| Abstract/Contents: | "North Dakota State University scientists investigate the use of TDR (time domain reflectometry)-tension infiltrometry methods to predict rootzone water content and movement. The studys findings include: Adjusting the wetting solution and procedures provides little improvement in the consistency of results for the current testing methods for putting green materials predominant in sand. Expanding the capillary porosity test to water release curve provides more information on hydraulic properties of the rootzone materials. One of the advantages is the prediction of total water and air capacity in the whole rootzone. In TDR-infiltrometer method water retentions and water conductivity are measured simultaneously. This eliminated the compaction after water retention measurement and before water conductivity measurement as in the traditional procedures. Measurement with TDR-infiltrometer is conducted in unsaturated range and reduced the effect by degree of saturations. Devices used in TDR-infiltrometer method are specially manufactured instruments and are more accurate and consistent than traditional methods." |
