Soil crusting in Western Samoa. Part II - Experimental investigation of factors influencing crust formation

, 1971
The Alafua Penetrometer was used to measure relative differences in soil crust strength. Crust strength and thickness were shown to increase with increases in rainfall amount, drying time, droplet size, kinetic energy and soil clay and silt content.

Measuring mechanical impedance in clayey gravelly soils

Revista Brasileira de Ciência do Solo, 1998
Mechanical impedance of clayey and gravelly soils is often needed to interpret experimental results from tillage and other field experiments. Its measurement is difficult with manual and hydraulic penetrometers, which often bend or break in such soils ...

Seafloor Sediments, Morphologic Features, and Geotechnical Properties of Harrison Bay in the Alaskan Beaufort Sea

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Sediments on Arctic continental shelves are impacted by sea ice and ice‐related processes for up to 9 months per year. As a result, seabed morphology in cold regions can exhibit features such as ice scours which are absent on lower‐latitude shelves.

Assessing the Spatiotemporal Variability in Geotechnical Sediment Properties of Beach Cusps on a Sandy Beach

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.
Abstract This study examined the spatiotemporal variability in geotechnical properties of beach cusp sediments on a sandy beach and tested if such variability can be used for cusp monitoring from satellite imagery. Specifically, sediment properties (including moisture content (w), relative density (Dr), sediment strength (QSBC) and friction angle (ϕ ...

ESTUDIO DE LA DUREZA DEL QUESO EDAM POR MEDIO DE ANÁLISIS DE PERFIL DE TEXTURA Y PENETROMETRIA POR ESFERA STUDY OF EDAM CHEESE HARDNESS USING TEXTURE PROFILE ANALYSIS AND PENETROMETRY BY SPHERE

Revista Facultad Nacional de Agronomía Medellín, 2007
Se estudió la dureza del queso Edam a través de la técnica de penetrometría y análisis de perfil de textura (TPA). Los resultados estadísticos indicaron que la dureza del producto incrementó con el tiempo de maduración, pero estos valores dependen de la ...

IODP Expedition 362 Compressional strength (penetrometer)

, 2020
Compressional strength was measured on section halves using a Humbolt Manufacturing Pocket Penetrometer. The penetrometer is only suitable for sediment not affected by cementation (i.e., saturated, clay-rich, soft sediment).

An improved approach for estimating root elongation rate from penetrometer resistance and macropore porosity on a silty clay loam soil

The role of macropores is often ignored in classical models for predicting root elongation using soil penetrometer resistance (PR). In this study, we propose an empirical model that includes the effects of macropores and PR on maize (Zea mays L.) root ...

Discussion of ‘‘Re-Examination of Undrained Strength at Atterberg Limits Water Contents’’ by H.B. Nagaraj, A. Sridharan & H.M. Mallikarjuna [PDF]

, 2012
Having recently investigated soil strength at the Atterberg limits, the discussers read the paper by Nagaraj et al. (2012) with interest. Whilst some of the conclusions of the paper concur with those of our own work, there are other areas in which we ...

On-the-go sensor with embedded load cells for measuring soil mechanical resistance [PDF]

Ciencia del Suelo, 2020
Soil compaction is an important degradation phenomenon that can affect root growth, and consequently crop yield. Therefore it becomes relevant to have soil compaction data for future improvements on precision agriculture management.
