* Available phosphorus: the fraction of phosphorus the animal can actually digest and utilise, determined in the laboratory by its solubility in 2% citric acid (EU method). The product is not water-soluble and is intended for inclusion in dry feeds.
Applications
- Poultry feeds (broilers and layers)
- Cattle, sheep and calf feeds
- Fish feeds and mineral mixtures
- Premixes and mineral lick blocks
Packaging & Storage
- Lined polypropylene bags of 25 / 50 kg or 1-tonne jumbo bags
- Store in a dry, well-ventilated place away from moisture
- Shelf life: 24 months in the original sealed packaging
Notes for buyers
What is the phosphorus percentage of DCP?
Pure dicalcium phosphate dihydrate (CaHPO₄·2H₂O, molar mass ≈ 172.1 g/mol) contains 18.0% P and 23.3% Ca, calculated from the IUPAC standard atomic weights; the anhydrous form (CaHPO₄, ≈ 136.1 g/mol) contains 22.8% P. That is why feed-grade dihydrate DCP is traded as “DCP 18%”. This sheet guarantees total P ≥ 18.0%, of which ≥ 16.2% is available (soluble in 2% citric acid); the certificate of analysis gives the actual result for each batch.
How much DCP supplies 1 kg of phosphorus?
From the guaranteed minimums: 1 / 0.162 ≈ 6.2 kg DCP per kg of available P (1 / 0.18 ≈ 5.6 kg on total P), bringing about 1.3 – 1.5 kg of calcium with it. When comparing offers, divide the price by the available-P content rather than comparing price per tonne.
Safety: Not classified as hazardous under GHS. Wearing a dust mask and safety goggles during handling is recommended to avoid inhaling dust. A Safety Data Sheet (SDS) and a Certificate of Analysis (COA) for every batch are available on request.
