OMAHA (DTN) -- Average retail fertilizer price moves continued to be mixed the third week of September 2020, according to retailers surveyed by DTN. For the second week in a row, prices for five of the eight major fertilizers were lower, while prices for the remaining three nutrients were higher.
Once again, no fertilizer price was up or down a significant amount, which DTN designates as 5% or more.
The five fertilizers that were slightly lower in price were potash with an average price of $344 per ton, 10-34-0 $455/ton, anhydrous $431/ton, UAN28 $219/ton and UAN32 $253/ton.
The three fertilizers that had slightly higher prices included DAP with an average price of $434/ton, MAP $448/ton and urea $360/ton.
On a price per pound of nitrogen basis, the average urea price was at $0.39/lb.N, anhydrous $0.26/lb.N, UAN28 $0.39/lb.N and UAN32 $0.39/lb.N.
While DTN doesn't track micronutrient prices, these fertilizers, which are found in lesser amounts, can still affect crop yield. Therefore, producers have increased applications of these nutrients in recent years. In a recent post in the University of Minnesota Extension Minnesota Crop News titled "Is boron deficiency a problem in Minnesota?" author Dan Kaiser, University of Minnesota Extension soil fertility specialist, looks at how boron levels affect yields.
Kaiser wrote that, based on tissue sampling results, some say boron fertilizer is needed to maximize yields for some Minnesota crops. This, however, may not be true, as widespread boron issues do not appear across most of the Corn Belt.
In a three-year study by University of Minnesota researchers, boron was broadcast at 3 pounds per acre on nine irrigated and nine non-irrigated fields across the state over three growing seasons. Average corn grain yield was the same for strips with or without boron applied.
"Based on the data collected, we could not establish a lower limit to a tissue boron concentration sufficiency range," Kaiser wrote. "It was clear, though, that the need for boron is not as widespread as has been reported in recent years."
Soybeans are highly sensitive to boron toxicity, so applying the micronutrient to beans should generally be avoided, he wrote. Multiple soybean research trials across the state showed yield did not increase at most sites with boron applications, and some locations reported yields actually decreased at a few sites.
"Outside of sandy soils, boron is not likely to be deficient and need fertilizer applied," he wrote. "Be careful if you are thinking about applying boron, as some crops are highly sensitive to boron toxicity."

Retail fertilizer prices continue to be considerably lower in than a year ago. Anhydrous is 15% lower, UAN28 is 14% less expensive, UAN32 is 13% lower, urea is 11% less expensive, both DAP and potash are 10% lower, MAP is 6% less expensive and 10-34-0 is 3% lower from last year at this time.
DTN collects roughly 1,700 retail fertilizer bids from 310 retailer locations weekly. Not all fertilizer prices change each week. Prices are subject to change at any time.
DTN Pro Grains subscribers can find current retail fertilizer price in the DTN Fertilizer Index on the Fertilizer page under Farm Business.
Retail fertilizer charts dating back to 2010 are available in the DTN fertilizer segment. The charts included cost of N/lb., DAP, MAP, potash, urea, 10-34-0, anhydrous, UAN28 and UAN32.
