A blood meal is a valuable organic fertilizer and animal feed ingredient derived from the drying and grinding of animal blood. It is a dark, fine powder rich in nitrogen and other essential nutrients.

A blood meal is widely used as a nitrogen fertilizer in agriculture and gardening. It provides a readily available nitrogen source, a vital nutrient for plant growth and development. The nitrogen in blood meal promotes healthy leaf and stem growth, enhances chlorophyll production, and improves overall plant vigor. It is particularly beneficial for nitrogen-demanding plants like leafy greens, vegetables, and certain fruit crops.
