They applied a nutrient solution containing 11.25 atomic% N15, and a week later only about 1/10 of that was detected in the plant itself.

Now that’s crop science!

That video wouldn’t be available to the public, would it?

Don’t stress if you can’t find it, Ray—I appreciate your efforts nonetheless.

I found a paper that looks very similar to what you had described: the link below should bring it up.

The Uptake and Partitioning of Nitrogen in Phalaenopsis Sogo Yukidian ‘V3’ as Shown by 15N as a Tracer in: Journal of the American Society for Horticultural Science Volume 138 Issue 3 (2013).

Thanks again!
