So you can buy something like ammonium nitrate to hit a plot hard with N. Potash to up the K. Is there a fertilizer that's mostly just phosphorus?

Yep. Got to your co op and ask them for some 0-46-0. There is also am 18-46-0 if you want some nitrogen. These are used to make most blends of fertilizer.

Like marsh said TSP is 0-46-0. DAP is probly gonna be common source tho

This. The dap will be 18-46-0. What exactly you trying to do?

Planting soybeans this summer. Got the soil tests back today. Tested one field that we've planted several years in a row (P = 22 lbs/acre). The other soil test is from a field that I just cleaned up with a chainsaw and hasn't been planted/fertilized in decades (P = 10 lbs/acre). K is decent in both fields and not worried about N since the beans will be inoculated. All that said, just seeing if I can get the P up without paying for N and K, which isn't needed as much.

Most bean fert is a blend of triple(0-46-0) and potash(0-0-60). I'm sure the co op will sell you just the triple. They may have a minimum tonnage they will sell. I know around here they won't deal in small amounts.

I gotcha some N will actually help you some up front Are you going to be getting your fert in bags or bulk? Also what part of the state? Depending on where you are you might be able to get some0-46-0 in bags. But can probably get 18-46-0 in bulk for probably same or not much difference I would go with 18-46-0 all day long if that’s the case

PH is gonna matter too on that newly cleared spot.

Not a lot of triple being used in al but there is some. Lot more dap. Y’all have a lot more in la and up and down the Ms river. Being it’s all imported into Nola now. None produced in the US

I’m hoping to get my TSP bin empty next week for more urea room.

Thanks guys. Yes, we're putting out a little lime this weekend. This is real small scale stuff we're doing and haven't had much luck being able to do anything in bulk (lime or fertilizer). Some places only will deliver 25 tons of lime minimum. They couldn't get to the back to plots anyways. I'm going to Riverside Seed and Feed tomorrow morning and thought I'd try to get a little educated before I start asking if they have any bags. I'm in Tuscaloosa and the farm is in Marion County (not the city of Marion).

Not sure what riverside would have. I do know that the coop in north port, Fayette and Hamilton will have bulk 18-46-0. I’m pretty sure out of one of those they will have some bagged 0-46-0. All those will be on your way depending on where in Marion co you are headed. For lime at one time Hamilton coop had a lime buggy you could rent and get like there But that was a few years ago

Riverside has 50 pound bags of 0-46-0 for $16.50.
