The JT Johnson & Sons story began in 1923 when company founder John Theodore Johnson established a small chaff mill plant in Stockport, South Australia.

In 1957 he re-located the plant to nearby Kapunda in the heart of one of the finest hay growing areas in Australia. With the aid of sons Max and Clyde, the business grew rapidly over the next twenty years and in 1976 the company built and commissioned it¹s first Pellet Production Mill.

The success of this operation led to the company making a major investment in 1985 by establishing a new and unique High Fibre Pellet Mill which was regarded to be one of the best in the world. In 2001 the company again invested in technology upgrades to the Pellet Mill. Completed in late 2002, the upgrade has allowed JT Johnson & Sons to formulate specific rations to suit customer demands.

In 1987 the company diversified slightly as it entered the Export Hay markets in Japan, South East Asia and the Middle East. Strict quality control guide lines and the ability to move with demands from the Market has seen continued growth over the past 20 years.

In 1995 JT Johnson & Sons entered in to a joint venture agreement with Japanese company Asahi Industries to form Johnson Asahi. The company has a hay processing plant in Horsham, Victoria that produces oaten hay, alfalfa hay and straw.
