Established in 1992 by Brenton Wilhelm and Janet Coburn, both directors have comprehensive experience in the agricultural and manufacturing sectors.

We understand the vagaries of agriculture, the unpredictability of weather systems and the needs of Australian farmers.

We are unbending in our commitment to quality, yet flexible in our approach to markets, partners and opportunities.

Wilchem takes your crop as seriously as you do 

Our future depends on your success. Products are manufactured from the highest quality feedstocks, sourced internationally and locally, and they work – season after season, year after year.

Wilchem specialises in formulating and manufacturing micro-nutrients for all broadacre cropping applications


Wilchem currently specialises in four micro-nutrient groups: Manganese Sulfate, Zinc Sulfate, Copper Sulfate and Ammonium Sulfate. These are all designed for broadacre cropping situations, and are manufactured at our modern, purpose built manufacturing plant.


Wilchem introduces to the broadacre cropping market a range of scientifically formulated Amino Acid Chelates. This range of products enhances yield & quality, increases the efficiency of trace element uptake within the plant and is very compatible with a large range of crop protection chemicals. These attributes, coupled with protein forming Amino Acids, will compliment most broadacre cropping programs.
