The present study aims to compare the quality of soil of different region of Haridwar with reference to physicochemical and heavy metal parameters. To fulfill the objectives of present study, soil sampling was performed in forest (control site), industrial, residential and agricultural areas in and around Haridwar. Soil samples were analyzed for different physicochemical and heavy metal parameters.  Values of all the studied soil parameters were found highest (an increase of 32% in temperature (16.63 to 21.640C), 121% in soil moisture (13.05 to 28.39%), 29.02% in soil porosity (37.56 to 49.03%), and 19.6% in the water holding capacity (36.22 to 43.58%), 74.18% in conductivity (0.25 to 0.40 µMhos/cm), and 203.78% in chloride (16.67 to 53.97mg/gm)) at the industrial area in comparison to other sites. During the course of the study, an increasing trend in all the parameters at all the sites was observed this may be due to the dumping of industrial solid waste and effluent. Although no negative impact was observed on the soil quality but continuous dumping will results in harmful impacts due to the accumulation of pollutants. Therefore there is a need for safe and proper disposal and utilization techniques to manage the enormous quantity of industrial waste. All the heavy metals (such as copper (0.050 to 0.055mg/gm), manganese (0.232 to 0.242mg/gm), nickel (0.035 to 0.036mg/gm), lead (0.039mg/gm), and iron (1.19 to 1.22) were found in higher concentration during the study period while cadmium was found absent during the study period.

The study presents three groups of Soil Quality Indicators (SQI) of arable lands in the Russian Federation, such as agroclimate conditions, soil parameters and negative soil characteristics. The selection of SQI meets the requirements of the crop growth model for calculating the standard crop yield. The application of SQI in the Grain Equivalent Model allows ranking quality of the soils of agricultural lands in the country. The share of the best quality Chernozems with the standard yield of grain crops exceeding 4 t/ha is about 10%. At the same time, arable Chernozems occupy nearly 66% of total area of agricultural lands. More than 74% of the arable lands including podzolized and leached Chernozems in the northern part and Chernozems southern in the southern part of the agricultural zone are characterized by medium quality with the standard yield of grain crops 2-4 t/ha. About 10% of the arable land occupied by Chestnut solonetzic and saline soils are of poorer quality with the standard yield of grain crops less than 1 t/ha. The proposed indicators are included in the government programs for valuating and monitoring the quality of agricultural lands. The universal validity of indicators is a basis for the development of a new generation of standards for the protection and rational use of soils based on modern digital technologies and GIS approaches.

As a result of increase in the number of residents of megacities, the anthropogenic impact on the public, recreational and agricultural areas is increasing. Anthropogenic load causes degradation of the natural structure of the city and has a negative impact on public health. In current situation, more recreational areas are organized for residents of the city. However, the organization of recreational areas does not always comply with the population requirements. In the formation that sort of spaces, it is necessary to obtain complete and reliable information about the quality of the environment, which can only be obtained through the regular monitoring studies. This article considers a number of recreational, agricultural and public areas under the noise exposure. The spatial organization of recreational areas should be carried out taking into account the main goal of creating a comfortable architectural and planning structure of the urban environment. This article shows the insolvency of the public, recreational and agricultural areas as comfortablespaces.

E-waste is a popular name given to those electronic products nearing the end of their useful life which has become a major source of heavy metal contamination in soil and hence, became the global concern. Various samples of soil were collected from different sites and were determined for heavy metal analysis by the ICP-AAS after the digestion process. The main source of contamination is illegal e-waste recycling activities such as burning of PCB's acid baths etc. Different soil indices like contamination factor, I-geo, pollution load index, were calculated to determine the quality of the soil. Results indicate that e-waste recycling and industrial area are strongly contaminated by the heavy metals. Physiological analysis of soil revealed that e-waste processing and industrial activities decrease the soil pH and organic matter while enhancing the electrical conductivity of soil. The exceedance of metal contamination imposed negative impact to the soil environment and human health.

