In article are submitted data on change of biochemical processes in the peat soils located in various gidrologoclimatic zones of Belarus. It is established that activity of the main enzymes decreased by 1,2 - 2,3 times at advance from the South to the north. It testifies to considerable delay of processes of transformation of OV of peat soils and longer period of their preservation. It is established that in the southern and central zones activity of enzymes is defined by the content of organic substance in a layer of 0 - 20 cm. Activity of a peroxidase in the central zone and all studied enzymes in a northern zone doesn't depend on a stage of transformation of peat soils. The activity indicator полифенолоксидазы can be used for an assessment of the contents easily hydrolyzed, mineral (ammoniyny and nitrate) nitrogen.

In article are submitted data on intensity of issue of CO2, size of microbic weight and its respiratory activity, intensity of peat soils of various stages of transformation. It is established that these indicators substantially depended on intensity of drainage of soils, extent of their transformation, a way of use, fertilizers applied to systems, etc. factors. Close connections between activity дегидрогеназы and intensity of issue of CO2, and as the size of microbic weight (R2 = 0,81 and 0,91 respectively) are besides defined. The last dependences can be used for an assessment of influence of a way of agricultural use on the speed of a mineralization of organic substance.

Results of studying of influence of processing methods on growth processes фитоценозов long-term herbs are stated. It is established that productivity of long-term cereals and bean and cereal herbages at the 4th-hay cutting use it was more, than at the 2nd hay cutting. Clover creeping, a lyadvenets horned in one-specific crops at 4 hay crops formed big productivity, than at the 2nd for 32 and 22%, respectively. At introduction nitric подкормок N20 and N40 before a hay crop this difference was insignificant. Bean type of riding type - a lucerne the sowing campaign was steadier against change of number of hay crops and productivity practically didn't change. Allelopatichesky activity of the soil rizosfer of bean and cereal and bean herbages in the first year of life practically didn't differ. Rizosfera of a lucerne of a sowing campaign possessed bigger allelopatichesky activity, than a clover creeping or a lyadvenets horned. When subsowing in дернину on the peat soil tsenotichesky activity hedgehogs of the national team was above, than at a herd grass meadow by 1,7 times. Profitability of subsowing hedgehogs of the national team in made 45,6% (on a factor cost), and herd grasses meadow - 40,3%.

The article presents results of research overall content and the qualitative composition of humus of Brest Polesye gleysoils. The character changing the composition of humus of gleysoils, depending on the type of land, the degree of moisture and particle size distribution is considered. Shown that the humus content of gleysoils in the south-west Belarus increases and qualitative composition of humus improves with increasing degree of hydromorphic soils.

On the basis of generalization literary yielded and results of own experiments the general approaches to designing meadow агрофитоценозов, adapted for northern part of the Republic are formulated. Information on influence of various factors on tsenotichesky activity of herbs is provided. Are revealed dependence of quantity of leaves on cleaning terms. On the basis of it it is offered to prefer at haying use to those herbs which in process to preparation of forages lose leaves less. It is established that the lucerne has advantage in comparison with a clover meadow as long culture capable to grow without a perezaluzheniye on the same site not less than 6-7 years.

Results of researches of efficiency of bean and cereals are given in article travosmesy with participation of a cock's head sandy and a kostreets bezosty various norms of seeding. It is established, at creation of highly productive herbages on the basis of a cock's head sandy and a kostreets bezosty the ratio of seeds of these cultures respectively 100,0% + 40% where productivity of absolute solid is 15,0 c/hectare higher, than in chistovidovy crops of a cock's head sandy is optimum.
