See how much lime to apply in the pond, corrected for the product’s PRNT, for the flooded area.
Pre-sizing and estimating tool: the results do not replace a design, calculation, or report signed by a qualified professional, nor verification against the applicable standards.
Technical responsibility. This calculator is under verification. The reference values and examples are hypothetical, to illustrate the calculation, and are not technical references. The user is responsible for the data entered, the choice of parameters, and the use of the results, and must validate them with a qualified professional before any decision, purchase, application, or construction work.
Corrected amount of limestone for PRNT from 50% to 100%, with the recommended dose; the highlighted bar is your PRNT.
Tonnes of limestone for areas of 0.5 to 5 ha; the dot is your pond.
Drag the controls to simulate data different from what you entered (from 30% less to 30% more) and watch the result change instantly.
Limestone per hectare and in total for the flooded area, for PRNT from 50% to 100%, with the recommended dose entered.

Enter the limestone dose recommended by the analysis (on a PRNT 100% basis), the PRNT of the product you will buy, and the flooded area of the pond. The calculator corrects the dose by PRNT and shows the total in tonnes.
Recommended dose of 2 t/ha, limestone with 80% PRNT, and a flooded 1.5 ha pond.
Corrected limestone = 2 × 100 ÷ 80 = 2.5 t/ha. Total = 2.5 × 1.5 = 3.75 t. Per 100 m² = 25 kg.
Because limestone with a low PRNT reacts less and needs more product for the same effect. The dose is corrected for the PRNT of the product you buy.
From the soil and pond water analysis, with the technical recommendation for the species and region. The dose varies with acidity and alkalinity.
Generally, liming is done with the pond dry or with little water, for better contact with the soil. Confirm the method with the technician.
Yes, as a basis for purchase. Confirm with water and soil analysis, because the dose can vary from one pond to another.
