At home I have blocks 25x25ft 2 wide 11 long. I also have single row a6ft apart.
At camp I have them scattered like yours.
Liming with bag spreaders is not fun. I have a tow behnd gandy 3ft drop spreader which works great for rows. Broadcast spreaders make alot of dust, even with pelletized lime. I'd really like a walk behind drop spreader with larger tires.
You should lime a few trees and see what happens.
