Abstract

Summary

The Surface Nuclear Magnetic Resonance (SNMR) Method allows direct quantification and characterization of free pore-water in the soil. SNMR measurements in densely populated areas, often cause S/R ratios of less than 1. This situation is made additionally worse when the SNMR method is used to investigate the Vadose Zone. Because the magnitude of the SNMR signal is also dependent on the strength of the magnetic field, we have build and tested an SNMR Instrument which uses the Pre-Polarization technique to improve the Data quality by up to one order.
