Abstract
Earthworm samples were collected from orchard that located in Al – Zafarania south of Baghdad. The physical properties of soil had studied, include soil temperature, pH and moisture. Soil temperature ranged between 30C◦ to 35C◦ as recorded during the period of study. Earthworms have clear effect on the value of pH and that show in 7th day from the beginning of experiment, the value was 6.5 while moisture have ranged between 66.8 – 74.6% The microbial properties studied and included total bacterial count , total coliform count and fungi count, the studied show decline in the total number of these microbial organisms by earthworms in Bins that contained them. At last the chemical properties have studied and included organic matter, total Nitrogen, Potassium, Phosphorous and Calcium. The organic matter declined into 3.51 %, while increase in the percentages of N, K and P ( 0.089 , 97 and 47 ) % respectively , while the percentage of Ca little changed .
