The assessment of soil and land degradation in Volgograd region, the case of agricultural farm Donskoe

Abstract In order to increase the competitiveness of an agricultural holding through the efficient use of the production factors, the modernization of an agricultural farm was carried out by exending the existing greenhouse with at least 700m2 for the intensive cultivation of ornamental plants - Thuja Orientalis. The material is produced by initiating crops in pots, with seedlings grown in pots or transplanting them in pots right after the first year of the multiplication and growing them in containers, appropriate to their size, until reaching their full value. From a technical point of view, reaching the objective will also be possible through a localized irrigation system.

The study was conducted in Wai Sari sub-watershed, Western Seram Regency Maluku to develop an accurate land degradation assessment model for tropical small islands. The Stocking’s field land degradation measurement and RUSLE methods were applied to estimate soil loss by erosion and the results of both methods were statistically tested in order to obtain a correction factor. Field indicators and prediction data were measured on 95 slope units derived from the topographic map. The rates of soil loss were calculated according to both methods, and the results were used to classify the degree of land degradation. The results show that the degree of land degradation based on the field assessment ranges from none-slight (4.04 - 17.565 t/ha/yr) to very high (235.44 - 404.00 t/ha/yr), while the RUSLE method ranges from none-slight (0.04-4.59 t/ha/yr) to very high 203.90 - 518.13 t/ha/yr. However, the RUSLE method shows much higher in average soil loss (133.4 t/ha/yr) than the field assessment (33.9 t/ha/yr). The best regression equation of logD/RP = - 0.594 + 1.0 logK + 1.0 logLS + 1.0 logC or D = 0.2547xRxKxLSx CxP was found to be a more suitable land degradation assessment model for a small-scale catchment area in the tropical small islands.

First Time

Nodosilinea epilithica Perkerson et Casamatta is reported for the first time for Russia. The sample was isolated from a typical chestnut soil in the zone of dry steppes (Volgograd Region) and its identity was confirmed by morphological and molecular analyses. The specific feature of the studied strain is its ability to form nodules at normal (60–75 μmol photons ∙ m-2 ∙ sec-1) light. The number of nodules is supposed to be related to the age of a cyanobacterial culture.

The genus Hemiflagellochloris Watanabe et al. was found in Russia for the first time. The algal strain was isolated from a buried solonetz in the zone of dry steppes (the north-end of Ergeni Hills, Volgograd Region). The morphology and ecology of this isolate are described. Its phylogenetic position within Chlorophyceae is determined by molecular analysis of 18S rDNA gene.

Two Age Groups

According to the authors, the prevalence of SOPR diseases is from 3 to 20%.In a study of 1573 residents of southern China in two age groups who use tobacco and alcohol, the incidence of SOPR was higher among men living in rural areas compared to urban residents. Among women aged 35-44 years, the incidence was higher in urban women, and in the 65-77-year-old group in rural women. In the course of studies in Brazil, among 335 patients older than 60 years, 646 diseases of the SOPR were identified. Similar results were obtained in the analysis of SOPR diseases in the Volgograd region of the Russian Federation
