Collect enough of a representative tissue subsample from the weighed plant tissue to fill a quart-sized plastic bag. Submit sample to a plant analysis lab for total nitrogen (N) and dry matter analysis.

Percent total N for plant tissue typically ranges from 0.5% to 5.5%. If your value falls outside of this range, call your lab for clarification.

We discourage using table values or rough estimates in place of lab results, as tissue N concentration can vary widely within a single plant species.

Go to "Tissue Sampling Instructions" for more information on how to prepare and submit plant tissue samples for analysis.
