Internal Reflection Sensor for the Cone Penetrometer [PDF]

, 1998
The objectives of this project are to design, assemble, test, and demonstrate a prototype Internal Reflection Sensor (IRS) for the cone penetrometer. The sensor will ultimately be deployed during site characterization with the goal of providing real-time,

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.

Application of Georadar in Areas with Different Vegetation Cover

Floresta e Ambiente, 2017
The Atlantic Forest degradation and fragmentation imposes the need for soil and vegetation assessments in order to estimate the environmental vulnerability of the remnants. The objective of this study was to evaluate the georadar applications in areas of

Soil penetrometer [PDF]

, 1968
An auger-type soil penetrometer for burrowing into soil formations is described. The auger, while initially moving along a predetermined path, may deviate from the path when encountering an obstruction in the soil.

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 ...

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).
