The Impact

The article highlights the results of research on assessing the ecological state of the land near the silt fields №1 and №3 of Bortnytska aeration station in the Zolochiv village community of Boryspil district in Kyiv region. The presence of previously recorded increased content of heavy metals in soils compared to the background content, both in terms of their gross content and the content of mobile forms was confirmed within the certain areas near the silt fields. For the elements-pollutants (Zn, Cu, Cr, Pb) at some points within the agricultural land, exceeding the values ​​of their gross content and the content of mobile forms (Zn, Cu) of the maximum permissible concentrations was recorded at 1.1-6.2 and 1.1 -2.6 times, respectively. The average values ​​of heavy metals content for floodplains (settlement) and agricultural land near silt fields indicate their prevailing values ​​for the latter in almost all elements, as well as exceeding the background values ​​and maximum permissible concentrations for the land where silt deposits were previously applied as fertilizers. Within the surveyed areas, soils are classified as unsalted, but the increased content of exchangeable magnesium may adversely affect soil fertility. Increased mineralization and content of ammonium and nitrates in groundwater are observed near silt fields, which is obviously related to the impact of silt water and can lead to deterioration of groundwater quality in the area of ​​their transit and discharge, in particular within the village Gnidyn. The area of ​​land with an extremely dangerous pollution rate in terms of total heavy metal is about 300 hectares, with a dangerous pollution rate is 260 hectares, and the estimated damage from crop failure may be 1.65 million UAH/year and 0.3 million UAH/year respectively. Within the areas adjacent to the silt fields, the condition of soils, water resources, cultivated products and the health of the population should be constantly monitored, especially when using the polluted land for agricultural use or housing.

The accumulation of heavy metals, primarily from the soil, takes place in the water and fodder plants. Sources are pesticides, polluted air and precipitation. Hazardous chemical elements in certain quantities enter plants from soil. It should be added that ballast substances from mineral fertilizers containing heavy metals are also found in the soil. It has been established that on the flat-foothill massif of the North Caucasus, the constant component of solid precipitation are such elements as chromium, nickel, lead, manganese and silver. Cadmium was not detected in most precipitation samples (less than 1.0 µg / l), but its concentrations exceeded the maximum permissible concentrations by 4–8 times, although its sources were not identified. Therefore, an agrochemical survey of agricultural land has been carried out and it has been established that the content of mobile forms of copper and zinc in the soils of the foothill areas does not exceed the maximum permissible concentrations. Meadow grass stands do not accumulate zinc, copper, lead and cadmium in quantities exceeding the maximum allowable levels. In general, in the foothill areas of the Krasnodar Territory, hay contains 11.0–25.0 mg/kg of zinc, 1.8–9.0 mg/kg of copper, 0.2–2.0 mg/kg of lead, and 0.06– 0.24 mg/kg cadmium. Studies have shown that the agricultural soils of the foothill areas do not contain exceeding MPC values of mobile forms of zinc and copper. But there are local foci containing lead in small quantities. In hay from arable land and natural forage lands, the amount of heavy metals does not exceed MDU.

The use of sewage sludge in agriculture decreases the pressure on landfills. In Romania, massive investments have been made in wastewater treatment stations, which have resulted in the accumulation of important quantities of sewage sludge. The presence of these sewage sludges coincides with large areas of degraded agricultural land. The aim of the present article is to identify the best technological combinations meant to solve these problems simultaneously. Adapting the quality and parameters of the sludge to the specificity of the land solves the possible compatibility problems, thus reducing the impact on the environment. The physico-chemical characteristics of the fermented sludge were monitored and optimal solutions for their treatment were suggested so as to allow that the sludge could be used in agriculture according to the characteristics of the soils. The content of heavy metals in the sewage sludge was closely monitored because the use of sewage sludge as a fertilizer does not allow for any increases in the concentrations of these in soils. The article identifies those agricultural areas which are suitable for the use of sludge, as well as ways of correcting some parameters (e.g., pH), which allow the improvement of soil quality and obtained higher agricultural production.

