Adsorptive Equilibrium

Soil has many functions in sustaining life. The prerequisite conditions for proper soil functioning may be expessed in terms of quality. Chemical quality of soil is predominantly determined by behaviour of compounds in soil. Compound behaviour is the result of the interactions of properties of the compounds and of the soil system under consideration. These can satisfactorily be described by applying methodical rules as derived in soil chemistry and soil physics. This is elaborated with examples referring to the static situation prevailing at adsorptive equilibrium, and to the dynamic situation of compound displacement in soil. The variability of soil properties appears to be of major concern. In these examples, attention is limited to the behaviour of cadmium in soil.

Air pollution by heavy metals in the urbanized surroundings presents a serious threat to human health and the environment. Road dust is distinguished as a high-level pollutant and characterized by a significant content of heavy metals. Green spaces play a leading role when it comes to improving the quality of atmospheric air in megalopolises. They trap pollutants. Most of them settle on the surfaces of plant leaves, but some can be also absorbed through the stomata. As a result of these processes, pollutants, along with fallen leaves, can later migrate to other components of the ecosystem. An important component of this system is forest litter that plays a kind of trigger role by regulating the directions of substance flows in the “leaves-litter-soil” system, keeping chemical elements from leaching out and evenly distributing their inflows. Thus, forest litter functions as a sort of biogeochemical barrier and plays a leading role in the ability of ecosystems to self-regulate. Thus, the purpose of this work was to assess the role of green spaces in improving the quality of atmospheric air in the urban surroundings and to conduct a preliminary assessment of the features of the processes of heavy metals transformation within the forest litter. The model site of research is located within the territory of Holosiivskyi forest, a part of the Holosiivskyi National Nature Park (Kyiv). The content of heavy metals in the forest litter was determined using the methods of atomic absorption spectrophotometry. The results of the study of Cu, Ni, Pb, Cd, Cr and Zn content annual dynamics within the forest litter of the hornbeam forest of the Holosiivskyi National Nature Park show that the maximum concentrations are typical for the summer period, when the litter reserves sharply decrease, and the minimum ones – for the autumn-winter period during their accumulation. Comparison of the distribution of heavy metals content within the leaf and fermented layers showed that, under the conditions of the model area, Zn, Cu, and Ni are predominantly accumulated right in the leaf layer of the forest litter. Moreover, it was revealed that the processes of leaf litter mineralization lead to migration of Cu, Ni, Pb, Cd and Cr, and setting of Zn.

Questions of creation the environmentally friendly agricultural land as a priority direction of greening the economy of regional system are considered. The role of environmentally friendly land as part of a balanced agricultural nature, quality characteristics which are the basis of agro-ecosystems preservation, productivity increasing, prevent degradation and agricultural landscapes restoration is analyzed. The article presents the issue of improving soil quality continues needs to be urgent. In particular, the task of improving the quality of agricultural land and considering the qualitative characteristics as an object of management remains unresolved, which necessitates further systematic research in this direction. The purpose of the article is to substantiate the essence of soil quality management, the creation of land masses with appropriate soil characteristics as a means of obtaining safe products of standardized quality, maintaining the quality of the natural environment, preventing its degradation and using innovative industrial technologies in alternative agricultural systems. It is substantiated that qualitative soil properties and fertility are inextricably linked. The processes of soil formation and soil fertility are determined by a number of natural factors and the nature of economic activity, which affects not only the arable layer but also deeper soil horizons, as well as groundwater and groundwater. The optimal parameters of fertility indices should be established for each type of soil, ie they can vary according to the fertility patterns as a combination of soil properties and modes that ensure the productivity of the land, the high quality and safety of the agricultural products derived from them. It is determined that the management of ecological agriculture will facilitate the creation of land uses with special characteristics, which are achieved through the implementation of the general laws of agriculture and a number of principles, among which the principles of environmental orientation are combined with the principles that facilitate their implementation.

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.

Abstract. The condition or quality of soils determines its ability to deliver a range of functions that support ecosystem services, human health and wellbeing. The increasing policy imperative to implement successful soil monitoring programmes has resulted in the demand for reliable soil quality indicators (SQIs) for physical, biological and chemical soil properties. The selection of these indicators needs to ensure that they are sensitive and responsive to pressure and change e.g. they change across space and time in relation to natural perturbations and land management practices. Using a logical sieve approach based on key policy-related soil functions, this research assessed whether physical soil properties can be used to indicate the quality of British soils in terms of its capacity to deliver ecosystem goods and services. The resultant prioritised list of physical SQIs were tested for robustness, spatial and temporal variability and expected rate of change using statistical analysis and modelling. Six SQIs were prioritised; packing density, soil water retention characteristics, aggregate stability, rate of erosion, depth of soil and soil sealing. These all have direct relevance to current and likely future soil and environmental policy and are appropriate for implementation in soil monitoring programs.

