When registering our liquid specialty fertilizer Agrogreen in the USA, the EPA asked us to provide them with information to prove that neem is a fertilizer. Below is the information that we provided EPA - they agreed that neem is a fertilizer!

Neem

The main active ingredient of Neem is Azadirachtin. Neem Cake is an excellent organic fertilizer. Indian farmers have traditionally used deoiled Neem Cake as a fertilizer in their fields. Neem leaves have also been used to enrich the soil, together, they are widely used in India to fertilize cash crops. Farmers in southern parts of India puddle neem leaves into flooded rice fields before the rice seedling are transplanted. Application to the Neem Cake to crops provides them with various nutrients. Neem Cake can also reduce alkalinity in the soil by producing organic acids when mixed with the soil. The calcium and magnesium present in neem cake also aid in removing alkalinity.

Neem for soil fertility and fertilizer management:

Good soil fertility means good crop yields. Preventing the loss of plant nutrients from an eco system is important for soil fertility management. Nitrogen, Phosphorous and Potassium (NPK) are the three major elements that determine soil fertility and should be ideally present in 4:2:1 ratio; Aberrations affect fertility and therefore crop yield.
