    The paper considers the influence on chernozem soil properties after the autumn application of calcium chloride as an amendment at the rate of 2.4 t/ha. At the end of the first year of aftereffect the results of soil analyses have shown the influence on such indices as pH, alkalinity and content of chloride, exchangeable cations and carbonates. During the winter period with 200-300 mm of precipitation chlorides from said amendment are leached to the depth of 50 cm.

    In the conditions of the Republic of Belarus there were presented the efficiency of connected applications on drained soils Lakeland area of the main melioration activities to drain the excess water on the surface and arable soil layer, increasing runoff, creating additional reserves of available moisture in the subsurface layer, and others aimed at improving the productivity of reclaimed land.

    The aim of the research is to investigate the impact of different doses of phosphogypsum as a chemical amendment on physical and physical-chemical properties of irrigated dark-chestnut soils in rice systems under constant flooding. The scheme of experiment: 1) moldboard tillage to the depth of 20-22 cm (control); 2) moldboard tillage to the depth of 20-22 cm + 10 t/ha of phosphogypsum (10 t/ha +PG); 3) moldboard tillage to the depth of 20-22 cm + 40 t/ha of phosphogypsum (40 t/ha PG); 4) imitation of soil milling to the depth of 20-40 cm + 10 t/ha of phosphogypsum (ISM + 10 t/ha PG).

    In the conditions of the Republic of Belarus it was determined that as a result of drainage and prolonged agricultural use (about 50 years) on the ground of former peat bogs there were formed peat-mineral soil complexes of different evolution stages with distinct rates of nitrogen fraction quantitative and qualitative composition. There were presented data of a structure of nitrogen breakup and its storage in 0-40 peat soils layer of different evolution stages.

    Woodless areas after clear cutting and fires are subjected to periodic water logging resulting thereby in water logging. The reconstruction of low-value forest stands (LVFSR) should become an effective measure for forest management on such areas. The experimental industrial station was the object of the study. It was founded by the Vologda laboratory of the Northern Forestry Research Institute. The LVFSR was carried out by means of planting and care of it. The total area of the low-value forest stands development of the open and shrubs overgrown territories was 42 hectares.

    The main tasks of the reclaimed and soil science have been formulated. It was noted that the radical and final reorientiring of the reclaimed and soil science as a whole in the country is necessary to working out the science methodology of support and effective functioning of the acting reclaimed complexes and systems. It is necessary to expand researches on microbiology, biochemistry and biophysics of agricultural lands with the purpose of the long-term strategy of the fertility, productivity and land immunity improvement.

    The objective of researches was approbation of concept of the recreational biogeosystem engineering by example of phosphogypsum recycling in soil upon simultaneously rotary ameliorative tillage in the soil layer from 30 to 60 cm. The research methods were stationary, field, laboratory, computed and thermodynamic which allows evaluating the extent of sustainability of the new phosphogypsum recycling biogeosystem in chernozem. The applying of proposed concept resulted in the improvement of morphologic soil structure, the increasing of depth and uniformity of sunflower root distribution.

    Soil change at management of its dispersed system by means of three-tier and rotor-milling tillage is studied. After single soil-meliorative rotor-milling plowing the processed soil layer consists of small units homogeneous for the size. There are no morphological signs of a solonetz pedogenesis restoration. The moisture of an atmospheric precipitation freely penetrates into the soil and easily distributes in artificial dispersed system. Readily soluble salts leach off to depth, sufficient for reducing of their influence on soil genesis.

    Necessity of the increment of the milk and meat production along with other agricultural products has caused the need to engage in an intensive agricultural use of new land, including flood areas that have been drained through the construction of polder systems. A total number of protective systems, fencing drained land from the influx of surface water compose over 3,900 miles of dikes. Nowadays reclaimed lands compose more than 220 hectares, equipped with polder system with mechanical water lift.

    The integrated method of dark-chestnut soil reclamation comprising green manure and application of different doses of phosphogipsum and mineral fertilizers (MF) calculated for planned yield was used in 2009. Influence of this actions on physical, chemical, agrochemical properties of soils upon rice growing, as well as on the yield of rice and winter wheat have been estimated during three following years. The variant "green manure +10 t/ha (double dose) of phosphogipsum + deep subsoiling + MF" had the best impact on soil processes.