The Impact

The paper presents the results of a long-term study on the content and distribution of heavy metals in Haplic Chernozem of agrocenoses in southern zone of Rostov Region. The impact of various agricultural technologies traditional (using moldboard ploughing) and resource-saving (minimum and No-till) on accumulation and mobility of Pb, Zn, Cu in Haplic Chernozem in winter wheat cultivation is considered. The total content of Pb, Zn, Cu in the winter wheat areas corresponds to the background level and does not exceed permissible concentrations. Low mobility of elements (Pb 2.0-3.0%; Zn and Cu up to 1.0% as a percentage of their total forms) is a regional soil feature. In addition, the low availability of Zn and Cu in soils is due to their removal with the crops in the absence of micronutrient fertilizer replenishment. The significant role of soil organic matter in the accumulation of both total and mobile forms of heavy metals in soil has been confirmed. The intensity of the cultivation methods used has a significant effect on the total content of Zn, Cu and on the mobility of Pb, Zn, Cu in Haplic Chernozem.

Abstract The aim of the study is a comprehensive assessment of the state of natural-territorial complexes of the Baikal State Natural Biosphere Reserve, including an ecological and geochemical assessment of soils, analysis of plant communities, determination of the ecological and biogeochemical features of the vegetation of the area. The distribution of mobile forms of heavy metals in the soils of the Baikal Biosphere Reserve has been studied. The coefficient of total soil pollution has been calculated. The maximum allowable concentrations exceedances for Cr, Mn, Cu and Pb were registered. Analysis of the microelement composition of the crust of Pinus sibirica showed the accumulation of Cd and Ni in relation to the Dobrovolsky clarke in all the studied areas of the reserve. Based on the studies carried out, it can be recommended to monitor the ecological state of natural territorial complexes on a regular basis on the territory of the Baikal State Biosphere Reserve.

Humus Soil

Based on the screening of some heavy metals (HMs) content in the humus soil horizon of the Transcarpathian region, the regularities of the distribution of HMs in the soils of different landscape zones have been established. It is shown that  increasing of the terrain height, the content of HMs in soils decreases (except for Mn and Hg) and for the total HMs content  the values of the Spearman correlation coefficient are: Cu – (-0.84); Zn – (-0.83); Mn 0.77; Mo – (-0.91); Co – (-0.82); Pb – (-0.83); Hg – absent; for the content of acid-soluble forms: Cu – absent; Zn – (-0.72); Mn 0.75; Mo – (-0.89); Co – (-0.86); Pb – (-0.77); Hg is absent. This pattern is associated with the tectonic and geological features of the different landscape zones. The calculation of the migration coefficient (the ratio of the content of acid-soluble forms to the gross content) has been shown that in mountainous regions this indicator has the highest value for Zn, Pb, and Cu. That means the potential danger of migration of these heavy me­tals and their bioavailability. This is probably connected to the type of soil in the mountai­nous areas of the region. A pronounced inter-element correlation of the HMs content in soils (except for Hg) has been established and the corresponding values of Pearson’s coefficients for the gross content are: Cu:Zn – 0,96; Cu:Mn – (-0,84); Cu:Mo – 0,89; Cu:Co – 0,99; Cu:Pb – 0,87; Zn:Mn – (-0,79); Zn:Mo – 0,91; Zn:Co – 0,96; Zn:Pb – 0,86; Mn:Mo – (-0,86); Mn:Co – (-0,84); Mn:Pb – (-0,75); Mo:Co – 0,87; Mo:Pb – 0,81; Co:Pb – 0,87. This makes it possible to predict the content of several HMs in the soils of the Transcarpathian region based on the results of determining one of them. In general, the content of HMs in the humus soil horizon (total content and content of mobile forms) is lower than the corresponding values of maximum permissible concentrations.

