Journal Title: Вісник Одеського національного університету. Географічні та геологічні науки - Year 2015, Vol 20, Issue 2
Abstract
The purpose of this work is to study levels and substantiation trends manifestations physical degradation of rendzinas Podilski Tovtry for further development of nature protection and eco- permissible measures for their protection and balanced economic use. Object of researching – rendzinas of the Podilski Tovtry. Methodology. The studied features of physical degradation rendzinas of the Podilski Tovtry. For determination the levels of physical degradation was used indicators to equilibrium density of composition, between- and internal aggregate porosity, the content of agronomically valuable structure and its water resistance. Results. Established that due to the small capacity of the soil profile and loose original composition, rendzinas in the process of development undergo within the entire sealing profile Is noted decrease in overall porosity and porosity of aeration in the upper arable layer agrorendzinas to 50–55 %, and under the plow sole – to 40–45 %. Established that reducing the content of agronomically valuable aggregates in the size of arable and subarable horizons, accompanied by increased content clumps. Structuring coefficient of agrorendzinas decreases in 1,5–3,5 times in comparison with virgin options. The proved levels and trends of degradation their physical condition, as a result agricultural use.
