Benchmark (BM) sampling of agricultural fields involves soil sampling a representative area 100 ft X 100 ft within a field. Fifteen to 20 cores are taken within the BM site to make a composite sample for analysis. This study compares results from BM and conventional sampling methods. Five samples were taken by each method from each of two contrasting fields. On the topographically more uniform field, BM samples yielded results similar to conventional sampling for nitrogen and phosphorus. Results from the two sampling methods were more similar for the uniform field than for the non-uniform field. A single set of samples, one benchmark and one conventional, taken from 13 other fields showed very close agreement between the two methods.