The study of soil quality in irrigated areas is necessary to evaluate the sustainability of the agricultural production system. Indeed, the assessment of this quality is based on the physicochemical and biological characterization of soil parameters, as well as the knowledge of their spatial distribution and their evolution over time. This work aims to make a diagnosis of the current situation of soil quality of SidiYahya in the Gharb plain, Morocco. For this, sampling was carried out from 33 sites distributed over the studied plain during 2019. In this study, different soil properties including specifically texture, pH, electrical conductivity (EC), organic matter (OM), phosphorus (P2O5), and potassium (K2O) were measured while exchangeable sodium percentage (ESP) was calculated using the standard formula. Based on the observed soil properties a map was prepared by using a geographic information system (GIS), which was based specifically on the inverse distance weighted (IDW) spatial interpolation method. Data were processed using different statistical tools like descriptive statistics, correlation, and principal component analysis (PCA). Results of the study revealed that 70% of the soils have a heavy clayey texture with a predominance of vertisols (55%). Further, the study area soil is mainly alkaline (70%), poor in organic matter (61%) and phosphorus (52%), while very rich in potassium (70%), and non-saline (88%) contents. Soil pH was reported to be the least variable whereas sand, phosphorus, and salinity were the highest variable. IDW allowed mapping the soil properties by moving from punctual information to whole extent information. Furthermore, correlations were found between various soil properties by using PCA, 3 principal components (PCs) were able to extract 76% of the information from the 9 initial soil properties. Collected soil samples were grouped into 3 groups, based on their scores on the 3 PCs. Based on these two kinds of information, delineation of management zones can be established for a site-specific supply of agricultural inputs leading to better management of soil and water resources for securing their sustainable use.

Brick Kilns

The study was conducted to evaluate soil quality and impact of brick kiln on different physicochemical parameters of soils of agricultural field, located in the vicinity of Bhaktapur, Nepal. The study was carried out by determining the physicochemical characteristics of soil, soil fertility, and heavy metal contamination of soil. During the entire study period, water absorptivity of soil ranged from 2.4 to 3.3 mg/L, pH varies from 5.885 to 7.64, and organic carbon content and organic matter varied from 0.277 to 0.93%, from 0.477% to 1.603%, respectively. Nutrient content, that is, sulfate and nitrate concentration, in the soil ranged from 0.829 to 3.764 mol/L and from 0.984 to 29.99 mol/L, respectively. The findings revealed that concentrations of heavy metals (chromium and lead) were within permissible limit, although the levels were higher in soil at 50 m and decrease farther from brick kiln. However, the physical parameters and nutrient content were deficient in soil at 50 m while increasing gradually at distances of 100 m and 150 m. The variation of result obtained for physical parameters supports the fact that quality of soil in terms of heavy metal content and nutrient content was directly proportional to the distance from the kiln; that is, the quality of soil increased with increasing distance.

AbstractThe article considered the influence the various types of land use on microbial activity of soils and thus using this parameter as a universal test of soil quality. Samples for soil respiration studies were taken from agricultural areas, meadows, forests and urban areas (estate cottages). All samples were subjected to the same analytical procedure and the method of measurement was followed by a Substrate-Induced Respiration (SIR) method. Since all the samples were from neighbouring regions and were characterized by similar soil parameters, the obtained results allowed to assess the quality of the soil environment of the surveyed area and to evaluate the total rating of whole area. The obtained results allowed to observe slight divergences between soil samples taken from areas of different use. And although statistically, in this case, these differences were not significant, the characteristics of the respiration curves clearly indicate that there is a dependency between the form of use and the size and rate of soil respiration. In addition, the results have shown that single family housing does not exhibit as much anthropopression to the soil environment as it might seem.

The Impact

The paper proposes a new approach to environmental and economic assessments based on the author’s economic and mathematical model that takes into account the accumulation of hazardous pollutants in natural environments. It also presents the results of calculations showing the dynamics of the increase in the negative impact depending on the natural assimilation of pollutants. This data can be considered as a quantitative assessment of the “environmental cost” that society pays by consuming goods the production of which is accompanied by the accumulation of long-lived pollutants. It is shown that this “price” can very significantly exceed the eco-intensity calculated without taking into account the accumulation of pollutants. Thus, the accumulation of pollutants as a result of economic activity is an important factor in the context of the impact on the ecological and economic balance. The implementation of the results obtained in the adjustment of the calculations of payments for negative environmental impact is proposed: to set payments per unit of production which are not proportional to emissions, but proportional to the eco-intensity calculated according to the proposed methodology. In this case, the accumulation of harmful substances in natural environments, the added value of production and the timing of project implementation will be taken into account. This corresponds to the concept of “green” economy, which provides the growth of well-being and quality of life with the maximum possible reduction of the negative anthropogenic pressure and improvement of the quality of the environment.
