i generate good,dark compost from grass cuttings, vegetable matter and shredded paper. is the main value of this compost as top dressing/soil improvement or does it add nutrition?
all of the above
it feeds the soil critters who feed the plants.
Garden compost is all I find I need to feed the garden both veg and flower beds, with the veg plots only every three years, where I put the potatoes, and every other year for the flower beds, also use in a home made mix for planting in pots, for regals and pot mums, with a sixty - thirty mix soil to compost, do give a little boost in pots with year round fertilizer.
