What is neem cake?
Neem cake is derived from the seed kernels of the neem tree, which is valued for its dual properties of being a fertilizer and a pest repellent. After the extraction of oil from the neem seeds, the leftover seed cake is processed into granules or powder, which can be used as an organic fertilizer or pesticide. Neem cake fertilizer is well known for its rich nutrient content including NPK (nitrogen, phosphorus, and potassium) as well as other micronutrients like magnesium, calcium, and sulfur, which are essential for better plant growth.