The study evaluates and compares two procedures for selecting soil quality indicators (used for the construction of soil quality indices, SQI) by using diverse chemical, physical, and biological properties, and evaluates the role of soil microbiological properties in the construction of SQI. Different soil environments were selected from an extensive agricultural production site in the rolling pampa, Buenos Aires, Argentina. The plots included an undisturbed soil, a grassland soil, and continuous tilled soils with four different surface horizon depths (25, 23, 19, and 14 cm). Various properties were measured, and a minimum dataset was chosen by principal component analysis (PCA) considering all measured soil properties together (procedure A), or the PCA was performed separately according to classification as physical, chemical, or biological soil properties (procedure B). The measured soil properties involved physical, chemical, and biochemical properties determined by standard protocols used in routine laboratory analysis (simple SQI, SSQI) or more laborious protocols to determine microbial community structure and function by phospholipid fatty acid (PLFA) and catabolic response profile (CRP), respectively (complex SQI, CSQI). The selected properties were linearly normalised and integrated by the weight additive method to calculate SSQI A, SSQI B, CSQI A, and CSQI B indices. Two microbiological SQI (MSQI) were also calculated; MSQI 1 considered only biological properties according to the procedure used for calculating SQI; MSQI 2 was calculated by considering three selected microbiological parameters representing the size (microbial biomass carbon), activity (soil basal respiration), and functional diversity (evenness, determined by CRP) of the microbial communities. All of the constructed indices show the same differences among the study sites. The inclusion of CRP and PLFA data in the indices slightly increased, or did not increase, the index sensitivity. Microbiological indices had the same sensitivity as the indices integrated by physical, chemical, and biological properties. An evaluation of the SQI constructed by both procedures found no difference in sensitivity. However, SQI constructed by procedure B allowed evaluation of the effects of management practices on physical, chemical, and biological soil properties.

AbstrakKehadiran tumbuhan bawah pada hutan tanaman jati dapat memberikan dampak positif yaitu, menjadi sumber keragaman hayati, menciptakan iklim mikro di lantai hutan, menjaga tanah dari bahaya erosi, serta dapat memelihara kesuburan tanah. Namun keberadaannya seringkali dianggap sebagai kompetitor bagi tanaman yang dibudidayakan. Hutan Pangkuan Desa (HPD) Pitu telah dikelola secara intensif oleh masyarakat yang dilakukan baik di bawah maupun di luar tegakan sehingga diduga mempengaruhi kondisi ekosistem di kawasan tersebut baik terhadap kelimpahan tumbuhan bawah maupun kualitas kimia tanahnya. Tujuan penelitian ini adalah untuk mengetahui keanekaragaman jenis tumbuhan bawah dan kualitas kimia tanah pada berbagai tipe penutupan lahan di HPD Pitu, BKPH Getas. Pengamatan dilakukan dengan menempatkan petak kuadrat berukuran 1 m x 1 m sebanyak 5 petak pada setiap unit lahan secara random. Hasil penelitian menunjukkan pada 4 (empat) penutupan lahan yaitu hutan, semak, ladang, dan pemukiman didominasi oleh jenis yang berbeda tetapi komposisi komunitas pada hutan dan semak memiliki similaritas yang relatif tinggi. Kualitas kimia tanah pada berbagai penutupan lahan tidak berbeda secara signifikan. Aktivitas masyarakat yang tinggi pada berbagai penutupan lahan diduga menjadi penyebab rendahnya hara pada berbagai tipe penutupan. Kondisi keharaan yang miskin hara khususnya pada kawasan hutan tentu akan memengaruhi produktivitas tegakan jati yang merupakan tanaman pokok di kawasan tersebut. AbstractThe presence of undergrowth on teak plantations can have a positive impact i.e, a source of biodiversity, creating a microclimate on the forest floor, keeping the soil from the erosion, and can maintain soil fertility. On the other hand, its existence is often regarded as a competitor for cultivated plants. Hutan Pangkuan Desa (HPD) Pitu has been intensively managed by communities undertaken either below or outside the stand so that it is suspected to affect the ecosystem condition in the region both to the abundance of plants and quality of soil chemistry. The purpose of this study was to determine the diversity of undergrowth species and soil chemical qualities in various types of land cover in HPD Pitu, BKPH Getas. The observation was done by placing a 1 m x 1 m square plot of 5 plots on each unit of land. The results showed that 4 (four) land closures i.e forests, shrubs, dry farmland, and settlements were dominated by different species but the community composition in forests and shrubs had a relatively high similarity. The soil chemical quality at various land coverings did not differ significantly. High community activity in various land closures is thought to be the cause of low nutrients in various types of closure. The nutrient-poor condition of the forest, especially in the forest area, will affect the productivity of teak stands, which are the staple crops in the area.

Arable Soils

Arable soil is a functional unit whose condition is vital to crop production, but also to ecosystems at large owing to the significant role of soil in global nutrient cycles and balances. The soil quality concept recognises the concern for the sustainability of current arable land use practices. It integrates soil chemical, physical and biological properties, and takes account of the interaction of soil with water and air. This paper reviews the soil quality concept and its applications and discusses the importance of the concept for the assessment of Finnish arable soils. Many aspects of the chemical quality of arable soil are already well known in Finland. In contrast, follow-up of the physical and biological soil components, which are increasingly seen as important features of soil quality, is rudimentary. For monitoring of the soil quality at different scales – field, regional, national and global – a suitable set of indicators needs to be identified. In this paper particular attention is paid to the potential importance and usefulness of selected biological indicators. It is clear that more basic research is needed to provide scientists and advisors with a solid basis for transmitting reliable information on soil quality. While the soil quality concept has been justifiably criticised, it has clear merits in the integrated handling of the soil entity and in highlighting the environmental aspects of arable soil quality.;
