Change of soil properties and microbiological activity under the vegetation of pastures

Most of the territory of the Navoiy province of Nurata region is occupied by the degraded pastures
\nwhich are the main source of food supply of animal husbandry. This paper is devoted to investigation
\nof agrochemical and microbiological properties of soils of pastures under agrophytocenosis of 1986,
\n1996, 2012 and under natural pastures of the study area. It is revealed that improvement of biological,
\nagrochemical properties of the studied soils, depends on duration of the period of use of the land in the
\npasture regime. Features of biological parameters of the degraded soils depending on their prescription
\nof use and type of plants, humus content agrochemical properties are revealed. If the activity of
\npasture plants during 3–19–29 became a permanent factor pasturable plants (zhitnyak — Agropyron
\ndesertorum. L., chagan — Halothanus subaphyllus, astragal — Astragalus agameticus Lipsky) improve
\nsoil properties and increase microbiological activity of light gray agricultural soils. Refs 20. Figs 3.
