Castor De Oiled Cake (Castor Meal)

The Premier Organic Solution for Sustainable Soil Enrichment and Integrated Crop Protection.

Castor De-Oiled Cake is a high-grade organic residue obtained from the solvent extraction of castor seeds. Functioning as a slow-release fertilizer, it provides a steady supply of NPK and essential micronutrients, actively enhancing soil humus and long-term fertility.

Uniquely, it doubles as a natural bio-control agent. Its inherent ricin content effectively protects root systems against nematodes, termites, and white ants, offering a sustainable, dual-action alternative to synthetic chemical inputs.

Castor De-Oiled Cake contains toxic compounds (Ricin) and is strictly for agricultural use as fertilizer; it must never be used as animal feed or fodder.

Key Specifications:
Nitrogen (N): 4.5% – 5.0% | Phosphorus (P₂O₅): ~1.0% | Potassium (K₂O): ~1.0%

Moisture: < 10% | Organic Matter: ~75%
