The article deals with the results of gild studies of regimes of work of irrigational sumps, working without dam and at dam water intake from the river Amudarya. The regimes of peculiarities of sedimentation are identified and dynamics of siltation of sediments in sumps in conditions of changing water levels and channel processes in the water intake zone. Recommendations for improving the operation mode of the settling tanks in the lower reaches of the Amudarya river are propsed.

One of the measures to eliminate the consequences of the Chernobyl accident was the exclusion of highly contaminated land from agricultural use. Due to the positive dynamics of the radiation situation, the issue of land return becomes relevant. However, in the period of exclusion of these lands the land clearance degradation processes were developing. The second part of the article is devoted to the issue of economic evaluation of the expediency of land return and the mutual coordination of the results of separate stages of complex ecological and economic evaluation. The research was carried out in Mogilev branch Institute of radiology (Republic of Belarus).

The area of lands in Karelia that do not satisfy sanitary and hygienic standards is increasing. The major shift is observed in areas under influence of industrial enterprises which emissions influence the condition of soil cover and surrounding water bodies. The study shows results of research of natural waters and soils of agricultural lands that are under influence of a mining company in Karelia. The purpose of research is to study aerial technogenic influence on soils of reclaimed agricultural lands nearby a quarry of a mining company. Among purposes were research of element structure of snow fallout and soils. A shift in physical and chemical characteristics of soils was found during research of dust pollution of agrolandscape. As a result of research a concentration ratio of some chemical elements was estimated as well as total indicators and levels of pollution of natural waters and soils. Content of chemical elements (Fe, Mn, Ni, Co, Cu, Cr) can be described by high level of concentration ratio, and these elements are the main pollutants. Recomendations were suggested to organise sanitary protection dust-catching forest belts along the source of technogenic pollution as well as carrying out of intensive dust-catching activities.

The article considers three ways of watering potatoessprinkling, furrowing, drip and two methods of hilling – ridge and ridge at early spring and summer planting times. The use of drip irrigation systems in the cultivation of potatoes in the subzone of light-chestnut soils of the Lower Volga region leads to an increase in yield of 63 % compared with sprinkler irrigation, at 31 % compared to irrigation furrows in the spring planting time and by 34 % compared to sprinkler irrigation, by 28 % compared to irrigation furrows on the options for summer planting time. Ridge hilling technique led to an increase in potato yield compared to the ridge technique by 8.5…13.3 % at early spring planting times and by 6.6…13.5 % at summer planting times. The analysis of yield of the main production shows that potatoes of spring term of landing formed mass of tubers to 57,4 t/ha, and at summer plantings to 62,6 t/ha. On average, the yield of potatoes at summer planting dates was higher than the yield of potatoes at spring planting dates by 13 %.

The article discusses the results of long-term field research on irrigation of perennial grasses with livestock runoff. The aim of the research was the experimental justification of land reclamation measures and drainage-free run off during irrigation of land with runoff from pig-breeding complexes. Experimental studies were conducted on a specialized reclamation system in Orsha district of Vitebsk region, where the soil cover is represented by sod-podzolic loamy soils. The experimental design included 8 options. As a result of research, it was found out that irrigation with livestock runoff leads to compaction of the upper soil layers. In the arable layer of 0–20 cm, the additional density increased from 1.26 to 1, 32 g/cm3, or 4.8 %, compared to the control, and in variants with irrigation and drainage measures, the compaction was somewhat less. In the soil layer of 0–40 cm, deconsolidation was greater only in the variants with soil deepening and loosening by 4 %, and when applying straw – by 5.1 %.In the 0–60 cm layer, a decrease in the density of addition was observed only in the variants with deep loosening and the introduction of straw. It was also found out that soil water loss varies over time. It is most intense in the first 2–3 hours and almost completely stops after 10–18 hours for monoliths with a thickness of 0.4–0.6 m, and in monoliths of 1.0 m, after 36–48 hours. The highest intensity of water loss was registered in options 5, 6 and 7. The lowest was in the control variant and option 2, where no land reclamation measures were taken. In options 5, 6 and 7, a decrease in the intensity of water loss by years was noted. Thus, in option 5 in 2000, water loss amounted to 0.9 mm /h, in 2001 – 0.87 mm/h, and in 2002 – 0.85 mm/h. Similar patterns were revealed in options 6 and 7. In the control option and option 2 without agro-reclamation measures, the intensity of water loss also decreased. The decrease in the intensity of water loss over the years is associated with changes in the density of the soil caused by anthropogenic impact on it. First of all, with compaction by farm machines and ongoing irrigation of perennial grasses.

The smallest moisture capacity in medium-thick peat soil in a meter layer is 671,2 mm, which is 19,3 % more than that of low-power and 38,9 % peat-gley soil. During the formation of the first mowing of perennial grasses, the moisture reserves in the 0,5‑meter layer were always in the optimal range (0,7–0,9 HB). The lack of moisture during deep occurrence of groundwater (1,2–1,6 m) causes a decrease in the yield of the second mowing of perennial grasses by 46–89 % in peat-gley soil and 25–40 % in medium-power soil. The arable layer of peaty-gley soil contains 4,4 times more nitrates than the average power. Without fertilizing after 3 years, the amount of nitrate nitrogen in peaty-gley soil is reduced by 1,9 times, low- and medium-power soil – by 2,3–2,4 times. The amount of nitrate nitrogen is more than that of ammonia, in peat-gley soil 4 times, low-power – 3,5 times. Reserves of available phosphorus in the arable layer of peaty-gley soil are 2,5 times greater than in lowpower, and 3,1 times in average power. Without fertilizing after 4 years, in the arable layer of peaty-gley soil under perennial grasses, the content of available phosphorus decreased by 45,4 %, in low-power – by 20,5 %, in medium-power – by 15,8 %. The advantage in potassium reserves in the arable layer belongs to peaty-gley soil and is due to its high content in the underlying mineral peat. In peaty-gley soil, the decrease in potassium reserves down the profile is 1,6 times; in thin soil – 3,2 times; average power – 2,5 times. Hay productivity of perennial grasses on peaty-gleyic soil is respectively higher by 8.3 and 24,5 % than on low- and medium-power peaty soils. A crucial role in increasing the yield of herbs and gaining increases is played by the nutritional regime.

The specificities of leaching (outflow) of chemicals from soddy-podzolic loamy deeply gleyed soil by infiltration and its return from groundwater during their evaporation are considered in the paper. In the annual cycle calcium is the element which is mostly washed out with amount of 89…106 kg/ha. It was shown that potassium (15…14), manganese (13,6…9,3), zinc (13,6…7,7), calcium (7,5…5,2) and magnesium (7,1…4,7) in percentage of the outflow return in the soil with the capillary rise of groundwater. It is shown that the ratio of infiltration (I) and evaporation of groundwater (K) in soddy-podzolic soil is within the range of 0,3…0,6 for medium arid, 2,6…2,9 for average long-term and 2,6…2,9 for humid conditions of atmospheric moistening. Thus, the lowest values of ratios for medium arid, and the highest ones – for medium humid conditions, which reflects the real specificities of the infiltration and evaporation of groundwater in natural conditions.
