Ok I am lost on this one. Like used in this sentence.

Potatoes 4 lbs banded near, but not touching seed potatoes, and 6 lbs at tuber initiation (approximately 50 days later).

I saw one place that said banded might mean dig a trough, then put the fertilizer, then 2 or 3 inches of dirt then seed potato. does this sound right to you guys / gals out there
