Record amount of nutrients removed from U.S. soils

United StatesGrowers around the USA should remember they’re removing more than just record yields from their fields this harvest season.
"The predicted highest average corn and soybean yields on record offer many reasons for our industry to celebrate the advancements that have helped us reach this level of production," says Dr. Kyle Freeman, director of New Product Development at The Mosaic Company. "But it‘s also important for growers to remember that with record yield comes record nutrient removal, and necessary measures will need to be taken to replenish those nutrients."
The October crop forecast from the USDA predicts a 15.2-billion-bushel corn crop and a 175.3-bushel-per-acre average. That equates to an estimated 61 pounds of phosphate (P2O5) removed from every acre.
The same forecast predicts a soybean harvest of 4.36 billion bushels, averaging 52.5 bushels/acre, which will remove 63 pounds/acre of potassium oxide (K2O) from U.S. soils.
Mosaic agronomists are advising their retail customers to urge growers to examine nutrient removal rates closely this fall.
"Unfortunately, regardless of how much a crop is worth per bushel, it’s still pulling just as many nutrients from the ground," Dr. Freeman says. "For some, this will be the third straight year of very difficult decisions related to input costs. Those who have cut back on fertilitizer costs may find themselves in a situation that‘s very hard to rebound from if they don‘t adjust their plans to address the effects of this record yield."
To address these nutrient concerns, growers and retailers may consider granular products with years of proven research from The Mosaic Company. Each offers efficient, balanced delivery of key nutrients, so growers can be confident they‘re getting the most out of their fertilizer spend.
Studies show MicroEssentials SZ and S10™ can increase corn yield by 5.4–8.8 bu/ac over MAP and DAP. MicroEssentials SZ is a proprietary fertilizer (12-40-0-10S-1Zn) specially formulated for use on most crops, including corn and wheat. Through Mosaic‘s patented Fusion® technology process, nitrogen (N), phosphorus (P), sulfur (S) and zinc (Zn) are fused into each nutritionally balanced granule, delivering uniform nutrient distribution across the field.
Aspire with Boron is particularly suited for soybeans, alfalfa, corn and cotton because micronutrients such as boron are essential for plant growth. Aspire is the first-of-its-kind micronutrient-enhanced potash fertilizer. Formed using innovative Nutriform technology, Aspire premium potash (0-0-58-0.5B) combines potassium (K) and boron (B) in each granule to help achieve balanced crop nutrition.
