Neem Cake

Neem cake is a byproduct obtained during the extraction of oil from neem seeds. It is a popular organic fertilizer and soil conditioner used in agriculture. Here's some information about neem cake:

1. **Source**: Neem cake is derived from the seeds of the neem tree (Azadirachta indica), a native plant to the Indian subcontinent. Neem seeds contain various compounds with pesticidal and fertilizer properties.

2. **Processing**: Neem seeds are crushed to extract oil. After oil extraction, the leftover residue is dried and ground into a coarse powder, which is known as neem cake.

3. **Composition**: Neem cake is rich in organic matter and contains several beneficial compounds such as nitrogen, phosphorus, potassium, azadirachtin, nimbine, nimbidin, and nimbin. These compounds have insecticidal, nematicidal, fungicidal, and fertilizer properties.

4. **Benefits**:
   - **Fertilizer**: Neem cake acts as a slow-release fertilizer, providing nutrients to plants over an extended period.
   - **Pest Control**: It contains natural compounds like azadirachtin, which repel and disrupt the growth of pests such as nematodes, aphids, whiteflies, and caterpillars.
   - **Soil Conditioning**: Neem cake improves soil structure, water retention, and microbial activity, leading to healthier soil and better plant growth.
   - **Disease Suppression**: It also helps in suppressing soil-borne pathogens and diseases, reducing the risk of crop damage.
   - **Environmentally Friendly**: Neem cake is an organic and eco-friendly alternative to synthetic fertilizers and pesticides, promoting sustainable agriculture practices.

5. **Application**: Neem cake can be applied to soil by mixing it into the top layer or by incorporating it during soil preparation. It can also be used as a foliar spray by mixing it with water.
