The comment: "If you do  not have worms in your soil, you  have nematodes" really stuck with me.
Solution: add lots of organic  matter.
An old  plastic gallon juice pitcher, next to the kitchen sink, holds my kitchen liquids that contain  anything plants might find  beneficial. This includes liquids from canned  goods, drained pasta water,  rinsed out  cans/bottles of mustard,  tomato paste, and the like all get poured into the pitcher.
A  small, white paint bucket with lid next to the pitcher, serves to store scraps of  fruits and  vegetables until they make it out to the garden. 
A note about store bought compost.  Don't be tricked (I was) by the bags of $1.25   compost at Wal-mart, Lowes, and Home Depot. It is burnt sand with no  nutrients. See a prior post about Lee County Compost.
