@ In terms of the leaching extent, they are divided into typical soils, boiling up on the surface with the area of 15699 ha, and leached, boiling up in soil overbed, with the area of 7519 ha. The humus is of a humic nature, the structure is grain- lumpy, the texture is loose. The mechanical composition is clayey, containing 60.9-82.2 % of physical clay. Its water-physical properties are favorable. The humus layer is characterized by loose texture and high porosity. The characteristic (calcareous) types of humus carbonate soils contain in the upper 3.6-19.8 % of CaCos, the amount of which increases towards soil-forming rock (up to 65.8%). This is not the case with leached types. In view of this, the reaction of the typical soils is low- and medium-alkaline, whereas that of leached types is neutral and in rock - alkaline. The sum of absorbed alkalis is characterized by high indices - 44.9-47.5 mg-eq in the arable layer. The share of absorbed calcium accounts for 61 to 95 % of the sum of absorbed alkalis. Nitrogen oxides, which fall on soil surface with precipitation, are not absorbed by the absorbing complex, since the soils of this region have a negative charge and absorb only cations. Anions, including nitrates, are found in soil solution and can be readily washed out together with surface and intrasoil layer. Mountain and piedmont relief in the southern and central part of the region with large slopes, which turns into an inclined plain in its northern part, dense network of rivers and creeks, water containing gullies, high water erosion are conducive to intense surface rainfall runoff. Depositional nitrogen is washed off together with this runoff, flowing through a network of rivulets and gullies into the Laba and Kuban rivers and finally into the sea. The amount of surface runoff increases during the period of heavy rains in May, June and July, when their intensity surpasses the filtration coefficient of soil. The filtration coefficient for soils in the valley of the Laba river is 0.1 m per day, making it possible to identify them as semipermeable (0.001-1 m per day according to Savarensky, impermeable 0.001 m per day). The annual soil wetting on leached chernozems was found to vary from 0.6 to 3 m per day, depending on the amount of rainfall and specific features of topography. The hydrological regime is of a periodically washing type. Moisture is accumulated from October to March. The soil is wet within a 2-meter layer up to the least moisture capacity (LMC). PAGE 4-57
Precipitation during this period will permeate down to the groundwater table, since the moisture entering the soil, saturated to the least moisture capacity, is not retained by the soil and under the action of gravitational forces moves downwards into groundwater. 4.3.1.1 1.1 The Character of Land Use - Grain Crops, etc. Owing to the natural features in the Labinsk and Mostovskoy regions, agriculture is one of the leading production sectors. These regions are noted for the greatest agricultural development in the Krasnodar territory. Plowed fields account for the largest share in the structure of agricultural lands (73% in the Labinsk and 58% Mostovskoy regions). Pastures and natural hay fields account for about 30 % of the agricultural lands. The productivity of dairy cattle and fowl is very low. On the average the regional indices of annual milk yield is 20 % below the indices of the entire Krasnodar territory. The egg yield is more than twice below the territorial index. The clip of wool corresponds to the average territorial level. The main sectors of plant cultivation include the production of grain (about 70% of gross crops and 50% in the structure of the cultivated land and feeds (13 % and 37 %, respectively). Winter crops constitute the main part of grain crops. Plant cultivation also includes commercial sunflower and potatoes, grown for production purposes and seeds. Agricultural production in the districts is hampered by the development of erosion processes. Over the past 5 years the average crop yield in the farms within a 10-kilometer zone is as follows (in centners per ha): PAGE 4-58 /"
