It is critical that we are careful, not casual, when sampling soils. Many dollars of fertilizer decision rest upon a good soil sample. Several years ago, I was curious about the influence of the number of sample cores that comprise a composite soil sample. A review of several soil-sampling publications at the time recommended anywhere from 8 to 20 individual cores should comprise the sample. So I endeavored to look at the statistics behind this suggestion. What I discovered will be discussed in this article.
