You have to be more specific.

do you use compost for fertilization, mulching, or soil conditioning?

do you add nitrogen fertilizer?

The main reason is for soil conditioning.
I will continue to mulch with newspaper/grass clippings since I don't have enough compost.
I do also add synthetic fertilizer, either N or a complete fertilizer depending on the plant, but would like to minimize as much as possible.
Thanks

You can condition the soil with leaves used as mulch, as well. I usually add the bulk of them around June 15, under plants that have already grown.

This said, I prefer to use unfinished compost under tomatoes, potatoes and squash. Since I do not have much myself, I add a lot of leaves to it. It will finish there during the season and be nice soil for lettuce, carrots, or onions next year. Asparagus, IMHO, just needs mulch and time.

Brassica and chard/beets should have lowest priority since they do not form mychorrizal alliances. They just need straight fertilizer and decent, but not great, garden soil.
Carrots, parsnip, beans and peas make it in soil that is less fertile, so they, too, should be at the bottom of the heap.
