Magnesium-supplying power of some Finnish mineral soils

open access: yesAgricultural and Food Science, 1973
Uptake of magnesium from a sand, fine sand, muddy clay, silty clay and heavy clay soil under exhaustive cropping with perennial rye grass was studied in green house.

Compressibility of expansive soil mixed with sand and its correlation to index properties

open access: yesHeliyon
Prior research has primarily focused on Atterberg limits, void ratios, and/or water content, often disregarding the impact of coarse material percentage in the soil, which significantly affects compressibility behavior. This paper examines the effects of

Physical and chemical attributes of archaeological soils developed from shell middens in the Região dos Lagos, Rio de Janeiro, Brazil

open access: yesRevista Brasileira de Ciência do Solo, 2011
In prehistoric times, innumerous shell middens, called "sambaquis", consisting mainly of remains of marine organisms, were built along the Brazilian coast.

Improving water stability and mechanical behavior of surface clayey soil by bio-constructed barrier

open access: yesJournal of Rock Mechanics and Geotechnical Engineering
Soil erosion induced by water is one of the most common natural disasters. Microbially-induced calcite precipitation (MICP) technique was investigated as a possible method for improving soil hydro-mechanical characteristics against erosion. Although many

The use of LANDSAT-1 imagery in mapping and managing soil and range resources in the Sand Hills region of Nebraska [PDF]

open access: yes
The author has identified the following significant results. Evaluation of ERTS-1 imagery for the Sand Hills region of Nebraska has shown that the data can be used to effectively measure several parameters of inventory needs.

Effect of Sand Addition on Laterite Soil Stabilization

open access: yesMaterials
Lateritic soils, particularly abundant in tropical regions, have been successfully used in the construction of unbound layers of flexible pavements in Brazil since the 1970s. Despite their potential, these soils are often discarded or only recommended after stabilization processes, based on traditional parameters such as gradation requirements and ...

A study of soil nailing in sand

open access: yes, 1993
This dissertation is concerned with a study of soil nailing, in particular the interaction mechanism between the soil and a nail and the failure mechanism and suitable design procedure for nailed slopes in sand. The interaction mechanism of a nail was studied by carrying out a number of pull-out tests, direct shear tests of nailed sand and interface ...

Critical roles of short‐range‐order minerals in shaping soil water retention curves in volcanic regions

open access: yesVadose Zone Journal
Predicting water retention is difficult for highly aggregated volcanic soils (Andisols) with heterogeneous pore size distribution. This paper aimed to examine how andic materials influence soil water retention based on soil composition.
