The measures on preservation of swamped soils have an effect upon structure of a water balance and promote improvement of water saving in river basins. However, there are difficulties in a quantitative assessment of influence of bogs on creation of resources underground and day waters.National parks and system of legal protection of connatural remarkables play essential role in preservation of swamped lands. It is necessary more widely to use legal and economic tools in order to encourage creation and up-dating small swamped lands in an agro-landscape.Creation of a small amount of swamped terrains will not exert essential influence on a structure of water balance of the country. On the contrary, the plenty of small swamped lands can become as the essential factor of improvement of water quality and increase in water resources.

As a result investigations, it is established that on the soils polluted with heavy metals and situated in landscapes on watershed terrains, realization of measures promoting to blocking toxicants in soil and conversion of them to a hard-accessible form for plants is necessary.

The influence of the basic cultivation of derno-podzolic soils having a different degree erodibility on changes of moisture stores in a soil and water consumption of farm crops is investigated. It is established that the available moisture stores in non-eroded soil exceed those in strong-eroded soil by 2…31 mm depending on conditions of year. Tillage influences the contents of the available moisture in a soil profile in the spring season but during crop vegetation period their action is insignificant. Due to presence of crop residues in surface layer of soil, nonmoldboard cultivation promotes to additional accumulation of a moisture in the spring season in arable layer by 2…6 mm on the average.38In years of sufficient humidification, the basic source of moisture (80 % and more) for plants is precipitation, and role of soil moisture is minor. In hard-dry years, the fraction of available moisture can be equal to 86-89 %. Under a non-moldboard cultivation in comparison with a moldboard plowing, the overall moisture consumption is higher by 2…13 mm on non-eroded soil and 16…20 mm on strongeroded. To produce a unit of yield of cereal and grass crops, moisture is consumed on eroded soil more than on non-eroded soil, especially under a non-moldboard cultivation.

Using of the known qualitative laws of farming (equivalence and independence, minimum, joint operation of factors of vital activity of plants) the approximated quantitative model of farm crop yield is proposed. The model is based on the principles which can be characterized as the quantitative laws of farming: the law of gradients, upon that, estimation of influence of any factor on a yield can be realized by means of the function of the corresponding gradient which is a relative measure of deviation of a parameter (quantitative characteristic) of the given factor from nominal value (value, defining a top yield); and the law of the stochastic (random) nature of forming (creation) of yield . Comparison of the model with known empirical connections between a yield and the limiting factors of environment is presented.

The drainage reclamation directed to remove excess moisture gives rise to substantial change both regime characteristics and basic properties of soils with a different degree of humidification. Thus, in-depth transformation of soil-formation process and gradual creation of drained soils having their inherent diagnostic signs and properties take place. Eluvial-illuvial processes accompanied with increase in mobility of a humus and also removal of it and elements significant physically for plants from upper soil horizons strengthen in a soil profile. The better structural organization, presence of pores-fractures, increase of a filtration coefficient is characteristic for subsurface horizons of drained soils in comparison with un-drained ones.

Profit has increased from 20 to 118 $ per hectare or by 18-50 % per conventional unit of costs.

The assessment of a degree of biological degradation of drained peat soils in the Brest Polesie by level of total biomass soil microorganisms is given. The powerful peat soil was characterized by a maximum biomass of bacteria, actinomyces and fungi: (724,20 ± 48,40) ·10-5 g/g. Total biomass of microorganisms in the degrading-peat and peat-mineral soil having a medium degree of mineralization was less by 5,43 times (р < 0,05) in comparison with the biomass in the powerful peat soil. This has allowed to evaluate the first soil by biological criterion as degraded one having the degree of degradation of 1 (in the 0-4 scale). The remaining varieties of the investigated soils (humus-peaty, humus-gley, humus-peaty-gley and mean-power peaty) had degradation degree by biological criterion equal zero.
