seed meal

 Castor seed meal is a by-product of the castor oil extraction process. It is made by grinding the castor seeds that remain after the oil has been extracted. Castor seed meal is a high-protein, high-fibre ingredient that is commonly used as a fertilizer for crops. Castor seed meal is a good source of nitrogen, phosphorus, and potassium, as well as other essential nutrients. It is often used as an organic alternative to chemical fertilizers because it is slow-release and helps improve soil fertility over time. However, it should be noted that castor seed meal contains ricin, a toxic compound that can be harmful to both humans and animals, so it should be used with caution and according to recommended guidelines
