Calcium Nitrate TC

Description

1. Product Overview

Calcium Nitrate TC (Technical Grade) is a highly soluble, dual-nutrient fertilizer and industrial additive, composed of 15.5% nitrate nitrogen and 26.5% water-soluble calcium oxide (CaO). Its primary industrial use lies in high-efficiency greenhouse fertigation, open-field crop nutrition, and wastewater treatment as a odor control agent. The key value proposition is its unique ability to deliver rapid nitrogen uptake while strengthening plant cell walls through calcium, reducing physiological disorders such as blossom end rot. Strategically, it is indispensable for precision agriculture and environmental compliance, offering growers and industrial buyers a reliable tool to maximize yield quality and minimize nutrient leaching.

2. Key Specifications & Technical Characteristics

• Chemical composition: Calcium nitrate tetrahydrate (Ca(NO₃)₂·4H₂O) – minimum 99.0% purity

• Nutrient content: Total Nitrogen (N) – 15.5% (100% nitrate form); Water-soluble Calcium (Ca) – 19.0% (equivalent to 26.5% CaO)

• Physical form: White, free-flowing granular or prilled

• Particle size: 2–4 mm (90% within range)

• Bulk density: 1.0–1.1 g/cm³

• pH (1% solution): 5.5–7.0

• Water insolubles: ≤ 0.1%

• Heavy metals (As, Pb, Cd): Conforms to EC Fertilizer Regulation 2019/1009 – trace levels only

• Packaging options: 25 kg laminated PP/PE bags; 500 kg and 1,000 kg FIBC bulk bags; customized big bags

• Shelf life: 24 months in unopened, dry storage (≤ 35°C, < 70% RH) – avoid moisture absorption

3. Core Industrial Applications

• Protected cultivation (greenhouses & nurseries): Used in drip irrigation and hydroponic systems. Performs better than urea- or ammonium-based nitrates because it eliminates root zone acidification and ammonia toxicity, ensuring consistent nutrient uptake under high EC conditions.

• High-value open-field crops (tomatoes, peppers, apples, strawberries): Applied as a split foliar or soil dressing to prevent calcium-deficiency disorders. Outperforms gypsum or lime due to 100% water solubility and immediate nitrate-driven calcium translocation.

• Wastewater treatment (municipal & industrial): Functions as a odor suppressant by accelerating biological oxidation of hydrogen sulfide in collection systems. More efficient than sodium nitrate due to additional calcium’s flocculation effect, reducing downstream sludge volume.

• Concrete & construction accelerators (niche but strategic): Used as a non-chloride setting accelerator for cold-weather concreting. Advantage: No corrosion risk to rebar (unlike calcium chloride).

Efficiency gain: In fertigation trials, calcium nitrate TC reduces nutrient runoff by 30–40% compared to ammonium-based blends, lowering total applied N per hectare.

4. Competitive Advantages

• Quality consistency: ISO 22241-2 & REACH compliant; batch-to-batch variability < 1.5% (validated by third-party SGS reports).

• Supply reliability: Dual-sourced raw material (natural mined + synthetic) with 50,000 MT annual contracted capacity; safety stock held across 3 regional hubs (Rotterdam, Houston, Shanghai).

• Logistics capability: In-house fleet for temperature-controlled storage; anti-caking treatment (≤ 1.5% caking index after 6 months).

• Price competitiveness: Volume-based tiered pricing (spot + long-term contracts) with full hedging against nitrate price volatility.

• Sustainability: 100% nitrate nitrogen – reduces N₂O emissions by 60% vs. urea; calcium sourced from low-carbon nitric acid plants (GreenTag certified, Level A).

• Technical support: Free solubility testing, compatibility charts, and fertigation scheduling software access for buyers ≥ 100 MT/year.
