Annotation: it has been hypothesized that algae in bedassore fields soils overlooking agricultural arable fields in the southern sarkhads of the Fergana Valley occur at different depths, different temperatures and conditions with different moisture levels, according to which the number of species in the Cyanophyta section was the highest, followed by the Chlorophyta section algae and The Last by the Xanthophyta section algae.
Keywords: Fergana Valley, arable land, bedassore fields, Cyanophyta, Chlorophyta, Xanthophyta, Bacillariophyta
Most of the Fergana Valley area is adapted to the cultivation of agricultural crops, with crop rotation for crop rotation to obtain abundant dressing. In this case, acorns are planted in exchange for wheat crops, mainly legumes. From such crops, more alfalfa is grown. Legumes enrich the earth with nitrogen. Here is the species diversity of algae in the soils of such lands am will be unique.
Winter soil samples were taken on the 5cm surface of the soil at a depth of 50s, 10-12 cm at a depth of 60s, 5.50 s in a layer of 45-50cm, moisture content of 45%. A total of 51 species and algae belonging to species varieties were identified in the aquatic cults of the specimens obtained. They are as follows.

Of the soil samples taken during the winter season, 51 species and species of chilli algae were identified. Just above the solution line of the tube wall developed Gloeocapsa minuta, Dictiococcus mucosus, Chlorococcus humicola. Tube wall solution line Oscillatoria brevis, O. amoena, Phormydium fragile, PH. fonticola, Schizothrix coriaceae, Ploctonema became a curtain dressing consisting of notatum cells. They are accompanied by Chlorella vulgaris from Green chlorococci, Ch. mucosa, Ankistrodesmus falcatus f. ferrestris et al. In the veil on the surface of the solution, Anabaena variabilis f. ratundospora, A. variabilis f. tenuis, A. Sphaerica, A. Minutissima, Phomidium fragile, PH.
