Trace Element Content in Soils with Nitrogen Fertilisation and Humic Acids Addition

Agriculture, 2023
Application of mineral fertilisers can entail an increase in trace element content in the soil. In consequence, their elevated uptake by plants and transfer to further trophic chain links may occur.

Spodosols pedogenesis under barreiras formation and sandbank environments in the south of Bahia Pedogênese de espodossolos em ambientes da formação barreiras e de restinga do sul da Bahia

Revista Brasileira de Ciência do Solo, 2010
Morphologically differentiated Spodosols usually occur in the Coastal Plain of the South of Bahia and North of Espírito Santo. They are found in profiles known as "muçungas", i.e. sandy soils that accumulate water. In these areas, two kinds of Spodosols,

Characterization, agricultural potential, and perspectives for the management of light soils in Brazil [PDF]

Pesquisa Agropecuária Brasileira, 2016
Light soils occupy 8% of the Brazilian territory and are especially expressive in the new and last agricultural frontier in Brazil: the Matopiba region - in the states of Maranhão, Tocantins, Piauí, and Bahia -, where they represent 20% of the area ...

Two-dimensional study of the inclusions of skirt sand and deep cement piles to improve the load‒displacement behavior of circular foundations on soft clay soil

Heliyon, 2023
The bearing capacity of clayey soils is low, and the induced settlements play an important role in estimating the stability of structures built on these weak soils. Therefore, these clayey soils need improved mechanical strength.

SAND AS A SOIL STABILIZER

Bulletin of the Geological Society of Greece, 2017
Clayey soils often exhibit undesirable engineering behaviour such as low strength, swelling and shrinkage characteristics etc. To improve these properties, the common method followed is stabilization. An experimental program carried out in this study aims to highlight the physical mechanisms of stabilization of an expansive soil by adding an inert ...

Effects of high temperature processes on physical properties of silica sand [PDF]

, 2013
High temperature processes may alter soil properties, creating potential risks of subsidence, erosion and other hazards. Soils may be exposed to high temperatures during some aggressive contaminant remediation processes as well as natural events such as ...

Boreal Sand Hills are Areas of High Diversity for Boreal Ants (Hymenoptera: Formicidae)

Diversity, 2019
The boreal forest in Canada comprises a wide variety of ecosystems, including stabilized (overgrown) sand dunes, often referred to as sand hills. Globally, sandy soils are known for supporting a high diversity of invertebrates, including ants, but little

Surfactant and irrigation impacts on soil water content and leachate of soils and greenhouse substrates

Agrosystems, Geosciences & Environment, 2021
Water retentionx is considered an important characteristic for determining the efficiency and effectiveness of soils and greenhouse substrates. Surfactants have the potential to improve water infiltration and distribution uniformity throughout the soil ...

Assessment of Soil Tunnel Interaction in Sand Soil

IOP Conference Series: Materials Science and Engineering, 2019
Abstract In this study, series of shaking table tests were carried out to investigate the effect of tunnel model depth and direction of ground acceleration on the ground surface settlement and the dynamic earth pressure on the tunnel wall. Box tunnel model is embedded in dry and saturated soil (Karbala Sand).
