Characterization and discrimination of soils by their reflected electromagnetic energy [PDF]

Pesquisa Agropecuária Brasileira, 2002
The objective of this work was to verify if reflected energy of soils can characterize and discriminate them. A spectroradiometer (Spectral reflectance between: 400-2,500 nm) was utilized in laboratory. The soils evaluated are located in Bauru region, SP,

Tyre Configuration and Axle Load of Front-Wheel Assist and Four-Wheel Drive Tractors Effects on Soil Compaction and Rolling Resistance under No-Tillage

Agriculture, 2022
Selecting the appropriate tyre configuration and settings for heavy farm vehicles is important to ensure that soil compaction and power loss in rolling resistance are minimised and traction is optimised.

Soil shrinkage curves and micromorphology in contrasting managements [PDF]

Ciencia del Suelo, 2020
Compaction processes are generally described using methods that do not distinguish volume changes of different types and pore sizes. The adjustment of shrinkage curves (ShC) using the XP model allows elucidation of the effects of soil management on ...

Adsorption of Cd, Cu, Ni and Zn in tropical soils under competitive and non-competitive systems Adsorção de Cd, Cu, Ni e Zn em solos tropicais em sistemas competitivo e não-competitivo

Scientia Agricola, 2010
The adsorption of heavy metals in soils affects their behavior in the environment and their bioavailability to plants. The knowledge of the adsorption mechanisms in competitive systems allows a more realistic evaluation of the metals' behavior in the ...

Mapping soil compaction using indicator kriging in Santa Fe province, Argentina

Acta Agronómica, 2017
Soil compaction is a complex physical process that affects the crop performance by limiting the expansion of the roots and the reduction of water and nutrients uptake from soil.

Root abundance of maize in conventionally-tilled and zero-tilled soils of Argentina Abundância de raízes de milho (Zea mays L.) em solos de Argentina sob preparo convencional e plantio direto

Revista Brasileira de Ciência do Solo, 2008
Maize root growth is negatively affected by compacted layers in the surface (e.g. agricultural traffic) and subsoil layers (e.g. claypans). Both kinds of soil mechanical impedances often coexist in maize fields, but the combined effects on root growth ...

Estimating Sample Size of Soil Cone Index Profiles by Bootstrapping

Revista Brasileira de Ciência do Solo, 2017
Measurements of the soil cone index are widely used to assess soil resistance to root penetration (SR) and to monitor the soil compaction status of agricultural fields.

Morphological characteristics of soybean root apexes as indicators of soil compaction Características morfológicas de ápices de raízes de soja como indicadores de compactação do solo

Scientia Agricola, 2010
Plant soil compaction poses a serious problem to agriculture because it produces different types of changes in plant characteristics. No method has been implemented to date to use root morphological changes as indicators of soil compaction levels ...
