Neem oil cake:
Neem cake is the by-product of oil extraction process. Neem cake has adequate quantity of water soluble organic nitrogen. It is a natural fertilizer and pesticide, preferred in organic farming. It helps in controlling nematodes and holds nitrogen in soil for long duration, inhibiting nitrification process. It absorbs and retains water in the soil, thereby removes alkalinity of the soil and improves soil fertility. Apart from nitrogen, phosphorous and potassium, it contains many micro-nutrients such as calcium, sulphur, zinc, copper, iron, magnesium.
