| Abstract | ||
| The aim of this study was to study the effect of the added numbers of earthworms on physical, chemical and microbial characteristics in the soil. Earthworm samples were collected from orchard that located in south of Baghdad and three treatments were obtained T1 control (without earthworms), T2 10 earthworms / Bin, T3 40 earthworms / Bin, to study the physical characteristics which included temperature and water holding capacity (WHC), chemical characteristics included pH, organic matter (OM), total nitrogen (TN), potassium (K), phosphorous (P) and calcium (Ca), microbial characteristics included total bacterial count (TBC), total coliform count (TCC) count and fungi count (FC). The results obtained revealed that earthworms added (T2 and T3) have significant (P<0.05) effect on the value of soil pH, WHC, OM, TN, K, TBC, TCC and FC that started in the 7th day of study, where as no significant effect on the value of soil temperature and Ca were noticed compared with control (T1) during this study. The added numbers of earthworms to the soil have significant (P<0.05) effect, that change was great for 40 earthworms compared with 10 earthworms. | ||
