Fat Tree, Empty Fruit: The IMO5 Ring at the Drip Line
Cho opens with plans: next time he wants to walk farms and diagnose crops, and he wants Hawaiʻi visitors to eat on natural farms. Then he cuts open the mangosteen a participant gave him. It's nearly empty, because the tree was overfed when young and lacked calcium phosphate the July before. His fix is IMO4 mixed 1:1 with vinegar-moistened bone char, spread in a ring at the drip line ahead of flowering; the room's questions settle what the 1:1 means.
