The ins and outs of potato storage

In potatoes, the factors that affect storage performance include environment, your agronomy, varietal traits, disease, and harvest and management practices.Post-harvest potato storage expert Todd Forbush of Techmark Inc. in Lansing, Mich., says quality potato storage requires just two things: quality storage facilities and quality potatoes to store. “Neither will meet their potential without both working successfully together,” he says. The first step is to evaluate your existing facility to decide if it needs just an upgrade or something different entirely. When evaluating an existing structure, you need to look at its location, the structure itself, its insulation system, its ventilation systems and the controls. “Why is it that we have a ventilation system in potato storage?” Forbush asks. Because you want to create a uniform environment, while at the same time maintaining proper potato temperature. You also want to provide oxygen for respiration and remove carbon dioxide from respiration. The second part of the quality potato storage equation is the potato itself. In potatoes, the factors that affect storage performance include environment, your agronomy, varietal traits, disease and harvest and management practices. The most important factor in determining storage performance is variety. More
