Calcium Nitrate is a high-grade chemical source supplying essential plant nutrients. The standard NPK ratio of this fertilizer is 15.5-0-0, which signifies that it contains 15.5% Nitrogen (N), 0% Phosphorus as P₂O₅, and 0% Potassium as K₂O by total product weight. Under agronomic standards, the phosphorus and potassium components are expressed in their oxide forms rather than elemental phosphorus and potassium.
When dissolved in water, this fertilizer dissociates into plant-available ionic nutrients. This allows roots to absorb them instantly via active transport. Understanding the exact composition prevents chemical lockouts and guarantees optimal nutrient concentrations.
This fertilizer is highly effective when applied to crops and systems requiring quick, specific nutrient supply:
At a standard temperature of 20°C, the maximum solubility limit of Calcium Nitrate is 1200 grams per liter of water. Attempting to mix at concentrations above this threshold will result in precipitation, leaving undissolved particles at the bottom of your reservoir or mixing tank.
To prevent chemical reactions that render nutrients unavailable to plants, observe the following compatibility constraints:
CRITICAL: Never mix Calcium Nitrate with Sulfates (like Magnesium Sulfate or Potassium Sulfate) in a concentrated stock tank to prevent Gypsum precipitation.
Do not mix with concentrated Phosphate solutions (like MAP or DAP) in the same stock tank.
Compare or blend Calcium Nitrate with other high-grade fertilizer materials to complete your custom recipe:
Applying 15.5% Nitrogen via surface broadcast yields a ~30% volatilization loss (4.65% N lost to atmosphere).
