Technical procedure for determination of physical degradation degree of soils in forest areas. On the field area there are established degradation degrees in soils and that by measuring the existing forms of physical damages, their deepth and surfaces that these cover (furrows, ravines, depth of soil profile, deflational cavities, alluviums, dry leaves, creeped rocks, stream rock floods, rocky ground and slithers) and upon in such a way measured values, to classify them into degradation degrees: low degradation, moderate degradation, strong degradation and extreme degradation of soil of forest areas. |
