Nodulation Assessments

A healthy-looking pulse plant in the field is not necessarily a reflection of healthy nitrogen fixation underground. Localized soil environments, particularly those with variations in soil nitrogen, can lead to vigorous growth that can hide any nodulation problems.

A plant’s potential to fix nitrogen can be evaluated by assessing nodulation and plant growth characteristics. It means the only way to see if a rhizobia-based inoculant is helping the crop properly fix nitrogen is to dig plants up and examine the roots.
