Calcium Nitrate Tetrahydrate 11.8-0-0 + 23.5CaO
Premium agricultural Calcium Nitrate Tetrahydrate: fully soluble nitrate nitrogen and calcium for fertigation and calcium-nitrogen formulations
Ihumate Calcium Nitrate Tetrahydrate is a high-specification water-soluble calcium nitrogen fertilizer raw material with the formula Ca(NO3)2·4H2O, commonly managed as 11.8-0-0 + 23.5CaO. The product is a white transparent crystal with fast dissolution, supplying nitrate nitrogen and directly available water-soluble calcium for fertigation, hydroponics, sprinklers, foliar calcium programs, water-soluble fertilizers, liquid calcium fertilizers and OEM blends.
1. Nitrate nitrogen plus calcium: nitrate N supports quick uptake, while soluble calcium strengthens cell walls and helps reduce cracking, blossom-end rot, bitter pit, soft fruit and other calcium-deficiency risks.
2. High purity and complete solubility: controlled water-insoluble matter supports clear working solutions, lower emitter-blockage risk and stable use in high-value crops and soilless systems.
3. Formulation friendly: use as the calcium source in A/B fertilizer systems with potassium nitrate, magnesium nitrate and chelated micronutrients. Avoid direct mixing with phosphates and sulfates in concentrated stock solutions.
4. The Ihumate advantage: batch control covers assay, appearance, solubility, insolubles, pH and packaging, supported by COA, SDS, export documents, dependable supply and 1-25 kg OEM/ODM packaging.
Safety and storage: calcium nitrate tetrahydrate is hygroscopic and oxidizing. Store sealed in a cool, dry place away from heat, combustible materials, reducing agents and incompatible products.

Frequently Asked Questions
1
What is the difference between Calcium Nitrate Tetrahydrate and Calcium Ammonium Nitrate?
Calcium Nitrate Tetrahydrate is a high-purity soluble calcium nitrate raw material, typically supplying about 11.8% N and 23.5% CaO. Calcium Ammonium Nitrate is a different granular calcium nitrogen fertilizer often sold as 15.5% N + 26% CaO and includes nitrate and ammonium nitrogen. They should not be treated as interchangeable names.
2
Is it suitable for hydroponics and drip irrigation?
Yes. It dissolves quickly and supplies directly available nitrate nitrogen and calcium, making it suitable as a calcium source in hydroponics, fertigation and A/B stock systems. Formulas must account for Ca, N and EC and be adjusted to irrigation-water quality.
3
Can it be mixed with phosphate or sulfate fertilizers?
It can usually be used in diluted working solutions after validation, but concentrated calcium nitrate stock should not be mixed directly with phosphates or sulfates because calcium salts may precipitate. Use separate A/B tanks and run a jar test.
4
Do the specifications printed in the packaging image apply to this product?
No. Packaging images only show Ihumate bag formats and OEM/ODM capability. Final guaranteed analysis, net weight, label text and regulatory wording follow the contract, batch COA, SDS and destination-market requirements.

Application & Dosage: Calcium Nitrate Tetrahydrate 11.8-0-0 + 23.5CaO
For fertigation, hydroponics, sprinklers, foliar calcium programs and manufacturing of premium water-soluble, liquid calcium, calcium-magnesium and custom NPK fertilizers. Count both nitrate nitrogen and calcium in formulation and manage phosphate/sulfate compatibility in concentrated stock.
Agricultural Application
- Fertigation and Hydroponics:Split nitrate N and calcium from seedling through active growth, flowering, fruit set and sizing, correcting concentration with EC, drainage, soil and tissue analysis.
- Foliar Calcium:Apply low-concentration sprays during young-fruit, sizing and calcium-risk periods. Avoid high heat and intense light; test sensitive crops and new tank mixes first.
Fertilizer Manufacturing
- Water-Soluble and Liquid Fertilizers:Use as a clear calcium source in A/B fertilizers, liquid calcium products and premium WSF with potassium nitrate, magnesium nitrate and chelated micronutrients.
- Compatibility Control:Separate from phosphate and sulfate concentrates. Validate solubility, pH, EC, low-temperature stability and precipitation risk before commercial production.
Application Ratio Scheme
| Crop Name | Growth Stage | Application Ratio |
|---|---|---|
| Fertigation/Sprinklers | Seedling to fruit sizing | 10-30 kg/ha per application; adjust to analysis and crop demand |
| Hydroponics/Soilless | Nutrient-solution preparation | Calculate from target Ca, N and EC; do not use a fixed field rate |
| Foliar Spray | Calcium-deficiency prevention or young fruit | 0.3%-0.8%; conduct a crop-safety test first |
| Fertilizer Production | A/B fertilizers, liquid calcium and WSF | Calculate from target CaO, Ca and N analysis |
