When assembling a compost pile, there are 2 primary categories of plants, ones that are rich in carbon and ones that are rich in nitrogen
In this lesson we will teach you how to identify nitrogen-rich materials.
Nitrogen is an indispensable element for soil fertility and plant growth.
Nitrogen-rich material is most commonly identified by its green color, but color is not the only criteria.
Kitchen scraps, fruit and vegetable peels, non-edible plant parts, and freshly cut grass are all considered to be nitrogen-rich materials.
In general, they are rich in water and decompose quickly.
Some of these plants have special characteristics which are particularly beneficial for compost.
Nettle, comfrey and alfalfa are rich in nitrogen and contain additional nutrients like calcium, potassium, magnesium or iron.
As they decompose they will bring these important elements to create a balanced and fertile compost. It is therefore advisable to gardeners who practice sustainable food raising to grown them in the garden.
Note that there are several terms for nitrogen rich materials.
They can be called immature, green or nitrogenous material.
