Overview
Copper Sulfate Pentahydrate (CuSO4·5H2O) is a blue crystalline salt widely used as a technical source of copper in agricultural value chains. It is highly soluble in water and can be incorporated into dry or liquid formulations where a defined copper content and a well-known analytical profile are required. The material supplied by Bisley International is intended for industrial use in crop nutrition and related applications.
In agriculture, copper sulfate pentahydrate is used as a copper source in micronutrient fertilizers, foliar sprays, fertigation products and, where permitted by local regulations, in selected animal nutrition premixes and supplements. Copper is an essential trace element for plants and animals, but the actual requirement, permitted dosage and application method are determined by local legislation, species or crop needs and the overall formulation concept. These aspects must be evaluated by the customer's own technical and regulatory teams.
Bisley International focuses on providing consistent technical grade material with controlled assay, moisture and impurity levels, supported by up-to-date technical data sheets, safety data sheets and certificates of analysis. Copper sulfate pentahydrate is classified as hazardous, and appropriate handling, storage and personal protective equipment are required. Customers should always review the latest documentation and comply with local safety, environmental and regulatory requirements before use.
Applications, characteristics and considerations
Applications in fertilizers and nutrition programs
Copper Sulfate Pentahydrate is used as a technical copper source in a range of agricultural formulations, subject to local regulations, registration status and individual customer requirements. Typical applications may include:
- Micronutrient component in solid NPK and multi-nutrient fertilizers designed to correct or prevent copper deficiency in soils.
- Ingredient in foliar sprays and fertigation solutions for fruit, vegetable, cereal and horticultural crops, where copper-based nutrition is part of the overall program.
- Trace mineral source in animal nutrition premixes and supplements, where the use of copper sulfate is permitted and correctly regulated.
Key characteristics
Copper Sulfate Pentahydrate supplied through Bisley International is produced to a defined technical specification suitable for industrial use in agricultural value chains. Typical characteristics include:
- Blue crystalline material with high solubility in water, facilitating liquid and suspension formulations.
- Controlled copper content and assay range, as defined in the applicable technical data sheet.
- Specified limits on moisture, insoluble matter and key impurities to support consistent formulation performance.
- Supplied in industrial packaging formats appropriate for bulk handling and transport.
Handling, safety and selection considerations
Copper Sulfate Pentahydrate is classified as hazardous and must be handled with appropriate care. When selecting and using this material, customers should consider:
- The need for suitable personal protective equipment, ventilation and spill management in line with the safety data sheet (SDS).
- Potential environmental considerations, including copper accumulation in soils and sensitivity of aquatic environments, as defined in local regulations.
- Compatibility with other formulation components, such as phosphates, carbonates or organic chelating agents, to maintain product stability.
