Potassium (K) is absorbed by plants in larger amounts than any other mineral nutrient except nitrogen, and is required for nutrient movement in the plant. It is essential for the makeup of over 40 different enzymes and is involved in more than 60 different enzyme systems in plants. Potassium is also important in the formation of sugars and starches in plants. Grapes, in particular, use potassium to improve vine strength and vitality. Potassium is used by plants to regulate the process of opening and closing the stomatal openings of their leaves. at process influences water use efficiency and carbon dioxide use in the plant. Potassium's influence on cell turgor pressure and water relations in the plant helps the plants resist the effects of drought and temperature extremes, and aids resistance to many plant diseases and environmental stresses. e Problem Depending on soil type, 90-98% of total soil potassium is unavailable. Feldspars and micas are clays that contain large amounts of potassium, but plants cannot use the nutrient if it is trapped between the layers of those clays. In persistently dry soils, potassium remains unavailable, as there is no water film surrounding the soil particles. Over time, these minerals break down, and the potassium is released. However, this process is too slow to provide vines the amount of potassium needed for optimal yield and quality. e Opportunity Sure-K has been serving the wine industry for over 20 years. Designed as a full-season potassium source, its application options have been expanding since its inception. Sure-K can be effectively soil applied, through fertigation, or as a foliar. Sure-K provides the same amount of usable K 2 O per gallon as 10-13 units of potash. AgroLiquid's Flavonol Polymer Technology can deliver the potassium in Sure-K to the plant with superior accuracy and efficiency. Sure-K is a clean, chloride- and hydroxide-free potassium solution. is is especially important to grapes, which are sensitive to chloride and salt toxicity. Kalibrate was developed as a full-season liquid potassium source, complimented by AgroLiquid's Flavonol Polymer Technology. With a 2-0-10-6S analysis, a gallon of Kalibrate can provide the same amount of usable K 2 O as 10-13 units of potash in a grower's fertility program. In addition to the potash, Kalibrate also brings the equivalent of two units of sulfur per gallon supplied to help balance the nutrient program for the crop. Kalibrate has excellent application flexibility. Vintners have quickly adopted Kalibrate's research-proven technologies in their wine grape nutrition programs, and have been rewarded with dependable results. Both Sure-K and Kalibrate have unparalleled compatibility with other AgroLiquid products and crop protection products industry-wide. e high efficiency and usability of Sure-K and Kalibrate lead to less total gallons or pounds of K 2 O needed at application times. ese products are industry-leading potassium sources proven through research and trusted by growers.
