fertilizer and lime
 

I have the results from my soil samples back from the lab. Is there a formula or some other way of figuring how much fertilizer and/or lime I need to add?

Maybe this will help.

I apparently don't have all the info I need to fill out that form.

How big is your plot going to be?

Post what they sent you.

Is it something like

N 60-80 units

P2O5 100-120 units

K20 80-100 units

They are all a little different. Tell us what you got and we will try to read it for you.

Here is one I'm doing that needs 1.1 tons of lime per acre and 60 units each of N, P2O5, and K20. 600 lbs of 10-10-10. (60 units/10%(.10)= 600). For 17-17-17 fertilizer 60/.17 or 17% would be 350/lbs acre.

Post the raw soil test numbers, and the crops you are considering. We can figure out a good plan with that information. IF you have the information, please post if pH is 1:1 water or another method. Also, if they list how they extracted the P and K (Mehlich III, Bray, Olsen, etc.) that would provide some more fine tuning of the results.
