Agrophysics peculiarity of brown mountain-forest soils of Ferghana valley

Middle mountains of the Ferghana mountains soils morphological features and other physical properties that point to development of soil formation process towards brown mountain and forest soils of a belt of brown soils are quite widespread. Brown mountain and forest soils represent result of imposing of mountain process of soil formation. Not degraded soils studied by us are characterized by good Argo physical properties, have a large number of cloggy-granular structural elements and water strong units, have the smallest density, the raised moisture capacity, the best aeration that promote to substantial increase of natural and effective fertility.
