Shallow Penetrometer Penetration Resistance [PDF]
Journal of Geotechnical and Geoenvironmental Engineering, 2015 Shallow penetrometers—such as the hemiball and toroid—were conceived as potential in situ testing devices with the ability to measure: (1) soil strength parameters during vertical penetration, (2) soil consolidation characteristics during dissipation tests postpenetration, and (3) interface friction during torsional loading.

, 2023 This dataset is comprised of penetrometer (soil resistance) data for 20 sites in South-West England. The sites are physically close but are on four different soil types. At each site a dipwell was sunk to ~85 cm and water levels measured.

Method for in-field texture analysis of sugar beet roots using a handheld penetrometer
Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2022 Methodology for analysing textural properties of sugar beet roots in the laboratory has previously been established. It has been shown to be reliable and of value in exploring relationships between textural properties, damage rates, and storability of ...

Quality improvement by application of a revised standard – feasibility studies on 2500 soundings
Acta Polytechnica CTU Proceedings, 2023 CPT is a geotechnical investigation method that, depending on the geology, has been proved to be an essential tool to establish the Geotechnical Design Model. However, doubt has been raised about the quality of the data.

A novel approach to estimate soil penetrometer resistance from water content, bulk density, and shear wave velocity: A laboratory study on a loamy sand soil [PDF]
, 2020 Continuous estimates of penetrometer resistance (Q) would be useful in root elongation and in soil management studies. However, penetrometers produce estimates of penetration resistance at discrete time points.

Evaluation of selected physical properties of soil in the vineyard
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2011 There is registered approximately 18 000 ha of intensive vineyards in this time in Czech Republic. The intensive viticulture production is represented by high amount of working operations which are practised by using of mechanization.
