Helping growers around the world achieve outstanding crops by identifying and solving nutritional deficiencies with innovative solutions.


The success of our customer's outstanding field performance is a result of using the Ask The Plant® program which identifies plant deficiencies seven to 21 days before they are visually detected. This allows our customers time to correct the issue before their crops are impacted.

With over 75 years of proprietary knowledge and experience, we are able to provide guidance to growers, nurseries, landscapers, farmers, academics, agricorps, organics, and government institutions world-wide.
