Red Potato Study

FRESH MARKET ORGANIC RED POTATOES were grown on a farm field in Moses Lake, WA., where AZOMITE® granular treatments were broadcast pre-plant at two rates of 150 and 300 lbs/acre on April 1, 2017, in four replicates in a randomized complete block design, in 6,000 square-foot plots. All plots had 25 ton/ac of feedlot manure incorporated in the fall as the standard fertilizer for this crop, which provided 90 lb/ac N, 20 lb/ac P, and 105 lb/ac K. The control plots received no AZOMITE®.
