Internal Reflection Sensor for the Cone Penetrometer [PDF]

, 1998
The objective of this project is to fabricate and demonstrate an internal reflection sensor (IRS) prototype for the cone penetrometer. The IRS is a sensor that responds in real-time to almost any subsurface liquid contaminants. The IRS utilizes the variations of refractive index of different liquid contaminants as a sensing scheme.

Calibration chamber tests of a cone penetrometer in sand

Géotechnique, 1988
The results of a series of tests using a cone penetrometer in sand in a large calibration chamber are reported. Sand at three different densities and a range of stress states was studied. The principal finding from the tests is that cone resistance in sand depends primarily on the horizontal stress and the angle of friction but is relatively ...

Farming practices and their effect on soil moisture and penetration resistance: Impact on maize yields in rainfed agriculture

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract In sub‐Saharan Africa, there is growing interest in conservation agriculture practices, including reduced tillage (e.g., ripping), residue retention, and crop diversification, but their effects on soil moisture and penetration resistance in sub‐humid regions remain unclear.

Effect of Chitosan, Aloe vera Gel and Coconut Oil Edible Coatings on Postharvest Quality and Shelf Life of Strawberry (Fragaria × ananassa Duch) Under Ambient Storage

Food Science &Nutrition, Volume 14, Issue 6, June 2026.
Postharvest application of eco‐friendly edible coatings consisting of chitosan solution (CH), Aloe vera gel (AVG), and coconut oil (CO) on strawberry fruit under ambient conditions. Six distinct formulations (CH, AVG, CO, CH + AVG, CH + CO, and AVG + CO) along with a distilled water (control) were analyzed.

Soil Property Responses to Push‐Pull Cropping in East Africa

Food and Energy Security, Volume 15, Issue 3, May/June 2026.
ABSTRACT Push‐pull technology is increasingly promoted in sub‐Saharan Africa, particularly for pest management and enhancing crop productivity. However, its influence on soil properties remains understudied, despite its potential implications for soil health and sustainable soil fertility management. This study examines soil properties in push‐pull and

Use of the Dynamic Cone Penetrometer in Compacted Clay–Sand Layers

Applied Sciences, 2022
The ASTM D6951 suggests a test method using the dynamic cone penetrometer (DCP) for the assessment of shallow pavement strength. This study is dedicated to evaluating a similar test method to be used for fine-grained clay–sand mixtures, which are ...

Soil physical quality index under long‐term organic no‐tillage management in central Ohio

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Understanding how long‐term organic inputs and no‐tillage (NT) management influence soil physical quality (SPQ) is essential for sustainable agriculture. This study assessed the impacts of compost, manure, and cover cropping on the soil physical quality index (SPQi) after 27 years of NT management under a long‐term cropping system in central ...

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 strength properties of stabilized soils using dynamic cone penetrometer test

Open Engineering, 2023
The subgrade soil layer is the most essential part of the pavement system. Many pavement failures can be associated with subgrade weak strength and stiffness qualities.

CALIBRATION OF A MANUAL CONE PENETROMETER USING A DIGITAL PENETROLOGGER

American Journal of Agricultural Science, Engineering, and Technology, 2017
Cone penetrometers standardized by American Standards for Agricultural Engineering (ASAE) have been major instruments for investigating and quantifying soil compaction. However, the continuous use of penetrometers often introduces errors to the Cone Index (CI) readings obtained from the instruments over time.
