    In-Season Potassium and Sulfur Fertility in Soybeans

    In a corn-soybean rotation within the Midwest, soybeans can often be overshadowed by the focus on a strong nutrient management program for a corn crop. However, considering the yield potential and genetics in place today, soybean fertility programs need thoughtful consideration as well. We know that when it comes to nitrogen, soybeans are for the...

    How to Boost Cotton Lint Yields with KTS

    Recent research studies conducted in collaboration with Texas A&M University have shown positive results to using KTS® in-season to meet potassium (K) needs of cotton. Application methods evaluated include side-dress coulter applications, side-dress applications through sub-surface drip irrigation and foliar applications. When using KTS in a...

    Blending KTS with UAN

    Mixing any liquid potassium source, including KTS®, with an UAN solution will form potassium nitrate, KNO3. Due to KNO3’s low solubility, precipitation will occur causing the need for water. There is a limited amount of KNO3 that can dissolve in a specific amount of water at any given temperature level. In colder environments, KNO3 is less soluble.

    Necessary Nutrients for Potatoes

    Potatoes need calcium and potassium. Without adequate supply of these nutrients, growers could experience shrink and physiological problems. To ensure good-sized, healthy potatoes from planting through storage, growers should consider two products: KTS® and CaTs® . KTS, potassium thiosulfate, is the highest analysis liquid potassium and sulfur...

    CaTs as a Dual Nutrient Source-Acidifier for Combatting Citrus Greening

    CaTs® (0-0-0-10S-6Ca) is a highly soluble source of calcium and sulfur, produces acid when the sulfur reacts in the soil, and is well suited for application in irrigation water. Because of these properties, CaTs is a valuable tool for combatting citrus greening and achieving improved yields. One of the hallmarks of citrus greening is a degraded...

    Enhancing California Agriculture by Harnessing the Benefits of Thiosulfate Fertilizers

    In March of 1991, the first load of KTS®, potassium thiosulfate, was sold in the state of California. Since that time the product has steadily grown to become a standard potassium fertilizer in California agriculture. The staying power of KTS and its continued consistent growth to this day, is due to several beneficial factors. For one, KTS is a...

    N-Sure & KTS Impacts Your Cotton

    Getting nutrients onto crops at critical times is just half the battle. You must make sure they get into the plant, as well. Finding the right formulation is key, because nutrients interact with each other – sometimes in positive ways for the crop and other times negatively. In cotton, a critical time for potassium (K) is at first bloom and just...
