Organic crop growers now have a pure, consistent and reliable potassium fertilizer option with the release of Protassium+ Organic sulfate of potash from Compass Minerals. Protassium+ Organic is a dual-nutrient, concentrated sulfate of potash (SOP) offering high potassium (50 percent potassium) and plant-available sulfate sulfur. It is the only domestically produced and packaged SOP certified and approved for organic food production by the Organic Materials Review Institute (OMRI), California Department of Food and Agriculture (CDFA) and USDA National Organic Standards Board (NOSB).
Compared with other organic fertilizer options, like manure, Protassium+ Organic allows growers to reduce the amount of applied fertilizer – i.e., it requires three tons of manure to apply the same amount of potassium in only 0.18 ton of Protassium+ Organic – minimizing time, labor and fuel expenses. Additionally, compared with manure or compost, Protassium+ Organic offers a safe, reliable and consistent potassium nutrient source that is easy to handle, blend and apply.
“Organic food production is increasing each year. To help meet this demand, our customers are asking for a safe, reliable and high-quality organic potassium nutrient product for their crops,” says Todd Denzin, vice president of sales and marketing for Protassium+. “From the moment Protassium+ is drawn from the Great Salt Lake, it is in its purest organic form. We do our best to preserve that integrity until it arrives to our growers’ fields.”
Although not widely known throughout the organic production community, SOP (K2SO4) offers both conventional and organic growers numerous performance advantages not found in any other potassium source produced in North America. Containing 50 percent potassium, SOP fertilizer – such as Protassium+, helps supports plant resistance to drought, frost, disease, and pests, among other growing stressors. With less than 1 percent chloride, Protassium+ has the lowest salt index of all major potassium sources – minimizing risk of toxicity and soil salinity levels – an important consideration, even more so in drought conditions or when irrigation groundwater quality is a concern.
