On the go measurements of penetration resistance and yield and the effect of deep loosening

Sammanfattning

A horizontal, on-line penetrometer has been used on several fields in Sweden to measure penetration resistance. The yield on these fields have been mapped and compared to the penetration resistance. In some of the fields, deep loosening has been done on parts of the field in order to be able to study the effects on the yield. Some correlation of higher penetration resistance and lower yield has been found but no positive effect of the deep loosening was discovered.
