCPs of the habitat (soil) depend upon the worm's species as they were found important creatures for alterations in PCPs of the soil in the study.
