SOil Sampling

At Marshfield Ag Service we offer a wide variety of sampling options to help you manage your fields. Our two automated sampling units are equipped with GPS for creating field boundaries and grid sampling.  Select the grid size that meets your farm’s needs.  Other in-season sampling options include:  Pre-plant and Pre-siddress nitrate testing, Plant tissue testing, Soil pathogen testing, Cyst nematode testing, and much more.  Get your nitrate tests back the same day they are taken with our 360 Soil Scan.
