Best bulk NPK brands?

Hello again,

My buddies are starting a farm in Florida and asked for some help researching soil ammendments for their fields. They have some ideas but figured I would reach out to the pros here to see what bulk recommendations you could make on good sources of, N, P & K. Also looking for some agriculture lime, but i think they have that sourced already. Any recommendations? Thx


I’m not sure if it’s what you’re looking for but @idacal has a great soil amendment. :nerd_face:


Perhaps these folks is what you are looking for:

Unto my second year with these folks, using as an additive to my normal feeding.
