I am building my first vegetable garden. I took some soil to be tested and
it was recommended that I put 8 pounds of 13-13-13 per 1000 sq ft.

My garden is only 160 square feet so I don't need very much. The Coop
suggested a small bag of 6-7-7 and using twice as much (2.5 pounds). This
makes sense, but thought I would check here for confirming advice.
