Abstract/Contents:"A new EC meter eliminates the need for preparing saturated soil extracts. The TDSTestr 4tm (Cole Parmer, P.O. Box 48898, Chicago, IL 606480898, Cat. No. 19088-30) can be probed directly into a saturated soil paste eliminating the need for vacuum filtration. To evaluate the performance of the TDS-4, thirty-two golf course greens representing six different courses were sampled. Conventional saturated soil extracts were prepared by vacuum filtration and the extract EC measured using a Horiba EC meter. The TDS-4 meter was probed directly into the soil paste prior to vacuum filtration. Regression analysis revealed a highly significant correlation between the Horiba extract and TDS-4 direct measurements (R=0.94, p<0.0001). Conversion from direct TDS-4 meter readings to equivalent soil extract values can be carried out using the following equation: saturated soil extract EC (dS/m)=0.8 + 2.7 *(TDS-4 EC [dS/m]). The TDS-4 meter also has been used in the field by probing the meter directly into moistened soils."
