Mix by volume (not weight):
Apply at the rate of 4 to 6 quarts per 100 square feet once per year.
For high-demand vegetables, side dress a few weeks after seedlings have come up. Sprinkle small amounts of fertilizer around each plant, thinly covering the area that the roots will be growing withing the next few weeks. Repeat this process every 4 weeks, placing each dusting farther from the plant's centers. 4 to 6 quarts per 100 square foot can be used each year in this way, but if an increase in growth rate is not noticed, stop adding more because it is not needed.
Add compost to your soil as often as you can. A 1/2" layer added each year is typical.
Use a typical compost bin that creates a high-heat situation and converts the material quickly. Most of nutrient value is lost. A good set of plans for one type is located here.
(from Gardening When It Counts) Build one compost heap a year in early fall. Accumulate all vegetative wastes and kitchen garbage into one big stack and let it dry out throughout the year.

Dick Pierce taught me the following in his class:
If you keep your walkways mulched with 4 to 6" of wood mulch (native tree waste is perfect, and usually available for free from tree trimming companies) you will qutomatically build compost with zero effort. Every 5 years or so, just rake up the remaining wood pieces, sift out your nice compost, and add more wood mulch to the walkways.
