Even if the effects were only one-sixth as great, added magnesium is worth a serious look by potato growers in other areas. Ray Hoyum, vice president of market development and communications, IMC Global, agrees that proper plant nutrition is key to high yielding, high quality potatoes. K-Mag provides the proper balance of these needed nutrients to produce a desired crop. Plus, since K-Mag contains both potassium and sulfur, growers may be able to reduce the amount of these nutrients from other sources in the overall mix, further reducing costs. And it does not change the soil pH, even at high application rates.
Higher yields remove even more nutrients.
Therefore, it s essential for potato growers to replenish the soil using a balanced fertility program that pays close attention to magnesium.
