Question arose as to whether it is best to fertilize in Fall or Spring.
Have some old unused bags of fertilizer, so will the nitrogen,
phosphorus potassium keep over winter or does their value dimish with
time sitting in the bag?

I remember some farm report saying that unused fertilizer in the ground,
if not used one season will carryover into the next season, but was that
with all three of those fertilizer components?
