| Popis: | We have investigated the influence of soil`s cultivation on the physical proprieties (apparent density,structure,pore proprieties modifications space and differentiated porosity resistance penetration ,hydrological proprieties,water`s permeability) in the gardens. Soil`s cultivation in the gardens leads to the formation of compacted horizon on the soil depth of 10-20-30 cm in which density of constitution is essentially increasing as compared with soils used for field`s cultures ( tf> t0,05).The most compaction was determined by tracks of the machine`s wheels where the density of constitution reaches 1,59-1,70 g/cm³.Investigated soils possess a satisfactorily structure, structure coefficient 1. Maintenance of water resistance units >0,25mm,decreases in arable horizon and in compacted layer, especially in chernozem of the new terracy where these indexes decrease till 36%-18%. These soil’s layers have a satisfactorily structure in the line, unsatisfactorily and badly by tracks machine’s wheels. The comparative research of trenched soil used for orchards cultivation and of land in crop demonstrates the difference between physical proprieties of the superior stratum. Trenched soils used for orchards cultivation are characterized by the formation of a settled stratum,disturbed at 10-30 cm deep also illustrating a more obvious technogenesys of these soils,as well as the regularities of physical in orchards soils. |
