Checking Roots for Effective Nodulation

To check for effective nodulation two to four weeks after germination, carefully dig around and remove several plants. Then wash the roots in a bucket of water. Look for nodules and examine their distribution. Effective nodules generally are clustered around the taproot. Slice and observe the interior of several nodules. Nodules that have been actively fixing nitrogen have a red or pink interior. Nodules with white or pale-green interiors are ineffective.
