The soil component that contributes the most nitrogen to plants is humus. Humus is the organic component of soil, formed from the decomposition of plant and animal materials. It is rich in nutrients, including nitrogen, which is essential for plant growth. Clay, sand, and silt have different physical properties and nutrient-holding capacities but do not provide as much nitrogen as humus does.
