In the irrigated soils of Azerbaijan dry subtropics, the positive effect of the organic fertilizer system on increase in soil aggregates of 10-0.25 mm in size has been established. With the introduction of 40 t/ha of cattle manure, the content of agronomically valuable aggregates in the arable and subarable layers of soils increased on average of 13.0% compared with the control variant. When studying permeability of alluvial meadow-forest zones under apple orchards, irrigated meadow-brown soils under vegetable crops and alfalfa, and also irrigated gray-brown soils under pastures found that the average water absorption rate is, respectively, the above then honed soils -0.0282 m/hour; 0.0691 m/h; 0.0768 m/h and - 0.5664 m/h. For the sustainable and effective functioning of the soil ecosystem, both unnecessarily high and low water permeability undesirable.
