Conventional Soil Sampling

Conventional soil samples are typically taken at a rate of 1 sample per 5 acres. Each sample is composed of 10 or more soil cores taken in a “W” pattern to obtain a representative sample. After sampling is complete, maps with sample locations are emailed or mailed to the customer to allow for quick management decisions.

Grid Soil Sampling

We offer GPS soil sampling grid sizes of 1 acre, 2.5 acres, and 5 acres. A handheld PC and GPS receiver are used to collect boundaries, set grid locations and record sampling points.  Adjustments to the sampling points can be made in the field to eliminate unrepresentative sample locations within the field. Later, after samples have been tested in our lab, soil data is linked directly to the grid points and map books are created showing aerial imagery, soil types, and soil test values. The software program we use saves sample locations and test values to be used for future sampling.

VRT  (Variable Rate Technology)

From soil sample data, we are able to create VRT spreader files, nutrient trend maps and recommendation maps for customers at an additional charge. The spreader files are produced specifically for the customer’s spreader controller for quick, easy start-up.
