Sonic Bloom??

[Janice M. Glime]

If the "control" was no bird song and no nutrient spray, then I would
expect just those results.  Adding nutrients to the air should increase
those in the soil and increase concentration in uptake from the soil.
Nutrients are not generally taken up from the air, unless they are talking
about bryophytes!
