A success story that spans 50 Years!
After founding The Best Fertilizers Co. in 1932, Lowell W. Berry had a vision to form California Ammonia Co. (CALAMCO) – a joint venture involving The Best Fertilizers Co. and a group of California farmers. CALAMCO was incorporated in 1957 for the principal purpose of manufacturing and selling anhydrous ammonia to its stockholder-patrons. 1958 marked the construction of the ammonia plant at Lathrop.
- In 1978, financing of an ammonia terminal at the Port of Stockton was approved by CALAMCO’s Board of Directors, and construction of the first tank began.
- By the end of 1981, CALAMCO had expanded to two 20,000 ton storage tanks and had established itself as a major terminal operation, importing ammonia from world-wide sources.
- J.R. Simplot saw the potential of expanding his operation in California agriculture in 1984 by purchasing Occidental (formerly Best Fertilizers Co.) along with their interest in California Ammonia Co., becoming CALAMCO’s industry partner.
- In 2001, CALAMCO built a 40,000 ton capacity UAN32 storage facility at their Stockton terminal, which is operated under a contract with the J.R. Simplot Company, who procures and markets the UAN32 solution. In 2011, a new long-term agreement was reached with the J.R. Simplot Company to develop an additional 30,000 tons of storage, bringing the facility’s storage capacity to 70,000 tons. The increase in storage and load-out infrastructure position CALAMCO and Simplot as a leading UAN32 supplier in California for years to come.
