“…This is because of natural proximity to the industrial city of Magnitogorsk (3.5 km) and anomaly of the region. Hence, the content of As in soils of the south of Western Siberia is 13 mg/kg [59], in the mining and ore region of the Urals it is 96 mg/kg, in the northern forest-steppe of the Cis-Ural region it is 20 mg/kg [41]. These authors believe that the permissible value for arsenic is underestimated; for example, the world's soils are considered uncontaminated when its content is 1-95 mg/kg [60].…”

Soil, geochemical, microbiological and archaeological studies were conducted at eight settlements dating from the Paleolithic to Late Medieval and New Times near the Southern Trans-Urals mountains, Russia. The forest-steppe landscapes, rivers and abundance of mineral resources have attracted people to region since ancient times. Properties of cultural layer (CLs): close to neutral pH, well structured, absence of salinity, enrichment with exchangeable calcium and anthropogenic phosphorus (0.2–0.4%). The majority of CLs start from 3–25 cm and last up to 40–60 cm and contain 6–10% organic carbon (Corg), in a layer of 0–20 cm because modern processes are developing here, at Ishkulovo site (around 14th century) Corg decreases to 1.3%, because CL is below 80 cm and in the absence of fresh organic material it is mineralized. The content of microbial biomass of the 0–10 cm layer is 520–680 μg С/g of soil, microbes cause the emission of 0.2–1.0 μg C–CO2/g soil per h. The proximity of the studied sites to deposits of copper, chromium, zinc, manganese and Magnitogorsk Metallurgical and Uchaly processing plants creates geochemical anomalies of soils. Pollutants are also released into the CLs from bronze products, ore, ceramic fragments and raw materials from their manufacture. It leads to the concentration of pollutants of the 1st (arsenic, lead, zinc) and 2nd (cobalt, copper, nickel, chromium) hazard classes in the studied CLs, often in quantities higher than the clarke and less often – more than the allowable content for human health.

“…Поведение качественных и количественных показателей плодородия почв позволяет судить о степени антропогенной нагрузки на тот или иной участок, что может быть использовано при разработке научно-обоснованного прогноза и выявления «чистых» территорий [2]. Основное предназначение агроэкологической оценки почвэто, прежде всего, всестороннее научное знание о почвах и почвенном покрове исследуемой территории, с целью рационального использования земельных ресурсов и правильной организации сельскохозяйственного использования ведения сельского хозяйства [3].…”

The article presents the results of agrochemical assessment of agricultural land for a 33-year period of use. The structure of the soil cover of the surveyed territory includes gray forest, chernozems, alluvial meadow, alluvial, peat-bog, their total area is 9034.5 hectares. The results of the survey revealed a decrease in the weighted average humus content in soils by 1.5%, the reaction of the soil solution is average acidic - decreased by 0.1 units, the content of mobile phosphorus decreased by 3.1 mg/kg, exchangeable potassium by 3.4 mg/kg. Based on the obtained data of agrochemical assessment of soils, an electronic soil map of the joint venture Yanybaevsky Belokataysky district of the Republic of Bashkortostan was created. Keywords: AGROCHEMICAL SURVEY OF SOILS, SOIL FERTILITY, MONITORING

“…Agroecological monitoring of soils includes quantitative and qualitative analysis of the territory, geoinformation (GIS) technologies with remote sensing of the Earth, study of the composition, regimes, and properties [DELLA CHIESA et al 2019;MILLER et al 2019]. Carrying out qualitative and quantitative indicators of soil fertility makes it possible to judge the degree of anthropogenic load on a particular site and can be used to develop a scientifically based forecast and identification of "clean" areas [ASYLBAEV et al 2018]. Agroecological studies are also crucial for studying the ecological functions of soils.…”

The article provides an assessment of soil fertility indicators of agricultural lands in the northern foreststeppe of the Republic of Bashkortostan within the Iglinsky region (Russian Federation). The content of humus, mobile phosphorus, exchangeable potassium, the thickness of the humus horizon, granulometric composition, morphological properties and soil washout were studied. It was revealed that the soil-forming process occurs on rocks of different ages and genesis, such as diluvial carbonate and carbonate-free clays and heavy loams, limestone eluvium, sandstone eluvium and alluvial deposits, which determine the diversity of the soil cover. In the study area, water erosion processes are developing, influenced by anthropogenic and natural factors such as planar and linear washout on slopes with a steepness of more than 2-3°and high ploughing of agricultural land. In terms of humus content, low-humus and medium-humus soils are widespread, accounting for 45.5 and 40%, respectively. The soil map was corrected and digitised to identify the main types and subtypes of soils, indicating the varieties at a scale of 1: 25,000. Digitised maps, taking into account the current state of soil fertility, are used to develop projects for inter-farm and intra-farm land management of organisations of the agro-industrial complex, state cadastral valuation of agricultural land, determination of land tax and development of measures to improve soil fertility.
