extensionpublications.unl.eduSoil nitrate-N can be estimated by sampling soil with a single 0–2 foot sample. A default value for the 2 foot depth of 3.0 ppm is suggested for medium and fine textured soils and 1.5 ppm for sandy soils. The depth-weighted average is then calculated as the sum of the nitrate-N concentration for 0–2 ft depth soil sample

Soil Sampling Guidelines - Purdue University
www.extension.purdue.eduSoil 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).
