Walmart, America’s largest goods store, recently announced that it bought a share of the agriculture company, Plenty. Plenty specializes in vertical farming. In a statement, Walmart official Charles Redfield said the partnership will help the company offer the “highest-quality foods at the best prices.” Plenty is based in San Francisco, California. Walmart is an international company based in Bentonville, Arkansas. Vertical farmers praise their methods. They say vertical farming grows more food while using less water and land. The method also does not use chemical insect control. It also permits produce to be grown all year near transportation centers, which increases the dependability of supply. Walmart did not comment on the size of its investment or the financial terms of the deal. The company said a Walmart representative will join Plenty’s board of directors when the deal is completed.