The Impact

Agricultural lands occupy a special place in the structure of urban lands. There are horticultural and gardening associations on these lands. The “belts” of horticultural associations surround large cities and small settlements; dachas and vegetable gardens play the role of individual subsidiary farms and recreation areas. In Russia, the area of such lands is about 1.5 million hectares; in the Orenburg region - 18.7 thousand hectares. Studies show that horticultural ecosystems differ significantly from the adjacent urban and agricultural ecosystems in terms of the characteristics of soil and plant cover. The reason for this is private investment in the development of these territories, which needs to be managed. For the consistent development of these socio-ecological systems (SES), it is necessary to implement a soft management system. The purpose of creating and supporting of socio-ecological systems in the agricultural use zone and suburbs is the formation of a sustainable complex of natural and social conditions for gardening and recreation of residents; optimization of the belt of lands separating the city from agricultural land to reduce the impact of adverse environmental factors on urban ecosystems (wind restriction, fire safety, pests, etc.); use of these lands as carbon polygons for capturing and retaining of carbon dioxide.

In almost all industrially developed regions of the Russian Federation, the soil is contaminated with heavy metals (HM) often in concentrations which exceed limits of safety. This contamination causes degradation of agricultural land, which underlines the importance of the complex continuous monitoring of the dynamics of on-going changes in urban ecosystems against the background of natural processes. Quantitative assessment of the environmental sustainability of the soil according to the biological indicators of its condition is of enormous importance, in particular the balance of microbial carbon in soils, which are under varying degrees of anthropogenic pressure. Experiments were carried out to determine the phytoremediation potential of the spring rapeseed plants on soil contaminated with heavy metals. The aim of the study was to assess the respiratory activity of albic luvisol at different levels of its contamination with zinc and nickel under the conditions of a growing experiment with spring rapeseed plants. The experimental data on the respiratory activity of soil artificially contaminated with zinc and nickel in the dose range of 400-800 and 30-60 mg kg-1 of soil respectively, showed that microbial activity had a strong positive correlation with the presence of spring rapeseed plants in the vessels and weak correlation on the presence of toxic elements in the soil. According to the respiratory activity of albic luvisol, it was found that in the first 13 days of vegetation, cultivation of spring rapeseed plants had a positive effect on the sustainability of soil microbiocenosis to complex pollution with zinc and nickel.

The dynamics of the content of mobile forms of heavy metals (Zn, Cu, Ni) in the soil cover of agricultural land located near the sources of negative anthropogenic impact are considered. These elements have a pronounced cumulative effect, which confirms their concentration during 2000–2017. In the agrocenosis conducted to identify soil microbiota and identified representatives of the genera Agrobacterium and Agrobacter. The revealed features of interaction in the system "soil-microorganisms-plant" allow us to consider one of the tools to increase the productivity of grain agricultural systems by regulating the composition of soil microbocenoses. It is necessary to maintain optimal plant intervals of zinc, copper and nickel concentrations as significant micronutrients.

This research strives to provide answers regarding adaptation patterns of farmers in confronting climate change in Indonesia. The method utilized for this research is a mixed method. Qualitative data was acquired through a series of focus group discussions and in-depth interviews with farmers and agricultural stakeholders in Gunung Kidul and Sleman, Indonesia. Additionally, the survey was carried out to 220 farmers in both research locations. The two research locations were chosen based on the difference in agricultural land. The findings of this research show that farmers understand climate change is occurring in their region and it influences their cultivation method. Farmers utilize their personal experiences as well as local practices in adapting to climate change. The impact most felt by farmers is crop failure and a decrease in quality and quantity of agricultural crops. The ensuing implication is that farmer’s income declines more and more. This research found that agricultural product cost increased by almost as much as 50%, whilst farmer’s income merely increased half of that, which is 25% since climate change has affected their farming. Responding to the matter, the strategy farmers employ is by changing the planting pattern, using soil cultivation technique, plant pest management technique, and watering/irrigation technique.
