| Abstract/Contents: | "Soil testing is one of the most commonly used means of estimating the nutritional status of turfgrass and of estimation of the fertiliser requirements to maintain a healthy sward." All users of soil tests, however, should be aware of "some possible, and very common, sources of error. Soil testing is an extremely useful tool, and one of the most reliable and easiest means of estimating turf nutritional status. However, it can quickly lose its credibility as a diagnostic tool if serious errors are commonly discovered, and if these errors lead to the wrong fertiliser applications. Whether you apply too much of a paticular fertiliser, or too little, may often depend on simple errors arising from the soil test... Probably the largest source of error in any soil test program, and the hardest to minimise" is sampling." It is implicit that many small samples should be taken from each unit and pooled to make a composite which represents the unit... The drying process is another major source of error in soil testing. Whether the soil is transported to the laboratory in a moist or dry state, whether the temperature of the sample is controlled, and whether the sample is allowed to 'sweat' or 'breathe', will all affect the final results of the soil test." Errors can also occur during the chemical analysis. "The greatest source of error in the chemistry laboratory is generally caused by the use of non-standardised chemical testing procedures. A great deal of confusion is also caused by the use of a wide range of units for reporting the results. Both of these sources of error and confusion can be minimised by standardizing both the laboratory procedures and the reporting of results, a process which is currently being pursued by all testing authorities... Generally, the closer a laboratory conforms to the exact methodology for a paticular extraction, then the less likelihood there is of errors occurring in the process." |
