👑 Castor Cake Fertilizer (Bulk Bag): The Foundation of Sustainable Fertility
- 📈 Superior Nutrient Specification: Guaranteed to meet the highest standards for non-edible de-oiled cake. The bag displays the precise specification of Total Nitrogen, Phosphate, and Potash content, allowing commercial users to calculate nutrient delivery accurately.
- ⏳ Sustained-Release Value: Castor Cake is a master of slow release. In bulk form, it provides an economical, steady stream of balanced N-P-K, drastically reducing the need for frequent, costly re-applications across large areas.
- 🌱 Foundation for Soil Health: Far beyond feeding the plant, Castor Cake actively builds the soil. It rapidly adds stable organic carbon, improving tilth, boosting water retention, and fostering a thriving microbial environment essential for future crops .
- 🛡️ Gentle Root Zone Protection: Contains natural organic compounds that act as a biocontrol agent, helping to deter soil-borne pests and nematodes, providing silent, systemic protection to vulnerable root systems.
- ✅ Large-Scale Certified Quality: Ideal for field crops, large nursery operations, and extensive landscaping. It is the reliable, high-volume organic choice that integrates seamlessly into any sustainable farming practice.

Based on the standard specifications for quality Castor Cake, the minimum guaranteed Total Nitrogen (N) content is typically around 4.0% to 5.0% by weight. (Note: Please confirm the exact minimum from your bag's specification table.)
The product is typically sold as a finely ground meal or powder, which ensures quick incorporation into the soil and aids in the steady breakdown and nutrient release.
Yes. Our Castor Cake is manufactured to high standards (often AS ISO certified) and is suitable for use in certified organic farming systems. We recommend checking with your specific certifying body (like ECOCERT) for approval.
Absolutely. The Castor Cake sold for fertilizer use has been subjected to high heat and steam during the oil extraction and processing, which effectively denatures and inactivates the Ricin toxin. It is safe for application in all agricultural settings.
Application rates vary widely based on soil testing and crop needs. However, a general recommendation ranges from 200 kg to 500 kg per hectare (or 80 kg to 200 kg per acre) applied during initial soil preparation. Consult a soil expert for precise local recommendations.
The slow-release nature provides a continuous, steady nutrient supply, reducing the need for multiple top-dressing applications. This saves labor costs, minimizes nutrient waste through leaching, and ensures sustained plant health.
When stored properly in a cool, dry place away from moisture and direct sunlight, the Castor Cake can maintain its quality for 12 months or longer. Ensure the bag is sealed or stored in airtight containers.
Yes. Castor Cake is fully compatible with most other organic and mineral fertilizers. It is often mixed with Farm Yard Manure (FYM) or compost to enhance the overall nutrient profile of the soil.
It has been proven effective as a natural soil biocontrol. The compounds in the cake help suppress and deter harmful soil nematodes and other soil pests, providing an important protective benefit to cash crops.
By significantly increasing the organic matter content of the soil, Castor Cake improves soil aggregation, leading to better soil structure, reduced runoff, and increased water-holding capacity, which is crucial for efficient irrigation.
