Test digs in potatoes are hard to quantify but the grower in eastern Idaho was shocked when his test digs started outperforming all of the untreated fields. As a first time user, the grower used one pint of OII-YS™ on a 40 acre plot in furrow at mark-out with his normal nutrient program. Per grower, the treated yields are expected to return another 20 sacks per acre which will result in a marginal $4,000 profit yield over the untreated field. Photo was taken about 60 days after planting (Summer 2018) and it’s easy to note the significant feeder routes and root mass differences.
