I went to Sothern States and bought several bags of fertilizer. When I
got home I notice it was not exectally what I thought I was getting. The
bag had numbers of 24-4-4 and the 40 lb bag said it covered 8500 sqft.
It did have some weed killer in it that another brand did not have , but
the other bag had the same 24-4-4 in it and covers 15000 sqft. Why
would one cover almost twice the footage as the other ? I could see it
being in the weed killer, but the nitrogen being a high number like 24
seems that it would make that way too much.

The herbicide carrier dilutes the amount of fertilizer per pound of
product.
