I read somewhere that phosphorus absorbs into the soil slowly and should be applied well before planting. Should I just put the phosphorus down when I do the lime? And then apply the potassium after the plants start growing?

If so, is SuperPhosphate any good? That seems to be all my feed/seed store can get. I'm pretty sure it's 0-18-0 and comes in 4 pound bags.

What would be a good potassium fertilizer to use?



Edit: Maybe this will help. My soil analysis says to apply 100lbs of P (Phosphorus)and 100lbs of K(Potassium)per acre. I'm planting about 1/4 acre. What would be my best fertilizer strategy?
