Nitrate Testing & Information
Bring in a sample Monday - Thursday, 8:00 a.m.-5:00 p.m. to get tested.
Samples of standing crops should contain approximately 20 plants (taken randomly by traversing in a zigzag pattern across a field) cut off about 4 inches above the ground. If the screening test indicates a high level of nitrate, a sample can be sent into the MSU Analytical laboratory for further testing.
