Resumen
The results of this study indicate the importance of groundwater flow and water table depth on the genesis, characteristics and distribution of soils within a hummocky morainal landscape. Non-saline and non-carbonated soils in upland depressions can be attributed to "depression-focused" recharge by snowmelt and snowmelt runoff in the spring, as evidenced by deep sola and/or eluvial horizons. Non-saline and carbonated soils on lower slopes adjacent to depressions are associated with local discharge and/or lateral flow from the adjacent groundwater mounds under the depressions in spring, as well

Resumen
This paper investigates the potential for carbonating reactive magnesia (MgO) to serve as a more sustainable soil stabilization method by providing rapid and significant strength development of the stabilized soil through absorbing substantial quantities of CO2. Gaseous CO2 was forced through laboratory-prepared reactive MgO-treated soil samples in a triaxial cell set-up, and their resulting mechanical and microstructural properties were investigated using unconfined compressive strength, X-ray diffraction, and scanning electron microscopy. The results showed that adequately carbonated MgO-tre

Resumen
Pollution from uranium, thorium, and radium poses significant environmental and public health risks. This study examines two regions with distinct soil types: carbonated and marshy soils. Soil samples were selected based on carbonate (28.83% and 9.79%) and organic matter content (22.6% and 1.8%). The research aims to evaluate the role of carbonates and organic matter in retaining radioactive elements and to identify which metal (thorium, uranium, or radium) is most retained. The methodology included physicochemical soil analysis and sorption experiments, varying pH and organic carbon (humic ac

Resumen
Carbonated water (CW) application has enhanced yields of tomato. However, little is known about the mechanism of this response. Our objectives were to determine if strawberry would respond to CW application and the effect of soil pH modification on the expression of a yield response. Two different soils were used; a calcareous soil (5% CaCO3, pH 7.9), with a Zn content 0.8 ppm and a non-calcareous soil (< 1% CaCO3, pH 6.5) with a Zn content 8.8 ppm. The carbonated water temporarily lowered the pH of the calcareous soil to 6.7 and the non-calcareous soil to 5.9, at both extremes of the optim

Soils in semi-arid regions may behave in significantly different ways than apparently similar soils in temperate climates. High risks may occur when extrapolating the behaviour of well-known soils in temperate climates towards apparently similar soils in semi-arid conditions. Such so-called “problematic soils” need to be properly identified and their specific behaviour acknowledged in design and construction methods to avoid geotechnical failures and large-scale losses.

The rate of biodegradation of hydrocarbon contaminated soils can be studied using the radiocarbon (14C) content of CO2 efflux from the ground surface over an impacted area.14C is used as a tracer to distinguish modern 14C CO2 from natural respiration processes and 14C depleted CO2 derived from petroleum degradation. Studies have shown that this analysis provides reliable, quantifiable data and an effective means of correcting for background CO2 which may present some natural depletion from older subsurface organics.

Resumen
Over half of the carbon (C) taking part in the global C cycle is held in terrestrial systems. Because of the sensitivity of the C cycle to changes in such soil-based pools of carbon, it is important to understand the basic mechanisms by which soil C is stored and cycled between the range of di erent pools which occur belowground. In the context of climate change mitigation, it is considered that increasing soil-based stocks of C, either by reducing losses from soils, or by actively sequestering new carbon, is a potentially important strategy .

Resumen
Soil analysis provides information about the quality of the soil and the input of nutrients that are needed to make the soil better and obtain a high crop yield. The research in this paper included the analysis of fertility parametars of soil in wider territory of the Požarevac city during 2017 and 2022 year. Soil analysis shows that average soil acidity, i.e. its pH value of the aqueous soil solution (pH – H2O), in 2022 was reduced by 0.28 compared to 2017. On other hand, the substitution acidity (pH – KCl) was reduced by 0.49 after 5 years. The results for CaCO3 show that the soils are gener

Resumen
The article presents a study of the magnetic susceptibility of soils as a diagnostic indicator of pedogenesis processes. The dependences of this indicator on other soil properties, such as electrical resistivity, soil acidity, content of humus and exchangeable cations, carbonates, silt and physical clay, gross iron, and soil age have been revealed. A positive relationship has been established between the magnetic susceptibility of soils and the content of carbonates, exchangeable bases, physical clay and silt. Moreover, in the depressions of paleocryogenic complexes there were more positive co

Resumen
Preferential flow appears to be the rule rather than the exception in field soils and should be considered in the quantitative description of solute transport in the unsaturated zone of heterogeneous formations on the field scale. This study focused on both experimental monitoring and computer simulations to identify important features of preferential flow in the natural environment. The specific objectives of this research were: (1) To conduct dye tracing and multiple tracer experiments on undisturbed field plots to reveal information about the flow velocity, spatial prevalence, and time evol

This field and laboratory guide describes the field and laboratory methods used to characterize blue carbon in seagrass meadows. It was developed for the Caribbean Carbon Accounting in Seagrass project and describes the protocols and methods used by the network. In brief, at each project site, seagrass abundance, species composition, canopy height, and sediment type were assessed at sixteen 0.25 m2 quadrats placed at random locations within the site. Eight 20 cm diameter cores were taken to assess seagrass biomass, shoot density, and to provide the material for assessing seagrass carbon and nu

Resumen
The pH of solutions found under disbonded polyethylene tape coatings in the field is generally in the range of 6.5 to 7.5. Electrochemically determining corrosion rates for pipeline steels exposed to neutral pH solutions in this pH range indicate that corrosion rates are too low to account for the observed crack growth rates from field excavation programs. This suggests that for the SCC process to be based on a simple dissolution mechanism then the pH at the crack tip would have to be lower than the bulk solution pH. A computer model was developed to determine solution chemistry changes within

Resumen
Although nitrate fertilizers are critical for enhancing crop production, excess application of nitrate fertilizer can result in ground water contamination leading to the so called "nitrate problem". Health and environmental problems related to this "nitrate problem" have led to serious concerns in many parts of the world including the United States and Israel. These concerns have resulted in legislation limiting the amount of nitrate N in drinking water to 10mg/g. Development of a fast, reliable, nitrate sensor for in-situ application can be extremely useful in dynamic monitoring of environmen
