Castor Cake Fertilizer Bulk Supply Gujarat: Specs

What is Castor Cake (Organic Fertilizer)?

Castor cake, also designated as castor de-oiled cake or expeller castor meal, is the concentrated organic residue generated during the mechanical crushing of Ricinus communis seeds. When castor beans pass through continuous mechanical screw expellers to extract the triglyceride oil, the fibrous seed hull and protein-rich pulp are consolidated under heavy frictional pressure into solid expeller flakes. This expeller meal represents a foundational organic soil amendment valued across commercial horticulture, plantation agriculture, and organic farming.

Agricultural blenders and commercial farm operators rely on castor cake fertilizer bulk supply Gujarat because it provides a concentrated source of plant-derived organic nitrogen. Unlike synthetic chemical fertilizers that dissolve rapidly and leach into groundwater, castor cake decomposes gradually in the soil profile, releasing nutrients through biological activity over an extended growing cycle. Furthermore, the high organic matter content improves soil physical structure, enhances water retention capacity in sandy soils, and stimulates beneficial biological activity. Nagdev Products manufactures high-grade expeller castor cake at our dedicated facility in Deodar, North Gujarat.

How Nagdev Produces Castor Cake at Our Deodar Facility

Nagdev Products produces expeller castor cake at our agricultural processing complex located at Survey No. 301 P-2, Jada-Kotarwada Road, Village Sardarpura, Taluka Deodar, District Vav-Tharad, Gujarat 385330. Our operations feature a 50 TPD seed crushing capacity based strictly on mechanical pressing principles:

1. Seed Cleaning and Screening: Whole castor seeds sourced from North Gujarat agricultural mandis undergo rigorous screening through rotary sieves, air aspirators, and de-stoners to remove soil, sand, stones, and foreign vegetable matter.
2. Mechanical Screw Pressing: Cleaned seeds feed continuously into heavy-duty mechanical expellers. High mechanical pressure extracts the raw oil, while the remaining solid seed mass is extruded through discharge cones as dense, hot expeller flakes.
3. Cooling and Aeration: The freshly expelled cake passes through cooling conveyors and aeration bins to dissipate frictional heat and stabilize residual moisture, preventing spontaneous heating during storage.
4. Grading and Milling: Depending on buyer requirements, the cooled flakes are either retained as natural expeller flakes or transferred to hammer mills to grind into uniform de-oiled organic fertilizer meal (high protein castor meal is under development).
5. Bagging and Quality Control: The finished product is packed into 50 kg laminated HDPE woven bags or 1 MT bulk jumbo bags, with laboratory technicians verifying nitrogen, moisture, and seed oil concentration prior to lot release.

Castor Cake Fertilizer Bulk Supply Gujarat: Plant Sourcing

Procuring castor cake fertilizer bulk supply Gujarat directly from our manufacturing base in North Gujarat provides significant agricultural supply chain advantages. North Gujarat—encompassing the districts of Banaskantha, Vav-Tharad, and Patan—is recognized as the primary castor seed producing belt in India. Operating directly within North Gujarat's castor belt (Banaskantha and Vav-Tharad region) gives Nagdev Products an uninterrupted supply of raw castor seeds, allowing continuous crushing operations and steady seasonal availability of freshly processed castor cake. Sourcing fertilizer directly from our primary crushing mill ensures competitive mill-gate pricing and documented freedom from inert adulterants. Commercial farming cooperatives rely on our castor cake fertilizer bulk supply Gujarat for dependable crop cycles.

From our Deodar facility, established transport corridors support prompt domestic and regional distribution:

• Gujarat Agricultural Markets: Direct dispatch to major farming and plantation belts across Gujarat, including Saurashtra, Kutch, and central agricultural districts.
• Interstate Farm Supply: Road transport provides dependable bulk deliveries to agricultural blenders, fertilizer cooperatives, and plantation estates in Maharashtra, Madhya Pradesh, Rajasthan, and southern India.
• Export Logistics via Gujarat Seaports: Export enquiries welcome. Our proximity to Kandla (Deendayal Port) and Mundra Port facilitates straightforward containerized shipping of palletized 50 kg bags or 1 MT jumbo bags for overseas organic agriculture markets.

Specification Parameters & Soil Nutrition Analysis

Procurement managers and fertilizer granulators evaluate castor cake against established chemical parameters documented on the Certificate of Analysis:

• Organic Nitrogen (N): Specified at 4.5% to 5.5%. Nitrogen is the primary driver of vegetative plant growth and chlorophyll synthesis. In castor cake, nitrogen is bound in organic protein complexes, providing a slow-release nutrient curve that feeds crops steadily over 60 to 90 days.
• Phosphorus (as P2O5): Measured between 1.0% and 1.5%. Organic phosphorus supports early root development, flowering, and energy transfer within plant tissues.
• Potassium (as K2O): Maintained between 1.0% and 1.5%. Potassium enhances plant cellular turgor, soil structure support, and fruit/grain quality.
• Organic Matter Content: Ranges from 75% to 85%. This massive carbon input provides vital organic substrate for indigenous soil microorganisms, improving soil humus formation and cation exchange capacity (CEC).
• Residual seed oil concentration: Typically between 6.0% and 8.0%. Residual triglycerides in mechanical expeller cake provide energy for soil biological digestion while confirming that no chemical solvents were used in extraction.
• Moisture Content: Maintained below 10.0% maximum. Controlled moisture maintains dry meal physical flowability growth during warehouse storage.

Agricultural Applications of Castor Cake Fertilizer

Expeller castor cake serves as an organic fertilizer across diverse farming sectors:

1. Basal Soil Application for Field Crops

Castor cake is broadly applied as a basal dressing prior to sowing field crops like cotton, groundnut, cumin, mustard, and sugarcane. Incorporating 300 to 500 kg per hectare into the soil provides balanced NPK nutrition during initial vegetative establishment.

2. Horticultural and Commercial Fruit Orchards

Growers of pomegranates, mangoes, citrus, and banana plantations utilize castor cake around the root zones of mature trees. The steady nitrogen release matches the seasonal nutrient uptake of fruit trees without inducing vegetative leaf burning.

3. Greenhouse Vegetables and Floriculture

In commercial polyhouse cultivation of roses, capsicum, tomatoes, and cucumbers, castor cake provides high organic matter that improves potting media structure, aeration, and moisture holding capacity.

4. Organic Fertilizer Granulation and Blending

Fertilizer manufacturers use ground castor cake meal as an organic carrier base, compounding it with rock phosphate, neem cake, and potassium humate to formulate customized organic NPK fertilizer granules.

Packaging Configurations and Handling Guidelines

Nagdev Products packages castor cake under dry conditions to preserve nutrient potency and prevent moisture re-absorption:

• 50 kg Woven HDPE Bags: Sturdy, multi-layer laminated polypropylene bags that prevent tear damage and resist ambient atmospheric moisture during handling.
• 1,000 kg (1 MT) Bulk Jumbo Bags: Heavy-duty polypropylene FIBC bags equipped with lifting loops and bottom discharge spouts, optimal for mechanized commercial farms and fertilizer blending plants.
• Bulk Truckload Dispatches: Direct loading of loose expeller flakes or bagged cargo into covered 10-wheeler and 12-wheeler trucks for domestic delivery.

Every commercial shipment is accompanied by a manufacturer Certificate of Analysis (COA) confirming nitrogen, phosphorus, potassium, organic matter, and moisture limits. Storage should be maintained in dry, well-ventilated covered warehouses away from direct moisture.
