What it is / When to use

Chelated calcium for foliar and fertigation programs

EDTA-Ca-10 is a fully water-soluble EDTA calcium disodium chelate (C10H12N2O8CaNa2·2H2O, CAS 62-33-9) supplying Ca 10% with pH 6-7.5. Because the calcium stays chelated across a wide pH range, RunziChem exports it as a stable calcium source for foliar, drip fertigation, and soil programs on fruit trees and field crops.

  • What it is EDTA calcium disodium salt, white water-soluble powder, Ca 10%, CAS 62-33-9.
  • When to use Use it for foliar, drip, and hydroponic calcium programs that need a stable chelate; compare Calcium Ammonium Nitrate (CAN) for lower-cost soil and blend calcium.
  • Honesty note specifications are typical for evaluation; final values are confirmed per batch COA.

Applications

Where EDTA-Ca-10 fits

Confirm crop, rate, compatibility, and local label requirements before application.

Foliar calcium

Fully soluble chelate for rapid calcium uptake by leaves and fruit in foliar sprays.

Drip & fertigation

Compatible with common feeding systems for drip irrigation and fertigation calcium programs.

Wide pH stability

Ca 10% stays chelated across a wide pH range, keeping calcium available where straight salts precipitate.

Deficiency correction

Corrects and prevents calcium disorders such as fruit cracking and blossom-end rot in fruit and vegetables.

Compare with CAN

For lower-cost soil and blend calcium with nitrogen, compare Calcium Ammonium Nitrate (CAN).

Batch documents

TDS, COA, and SDS support procurement and formulation review.

Buyer FAQ

EDTA-Ca-10 questions

When should I use EDTA-Ca-10 instead of calcium ammonium nitrate (CAN)?
EDTA-Ca-10 is a fully water-soluble calcium chelate (Ca 10%, CAS 62-33-9) that keeps calcium available across a wide pH range, so it is preferred for foliar sprays, drip fertigation, and hydroponics where a stable, chelated calcium is needed. Calcium ammonium nitrate (CAN) is a lower-cost inorganic source that also supplies nitrogen and is better suited to soil and blend programs. Choose EDTA-Ca for chelated stability and CAN for bulk nitrogen-plus-calcium supply.
What are the typical specifications of RunziChem EDTA-Ca-10?
RunziChem EDTA-Ca-10 is EDTA calcium disodium salt (C10H12N2O8CaNa2·2H2O, molecular weight 410.3, CAS 62-33-9), supplied as a white water-soluble powder with Ca 10%, pH 6-7.5 in 1% solution, and heavy metals (as Pb) ≤10 mg/kg. These are typical values for buyer evaluation and are confirmed on the batch COA.
How is EDTA-Ca-10 applied in crop nutrition programs?
EDTA-Ca-10 is used to correct and prevent calcium deficiency in fruit trees, vegetables, and field crops. Because it is fully water-soluble, it works in foliar sprays for rapid uptake by leaves and fruit, in drip irrigation and fertigation, as a soil drench, and in soilless or substrate culture. Confirm crop, rate, and tank compatibility before application.
Is the calcium content guaranteed?
No. The figures shown for EDTA-Ca-10, such as Ca 10% and pH 6-7.5, are typical values for buyer screening. The current batch certificate of analysis (COA) confirms the final calcium content, pH, appearance, and heavy-metal values for the lot you receive.
