Potatoes planted in yard -- with an experiment

Today I planted out 12 x Kennebec (north of the broccolis) and 12 x AC Chaleur (south of the broccolis) in the central bed.  A few days ago (on May 4th) I had cut some in half, and they look to be sealed over now.

In each potato hole, I added 1 Tbsp kelp, 1/2 Tbsp azomite, 1/2 Tbsp mrp, and ~1/2 tsp of myke.

The experiment is that in each type's northerm-most row, I added 1 Tbsp alfalfa (in addition to the above amendments).

It will be interesting to see if any difference in the ones that have vs. don't have alfalfa.  Last year (2023) I didn't add any alfalfa to the potatoes, and they did well enough.
