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

www.nrcs.usda.govSampling Guidelines Important: When, where, and how deep to sample and how many samples to take is primarily dependent on the questions being asked or problems being addressed by the farm or land manager. When to sample? Timing of sampling is important, because soil properties vary within a season and with manage-ment operations, such as tillage.
