Click to ViewSoil compaction prevents moisture penetration, reduces fertilizer and chemical uptake and hinders plant root growth. In some cases, yield losses can run as high as 30% due to compaction. This electronic soil compaction meter is the most versatile compaction meter on the market. Soil depth readings are determined by a sonic depth sensor. Cone index values are measured by a load cell sensor and can be displayed in PSI or kPa.

  User Instructions
The instrument finds its application in geotechnical field and useful in identifying subsurface hardpan in soils. It is used to assess soil physical restrictions in soils especially claypans. Improvements in cone penetrometer design and capabilities, such as measurement of apparent soil electrical conductivity may make it a more effective tool for assisting in routine soil management decisions in claypan soils affected by compaction or application of organic soil amendments.Care should be taken to prevent the damage to the cone.
