| Abstract/Contents: | "One of the most important factors in soil testing is selecting a good representative soil sample. The sample must accurately reflect the nutrient status of the area being sampled. Sampling instructions usually call for separating each location being sampled into uniform areas and collecting a composite sample within each area. An important question that sometimes arises is how many subsamples are needed for a representative composite sample. For turfgrass, sampling instructions from different sources vary from 5 to 20 or more subsamples per composite sample. The objective of this experiment was to evaluate natural soil nutrient variation in a uniform turf area and determine the minimum number of subsamples required for a representative composite sample. A 2,000 m2 turf area behind the Virginia Tech Research Center Laboratory in Blacksburg, VA was selected for the study. The area had received minimal fertilization and liming for over 10 years prior to the study. Grid sampling for pH, P and K identified unique areas significantly higher or lower than the average value. Large differences were found in coefficient of variation depending on the number of subsamples/- composite. Recommendations are made regarding optimal sampling strategies based on the results of this study." |
