Copper Sulfate Pentahydrate

High-purity agricultural Copper Sulfate Pentahydrate: a consistent copper source for professional fertilizer formulations

Ihumate Copper Sulfate Pentahydrate consists of uniform bright-blue crystals with CuSO4·5H2O > 98% and Cu > 25%. Its strong water solubility makes it suitable as a raw material for copper micronutrient fertilizers, water-soluble fertilizers, compound fertilizers and agricultural formulations authorized under local regulations.

1. Concentrated water-soluble copper: the defined copper analysis supports accurate formulation and correction of copper deficiency confirmed by soil or tissue testing.

2. Uniform crystals and rapid dissolution: controlled particle size supports dosing, blending and dissolution, while low insoluble matter helps maintain clean working solutions.

3. The Ihumate advantage: batch management covers assay, copper, free acid, insoluble matter, pH, appearance and particle size, supported by COA, export documents, reliable supply and OEM/ODM packaging.

Safety and compliance: the margin between copper deficiency and toxicity is narrow. Agricultural rates must follow soil and tissue tests, local agronomic advice and the product label. Fungicide, algaecide or other pesticide use requires registration in the destination market.

Frequently Asked Questions

Ihumate FAQ: Sourcing, organic certification, logistics, and customization.
Apply for Ihumate Free Samples: Global shipping for lab compliance testing.
1

Which agricultural formulations can use Copper Sulfate Pentahydrate?

It can supply copper in micronutrient fertilizers, water-soluble fertilizers, compound fertilizers and professional agricultural formulations. Pesticide or organic-production uses require confirmation of local registration, permitted use and label conditions.
2

How does Copper Sulfate Pentahydrate differ from EDTA Copper?

Copper sulfate offers high copper concentration and strong cost efficiency, but free copper is more likely to become fixed or precipitate in high-pH, hard-water or phosphate-rich systems. EDTA Copper is generally more stable where compatibility and nutrient availability are priorities.
3

Can it be applied directly through foliar spray or fertigation?

Only when copper deficiency is confirmed, the concentration is professionally calculated and local labels allow the use. Excess copper may injure foliage and roots or accumulate in soil, so every new program should begin with compatibility and small-area safety tests.
4

Which materials should not be mixed with concentrated copper sulfate?

Avoid direct concentrated mixing with strong alkalis, lime, carbonates, phosphates and untested high-strength fertilizers because pH changes or precipitation may occur. Complete a jar test before commercial production.
5

Do the specifications printed in the packaging image apply to this product?

No. The image only demonstrates Ihumate packaging formats and OEM/ODM design capability. Final guaranteed analysis, net weight and regulatory text follow the contract, batch COA and destination-market requirements.

Application & Dosage: Copper Sulfate Pentahydrate

For production of copper micronutrient fertilizers, water-soluble fertilizers, compound fertilizers and professional agricultural formulations. Field use is limited to confirmed copper-deficient sites, with rates determined from soil pH, organic matter, crop sensitivity and previous copper inputs. Disease-control or algaecide uses require locally registered products and label rates.

Fertilizer Production

  • Micronutrient Formulation:
    Calculate input from Cu > 25% for copper-containing water-soluble, compound and customized micronutrient fertilizers.
  • Compatibility Management:
    Control stock-solution pH and separate from concentrated phosphates, carbonates and strong alkalis; complete jar and stability tests before scale-up.

Agricultural Application

  • Copper Deficiency Correction:
    Use only after soil or tissue testing confirms deficiency and prioritize crop- and soil-specific recommendations from local agronomists.
  • Risk Control:
    Record cumulative copper input and monitor soil to avoid phytotoxicity, root injury and long-term copper accumulation.
