When used as a fertilizer, neem cake powder slowly releases these nutrients into the soil, providing long-term nourishment to the plants.
Soil Improvement:
Neem cake powder has the ability to improve the soil structure and texture. It helps to increase the water-holding capacity of the soil, which is important for plant growth. Neem cake powder also helps to improve the soil’s aeration, which helps to prevent soil compaction. The soil becomes more porous, allowing the roots to penetrate easily, and water and nutrients to flow through the soil. Neem cake powder also helps to reduce soil erosion by binding the soil particles together.

When neem cake powder is added to the soil, it helps to repel pests like nematodes, whiteflies, aphids, and thrips. The compounds in neem cake powder also act as an insect growth regulator, preventing the pests from completing their life cycle.
Disease Control:
Neem cake powder is also effective in controlling plant diseases. It contains various compounds that have antifungal and antibacterial properties. These compounds help to control diseases like powdery mildew, rust, and leaf spot. Neem cake powder also helps to prevent the spread of soil-borne diseases like Fusarium and Verticillium.

Neem cake powder is added to the soil before planting the crops, and it slowly releases the nutrients into the soil. It also helps to repel pests and control plant diseases.
Horticulture:
Neem cake powder is also used in horticulture for the cultivation of ornamental plants, bonsai, and indoor plants. It helps to improve the soil structure and texture and provides long-term nourishment to the plants. Neem cake powder also helps to repel pests and control plant diseases.
Landscaping:
Neem cake powder is used in landscaping to improve the soil quality and provide nutrients to the plants. It is added to the soil before planting trees, shrubs, and other plants. Neem cake powder helps to increase the water-holding capacity of the soil, which is important in landscaping, where the plants need to withstand periods of drought. It also helps to prevent soil erosion, which is important in sloping areas.
Vermicomposting:
Neem cake powder is also used in vermicomposting, which is the process of composting organic waste with the help of earthworms. Neem cake powder is added to the organic waste, which provides nutrients to the earthworms and helps to improve the quality of the compost. The neem cake powder also helps to repel pests and control plant diseases in the composting process.
How to Use Neem Cake Powder?
Neem cake powder is usually applied to the soil before planting the crops or plants. It can be mixed with the soil or added as a top dressing. The amount of neem cake powder required depends on the soil type, crop, and plant requirements. As a general guideline, neem cake powder can be used at a rate of 100-150 g per square meter of land. It can also be used as a foliar spray by diluting it in water and spraying it on the leaves of the plants.
Precautions:
- Neem cake powder should not be applied in excess, as it can lead to nitrogen toxicity in the soil.
- Neem cake powder should be stored in a cool and dry place to prevent it from getting spoiled.
- Neem cake powder should not be used in hydroponic systems, as it can clog the pipes and filters.
