Wallace became a full-time writer and editor for the family-owned paper, Wallace's Farmer, after he graduated college in 1910.
He was deeply interested in using mathematics and economics in agriculture, and he learned calculus as part of an effort to understand hog prices.
He also wrote an influential article with pioneering statistician George W. Snedecor on computational methods for correlations and regressions After the death of his grandfather in 1916, Wallace became the co-editor of Wallace's Farmer alongside his father.
In 1921, Wallace assumed leadership of the family paper after his father accepted appointment as secretary of agriculture under President Warren G. Harding.
His uncle lost ownership of the paper in 1932 during the Great Depression, and Wallace stopped serving as editor of the paper in 1933.

In 1914, Wallace and his wife purchased a farm near Johnston, Iowa; they initially attempted to combine corn production with dairy farming, but later turned their full attention to corn.
Influenced by Edward Murray East, Wallace focused on the production of hybrid corn, developing a hybrid corn known as Copper Cross.
In 1923, Wallace reached the first ever contract for hybrid seed production when he agreed to grant the Iowa Seed Company the sole right to grow and sell Copper Cross corn.
In 1926, he co-founded the Hi-Bred Corn Company to develop and produce hybrid corn.
Though it initially turned only a small profit, the Hi-Bred Corn Company eventually became a massive financial success.
