Soil compaction is one of the main negative factors that limits plant growth and crop yield. Therefore, it is important to determine the soil resistance level and map it for the field to find solutions for the negative effects of the compaction. Nowadays, high powered communication technology and computers help us on this issue within the approach of precision agriculture applications. This stu...

Abstract. 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...

We collected SH-wave seismic reflection data over a shallow aquifer in southwestern British Columbia to investigate the use of such data in hydrogeologic applications. We used this data set in developing a methodology that uses cone penetrometer data as an integral part of the inversion and interpretation of the seismic data. A Bayesian inversion technique converts the seismic amplitude variati...
