Abstract:

The properties of an open dump area are important to the application of the elements to the soils and their migrations through soil depth; therefore this study was investigated to evaluate the migration of elements in an open dump area. Soil samples were taken from three soil profiles, one of them was at an open dump site, and the second and third profiles were taken at different distances from the open dump site. In total eighteen soil sample were collected. Some soil physical and chemical properties were determined for each horizon. Total concentrations of Fe, Ni, Zn, Cu, Cr, and Cd were det

Abstract:

Soil velocity profile often used as subsurface characterization by using geophysical technic. Seismic refraction is one of geophysical technique to determine primary wave (p-wave) velocity of soil profile. In this paper, seismic refraction technique has been performed on two different types of soft soil (peat soil and RECESS clay) for comparison of its p-wave velocity soil profile. From p-wave velocity soil profile comparison, its show the peat soil has soil velocity range from 211 m/s – 534 m/s at depth of 0 – 4 m while the soft clay show soil velocity range from 248 m/s – 1842 m/s at depth o

Abstract:

Radiocarbon has been measured in two soil profiles, one of which has been covered by a building since 1956. A comparison of the Δ14C values in horizons of each profile gives an estimate of the total input of atom bomb 14C into the soil profile. From the Δ14C and carbon density profile data, the carbon input rates, respiration rates, and diffusivity are calculated. The lack of vegetation on one soil affects the mobility and the respiration rate of the soil carbon in that soil. The data from this soil profile are also used to check the assumption, used in previous analyses, that there is a unifo

The study was conducted in the Hyang-Argopuro volcanic mountain in Jember, Indonesia, with the aim of assessing the distribution of soil minerals along a toposequence and their relationship to soil genesis.

The results revealed that the predominant sand minerals in the soils are opaque minerals, weatherable minerals, amphibole groups, and ferromagnesian minerals.

A notable feature of these soils is the presence of talc and the high iron content as goethite, hematite, lepidocrocite, and maghemite. Talc was the most abundant non-iron mineral of the clay fraction of Soil II. In Soil I, talc occurs as a residual phase from the parent material with its persistence in the profile aided by coatings of iron oxides, which inhibit further weathering. In these soils there is a high proportion of

This relatively simple method requires knowledge of soil CO2 concentration profiles and soil diffusive properties.

Abstract:

The comparative geographical approach to the study of soils consists in the parallel study of soils and soil formation factors at various points and in the analysis of their relationships. Compilation of profiles can be carried out in the office (if there is sufficient cartographic material) or on the basis of special field studies. Often both of these methods are combined: profiles of smaller scales are compiled in the office, and larger scales — on the basis of special field studies. Soil formation factors were also applied to these profiles (first of all, the relief that determined th

Abstract:

The PCDD/F profiles in free-range chicken eggs and corresponding soils from private households in Vietnam were compared. The main trend in the change in the profile of PCDD/F congeners during bioaccumulation in eggs is the relative increase in the contributions of low-chlorinated congeners and the decrease in the contribution of OCDD. Differences in the profile of hexachlorinated congeners in eggs and soil may indicate additional sources of PCDD/F in eggs other than soil.

Abstract:

The soil leakage characteristics of depressions in karst areas should be explored by investigating their soil Ca and Mg contents. As a starting point, in a karst landform typical of Guizhou Huajiang dry valley karst watersheds, we selected surface depression and performed a field investigation, soil profile excavation, and soil sample collection. The soil samples were pretreated and taken to the laboratory for soil physical and chemical analysis. The data were processed, and the Ca and Mg contents of the soils were analyzed to determine the spatial variation characteristics of soil leakage in

In carbonate areas, however, deep-soil CO2 concentrations decrease and have no significant correlations with soil depth. Soil organic carbon is negatively correlated with soil CO2 concentrations in noncarbonate areas. In carbonate areas, such relationsh
