Fertilizer is used to enrich the growing medium of plants with essential nutrients. It differs from compost in that compost is used as soil or mixed into soil, while fertilizer is added solely as a source of nutrients. Fertilizer can be made with organic waste and enriched with chemicals like Ammonia (for Nitrogen). The purpose of fertilizer is to allow plants to reach essential elements more easily, or to supplement nutrients absent from certain soils.
