"With our SuperCal 98G advanced engineered lime, growers can see soil pH improvement in weeks instead of years," says Hoiberg. There is an option to help growers increase soil pH and protect yields. Heading into spring planting season, ag lime application ceases as dealers transition into fertilizer applications. Growers should take a proactive approach to managing pH, as they do all other inputs for maximum yields." No other farm input is treated in this way. If conditions are not optimal for an application of ag lime, they usually wait until the next year. Generally speaking, growers may decide to apply lime every three to five years. "Growers have many inputs to balance, and pH is one issue that's often pushed to the back burner.

"Ignoring one of the most important agronomic factors like pH correction will cause yields to suffer," says Hoiberg. Managing soil pH on a yearly basis is the most effective way to maintain optimal soil pH. As soil acidity is lowered, corrective measures to bring soils back to optimal conditions for crops are harder to achieve. Soil pH of 5.7 can cost a grower an additional $200 per acre of income at today's prices, even more if the pH is lower.Ī University of Wisconsin study cites low pH as reducing yield up to 40%. Cool fall soil temperatures caused many growers and dealers to choose anhydrous application over limestone application."Īccording to Hoiberg, applying more nitrogen fertilizer (the main source for acidity) and skipping limestone application is a recipe for lower yields. These are just a few complications from an unusual 2013 weather year that started with an extremely wet and late spring and ended with a late harvest.

"In many locations, snow prevents lime applications. Andrew Hoiberg, Director of Research and Development at Calcium Products. "This time of year, limestone quarries are either out of limestone or have frozen piles of ag lime which can't be accessed until the spring thaw," says Dr. Unlike standard ag lime, advanced soil amendment products such as SuperCal 98G provide fast and complete soil pH changes because of they contain extremely small lime particles (150 microns versus 590 microns for standard ag lime.) Engineered to have high reactivity, the products change soil pH within weeks and maintains soil pH changes in subsequent years. CALCIUM PRODUCTS: THERE'S STILL TIME TO APPLY LIMEįor growers unable to apply lime last fall, a new generation of engineered lime products are a solution that can be applied year-round.
