STUDY SOME OF SOIL PHYSICAL PROPERTES UNDER DIFFERENT COVER IN MOSUL FOREST

. This study was conducted in three different locations under three vegetation cover in Mosul forest included the soil under Sycamoro trees, Italian cypress trees and River red gum. Soil profiles have dug and some soil physical properties have been measured at two layers (0-30 and 30-90cm )in each site . An equation has been used to find the relationship between soil texture depth and location . The results showed that the soil was well developed under the sycamoro trees as the depth coefficient of texture in creased however the soil was less developed under Italian cypress trees, mean while the soil under the River red gum trees appeared immature soil .The porosity showed different values, however the soil texture kept constant without any changes depending on the depth and location.
