Soil samples taken in a grid pattern can be used to create soil nutrient maps. Grid samples use composite soil samples from a small area to represent a larger area in the field. This information is used to spatially apply soil amendments to a field based on need. It is important that samples taken for the application of soil amendments represent field areas correctly. The objective of this study was to use GIS to compare sampling intensity and pattern of soil pH, P and K on a 10 ha area of the Arkansas Agricultural Research and Extension Center. Soil samples from the 0 -15 cm depth were taken in a 10 by 10 m grid pattern. Different grid spacing and patterns were compared with the 10 by 10 m grid. This study shows that optimum grid sample patterns were nutrient dependent and if adequate samples were not taken then field spatial nutrient information could be misrepresented.
