Abstract:
Soil bulk density is a physical property of soils that affects water storage, water and nutrient movement, and plant root activity in the soil profile. The ability to quantify soil bulk density using vibration-induced conductivity fluctuation was investigated with possible field applications in the future. The AC electrical conductance of soil was measured using a pair of blade-like electrodes while exposing to periodic vibration. The blades were positioned longitudinally and transversally to the direction of the induced vibration to enable the calculation of a normalized index. This normalize

Abstract:
Soil compaction in alfalfa fields has become increasingly severe due to the mechanization of animal husbandry and the increased use of heavy agricultural machinery. Perennial alfalfa land undergoes mechanical compaction several times during the planting period without mechanical tillage. The compacted soil structure may recover through moisture changes, freezing and thawing cycles, and plant growth, but the extent and rate of this recovery remain unknown. In this study, alfalfa plots with two different soil types (medium loam and sandy) in Gansu, China, were selected to address these issues. T

Abstract:
Concern about soil physical quality has grown in recent years, particularly in view of serious problems caused by intensive soil use. We hypothesised that improper soil management in irrigated areas damages the structure of sensitive soils in some regions in North-eastern Brazil. The aim of the study was to evaluate the physical quality of irrigated soils planted with annual and perennial crops, compared with soils under natural vegetation in Ceará State, Brazil. Measurements were made of least limiting water range (LLWR), the S index, and relative density. Undisturbed soil samples were collec

Abstract:
In road works, there are cases in which natural soils have inadequate characteristics for their intended use, especially clayey or fine ones, which leads to the need to find stabilization methods that allow the soil to present itself as a suitable material for its application. Thus, the ash, residue generated in the sugar and alcohol industry from the burning of sugarcane bagasse and which often does not have an adequate destination, becomes an attractive material due to its granulometry and chemical composition. Thus, the objective was to study the feasibility of correcting the granulometric

ABSTRACT The aim of this study was to assess organic matter and physical-hydric attributes of an Oxisol under a clonal planting of eucalypt and an abandoned pasture in comparison to a successional forest with its soil under natural conditions at Paragominas municipality, southeast region of the state of Pará. In July 2013, soil samples were collected at the depths 0-0.15 and 0.15-0.35 m, which were used for the determination of the following attributes: organic matter content; soil bulk density; porosity, soil water retention and S index. In field, soil water infiltration tests were performed.

Abstract:
The issue of the land degradation vulnerability index (LDVI) is multifaceted, encompassing climate, soil, vegetation, policy formulation, and human actions. In Vietnam, the convergence of climatic fluctuations and human impact results in phenomena, such as soil sealing, erosion, salinization, and landscape fragmentation. These phenomena are recognized as significant triggers of land degradation. This paper seeks to present a method for assessing a land's susceptibility to degradation by utilizing ten ecological 10 criteria: NDVI; slope; bulk density (cg/cm3); cation exchange capacity in the so

Abstract:
Forest soil biodiversity, which drives natural ecosystem multifunctionality, can be altered by incorrect forestry management practices. Pinus laricio is the most representative and widespread conifer species in Calabria, South Italy, and appropriate management is needed to maintain Pinus laricio forest for its great economic and natural value. In Europe, thinning is considered the most effective silvicultural treatment to maintain/increase the ecological value of coniferous stands. In this study, moderate thinning (MT), intense thinning (HT), and clear cut (CC) treatments were used to manage P

The principal objective in geotechnical testing is to know the properties and behavior of soil as an engineering material. The performance of soil in engineering practice is greatly influenced by the natural environmental conditions and conditions imposed by construction of structures. The aim of soil testing is to obtain reasonably representative values of the soil properties that are reliable and have direct and significant bearing upon the solution of the practical problems involved especially in various aspects of civil engineering.

Abstract:
Different types of natural aggregates (gravel, crushed stone, sand) are used in the construction of load-bearing layers of pavement structures, the granulometric composition of which has a great influence on the compaction and load-bearing capacity of the layer. Special care should be taken when compacting single-grain materials, such as sand, as difficulties can be expected with these. For this reason, it is useful to modify the granulometric composition of the sand by adding new material of finer fractions. The bearing capacity of mixtures for the production of unbound load-bearing layers of
