The distinction between Fertilizer and compost is that Compost feeds the soil and fertilizer feeds the plants. Fertilizer adds to the soil's nutrient supply, but instead of feeding the soil food web, the ingredients in fertilizers are intended to meet the needs of fast-growing plants. Fertilizer can be natural or synthetic, whereas compost results from a controlled biological decomposition of organic material.
Compost is sanitized and stabilized product beneficial to plant growth. It contains plant nutrients but is typically not characterized as a fertilizer.
