A Partnership with Growers!

At CALAMCO, we are more than just a fertilizer supplier, we are a community of over 900 California growers and dealers working together to strengthen agriculture across our state. Since 1957, our cooperative has been built on the shared values of partnership, trust, and sustainability.

As a grower-owned company, every decision we make is rooted in supporting the people who feed our communities. For generations, our shareholders have benefited from the stability and shared success that come with being part of something bigger, a cooperative that truly works for its members.

Together, we are growing a stronger, more sustainable future for California agriculture.
