The current study aims at evaluating the impact of compaction on some physical properties and productivity of soils in El-Fayoum governorate.
Twenty four farms, 14 in Tamia and 10 in Fayoum, differing in their soil characteristic and management practices were chosen for this study. The obtained data of the penetration resistance (PR) for the two areas under study were relatively high and ranging from 1.06 to 3.00 MPa, and thus indicate relative difficulty of root – elongation through such soils. The study also indicated highly significant negative relationships between PR and both of soil organic matter and soil porosity. It also indicated a highly significant negative relation between soil productivity and the values of PR (MPa), most probably due to the limited supply of water, oxygen and nutrients, with consequent limited root growth as a result of soil compaction.
