Environmental state of chernozem regradated under various agricultural use
Keywords:
the environmental sustainability, structural-aggregate com¬position, humus, soil fertility, anti-erosion stability, chernozemsAbstract
The article provides an assessment of the environmental sustainability of chernozem regradated, which is degraded in terms of its fertility. It was established, that the dominant fraction in all soil layers is a fraction of large dust, the content of which varies from 40.7% in the rock to 51.6% in the transition horizons, and the content of physical clay is 34.1–37.8%, which gives grounds to classify the soil according to the Kachinsky classification to medium loamy. An environmental sustainability of chernozem on the capacity of the humus layer on all variants is estimated as high, and on the content of humus – as an average. The ecological stability is also high, and according to the physicochemical indices of chernozem regradated, except for the variant with intensive fertilizer system. The anti-erosion resistance of the air-dry aggregates for the organic fertilizer system was 73.9%, for the intensive system – 51.0% and is estimated as average, while under the virgin land – 88.2%. The bulk density was within the optimum range from 1.12 g/cm3 to the fraction to 1.25 g/cm3 for mineral fertilizer system. In general, for the most part, the environmental sustainability of the chernozem regradated is high and the soil is suitable for growing the majority crops.
