Solu-Cal Enhanced Calcitic Lime is the premier brand of calcium-enriched lime for quick and efficient soil adjustment. Solu-Cal works rapidly to adjust soil pH in as little as 6 to 8 weeks. The use of patented PHCA Organic Humic/Fulvic Acid Technology in Solu-Cal significantly increases the availability of applied and stored nutrients in the soil. Proven to be 75% more effective than traditional pelleted lime, one 50-pound bag of Solu-Cal Enhanced Calcitic Lime is equally as effective as four 50-pound bags of standard lime. In addition, Solu-Cal Enhanced Calcitic Lime is treated with a coating that results in significantly less dust during application than untreated pelletized products. The new OMRI® Listing for Solu-Cal ensures that organic growers can now choose a superior Calcitic lime product for turf and agricultural applications.
