Yes, by using fertilizers and a natural method using the rotation of legumes with other general crops. The nitrogen cycle is the sum of all stages and processes in which nitrogen moves and occurs in the world. We need nitrogen to make proteins in our muscles, blood, deoxyribonucleic acid, skin, hair and nails. Agricultural and industrial nitrogen (N) inputs to the environment currently exceed inputs from natural N fixation. Favorite Answer. When the waste product is released, it contains nitrogen wastes such as amino acids and urea. Check the Terms to Know list at the bottom of the page! As an animal consumes the protein and other material it needs, it then must rid itself of waste material.
