Halbert Broster started his farming career working as hired help for Wabash and Edwards County farmers.  Halbert and Lucille Broster had made it their primary goal to one day purchase some land and create a farming business of their own. In 1948 they had finally saved enough money to make this goal a reality when they purchase land in Keensburg, IL.  In 1960, they expanded their farm by purchasing land in Lick Prairie, IL, where the operations headquarters resides today.

After farming several years, raising hogs became a large focus of their business. Their oldest son, Elbert Broster, farmed with Halbert until going on his own. Their second son Eldon Broster became a school principal in Lincoln IL. Their youngest son, Allen Broster attended Wabash Valley College and worked as an intern at the former Rich-Law Service Company (a farm service company). It was during this time a neighbor approached Allen regarding wanting to sell him 80 acres as well as rent him an additional 350 acres. This opportunity allowed Allen to become a full time farmer with his father, Halbert, in 1975. Allen was married to a farm girl, Debbie Jones, in 1976 and together they lived on the 80 acres he had purchased. They have two children, Brandi and Chad. In the summer of 1978, Halbert and Allen decided to discontinue the hog operation and concentrate fully on row crop production. It was in 1986 that Halbert and Lucille decided to retire and sold their homestead to Allen and Debbie.

Chad Broster attended Wabash Valley College and worked at Wabash Valley Service Company and Peavy grain elevator during his internships. Chad decided farming was in his blood and joined the farm in 1999. Chad married Ashlie Meier in 2002. They now have two children Cole and Audrey. Chad has farmed with his father now for 14 years and is an integral part of Broster Farms. Their daughter, Brandi, married Brad Neale and they have 3 daughters (Mallory, Estella and Brooke) and live in Westfield, IN.

As the years have passed more land has been purchased and rented, which brings Broster Farms current farming acreage to 3800+ acres. Their operation consists of growing corn, soybeans, wheat, milo, and white and yellow corn for human consumption. Broster Farms operates in Wabash and Edwards counties in Southern IL.
