The study has been conducted to know the variation in organic mater and carbonate minerals content with different depth ( 0 -15,15- 30 and 30 – 45 ) for some reigns in Mesan ( Ali Al-kharbi , Kumet , Ali Al-Sharqi , Amara center , Majer Al-Kabeer , Kahlaa , Khalat Saleh and Azeer ) . The study locations were chosen to represent area to taken soil sample .
The result showed that the organic matter content increased in surface horizons and decreased with depth . The highest OM value appeared in kumet reign ( 17 gm kg-1 soil ) . Whereas the value of other location were 11.5 – 15.1 gm kg-1 soil .Also the data showed that carbonate minerals content was highest in Majer Al-Kabeer (570 gm kg-1 soil ) . Whereas the value of other location were 350 – 520 gm kg-1 soil.
