Blood meal is a dry, powdered form of animal blood, often derived from cattle or pigs. It is primarily used as a high-nitrogen fertilizer in gardening and agriculture, providing essential nutrients to plants. The high protein content also makes it a valuable ingredient in animal feed. In addition to its agricultural uses, blood meal can serve as a natural pest deterrent. When sprinkled around plants, it can help repel certain pests due to its strong odor. This makes it a popular choice among organic gardeners looking for eco-friendly solutions to enhance soil fertility and protect their crops.
