Nutrient recommendations

Cornell University's research-based nutrient guidelines for both soil and plant tissue (tree- and small-fruit leaf and grape petiole) are available through Agro-One Services. If you wish to receive fertilizer recommendations, please submit your soil or plant tissue samples and payment directly to Agro-One.

Agro-One will honor previously purchased Cornell soil test bags. But these bags are no longer for sale.

Please visit the Agro-One website to learn more about their services, sampling instructions, submission forms, and pick-up locations throughout the Northeast.
