Using GPR and EM Tools for Agriculture and Forestry Research

GSSI Ground Penetrating Radar and Electromagnetic Induction Instruments in Agriculture

Geophysical professionals require a reliable and accurate means to examine soil conditions and the natural structures found beneath the surface of the earth. GSSI ground penetrating radar has long been the choice for geophysical investigations with a wide range of high precision, field-proven tools.

Measure Soil Conductivity with GSSI Profiler EMP-400

Soil scientists measure ground conductivity data for evaluating ways to remediate contaminated soils. Ground conductivity measurements are also invaluable to precision agriculture applications, where the GSSI Profiler EMP-400 is used to determine how best to apply fertilizer to farmlands and vineyards.

Profiler EMP-400 and differential GPS. Data shows areas
of high conductivity that are the result of salt intrusion
into the overlying soils.

Golf Course Maintenance with GSSI Ground Penetrating Radar

Ground penetrating radar is an invaluable tool for golf course superintendents who need to locate drainage and irrigation pipes and delineate areas of excess water saturation in greens.

Map Tree Roots and Analyze Tree Health with Ground Penetrating Radar

GSSI ground penetrating radar aids arborists in collecting high-resolution 3D GPR data images of tree root systems. Additionally, ground penetrating radar is used to measure tree trunk characteristics in order to identify potential insect and fungal infestation that can affect the tree’s health.

Locating Drainage Tiles with Ground Penetrating Radar

Locating farm drainage networks is a difficult and time-consuming task. The traditional solution was to dig or probe to find the position of drainage pipes. Ground penetrating radar provides a much faster and more accurate survey method to locate and map drainage pipes.

Two sets of farm drainage tiles located at different
depths – the top set of targets are PVC pipes, the
bottom set are clay tiles. Data collected with a
SIR-3000 and a 200 MHz antenna.
