Greens are materials rich in nitrogen such as leaves, grass, and food scraps. Compost (/ ˈ k ɒ m p ɒ s t / or / ˈ k ɒ m p oʊ s t /) is made by decomposing organic materials into simpler organic and inorganic compounds in a process called composting.This process recycles various organic materials otherwise regarded as waste products. Compost is used to improve the soil fertility in gardens, landscaping, horticulture, urban agriculture and organic farming.
