Soil sampling for whole-field management The goal of soil sampling for whole-field management is to get a sample representative of the typical soil in the field. To do this, subsamples are distributed across large areas to ensure the entire field is represented. To achieve this, collect composite samples in a zig-zag pattern (Fig. 3).

Soil sampling is the foundation upon which the entire soil testing/nutrient management planning process rests. If the foundation is bad (soil sampling technique), the integrity of the whole house built upon this foundation is questionable (nutrient management decisions). As a result, it is very important that the people collecting soil samples be
