 Synergy’s Impact
Penetrometer is based on the research of Jeff Herrick and Tim Jones as
published in A Dynamic Cone Soil Penetrometer for Measuring Soil
Penetration Resistance (Herrick and Jones 2002). Synergy’s
penetrometer reflects several refinements including a removal device,
precise drop height settings, and vibration-resistant junctions. These
refinements have been made in close coordination with Jeff Herrick and his
lab. The
importance of soil compaction is well known, but the inadequate
availability of cost effective, repeatable methods to measure soil
compaction has limited its potential use on agricultural and range lands.
Synergy’s soil penetrometer is an easy to use, inexpensive tool to measure
soil compaction, even in heavily compacted rangeland soils. Soil
compaction is determined by the work needed to push a penetrometer cone
into the soil with successive blows. The penetrometer can be used to
monitor changes in soil condition in response to management and to
identify where more detailed measurement of soil properties are required.
The penetrometer is sensitive to changes in soil moisture and texture and
therefore cannot be used as a substitute for direct measurement of soil
bulk density. Key features:
