What it is / When to use

Zinc source for soil and fertilizer-blend routes

Zinc Sulphate is an economical zinc raw material supplied as monohydrate (ZnSO4·H2O, CAS 7446-19-7, Zn 33-35%) or heptahydrate (ZnSO4·7H2O, CAS 7446-20-0, Zn 21%), 98%, as white powder or 2-4 mm granular. It fits soil application, dry blending, and zinc-containing crop nutrition programs where a sulphate raw material is specified.

  • What it is Zinc sulphate monohydrate / zinc sulphate heptahydrate, 98%, white powder or 2-4 mm granular.
  • When to use Use it when the target route is soil or fertilizer blending, and compare EDTA-Zn for soluble foliar or drip zinc programs.
  • Honesty note specifications are typical for evaluation; final values are confirmed per batch COA.

Applications

Where Zinc Sulphate fits

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

Soil zinc

A practical zinc source for soil-applied programs and broad fertilizer blending.

Monohydrate grade

ZnSO4·H2O is listed with Zn 33-35% and CAS 7446-19-7.

Heptahydrate grade

ZnSO4·7H2O is listed with Zn 21% and CAS 7446-20-0.

Powder or granular

White powder and 2-4 mm granular forms can be discussed by buyer route.

Compare with EDTA-Zn

For foliar, drip, hydroponic, and fully soluble chelate routes, compare EDTA-Zn (Zn 15%).

Batch documents

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

Buyer FAQ

Zinc Sulphate questions

What is the difference between zinc sulphate monohydrate and heptahydrate?
The two grades differ in water of crystallisation and zinc concentration. Monohydrate (ZnSO4·H2O, CAS 7446-19-7) carries roughly Zn 33-35% and is more concentrated, while heptahydrate (ZnSO4·7H2O, CAS 7446-20-0, MW 287.54) carries about Zn 21%. Choose by target zinc loading and blend route.
Which form should I use for soil versus foliar zinc programs?
Zinc sulphate suits soil application and dry fertilizer blending where a sulphate raw material is specified. For fully soluble foliar, drip, or hydroponic zinc programs, compare RunziChem EDTA-Zn (EDTA-Zn-15, Zn 15%), which stays chelated and stable across a wider pH range than a straight sulphate.
What particle sizes and granular grades of zinc sulphate are available?
Zinc sulphate is offered as standard powder, 200-500 mesh micro-powder for faster dissolution, and granular grades including 21% and 33% granular zinc. The exact form, mesh, and granule grade are confirmed against your blending or application route before order.
Are the zinc and purity values guaranteed?
No. Website figures such as the Zn 33-35% and Zn 21% percentages are typical or representative for buyer screening. The current batch certificate of analysis (COA) confirms the final assay, zinc content, appearance, and quality values for the lot you receive.
