OMAHA (DTN) -- The average retail price of all eight major fertilizers declined again the fourth week of August 2019, with nitrogen fertilizers setting the pace, according to retailers surveyed by DTN.
This marks the third week in a row all prices have been lower.
Half of this week's price declines were significant, which DTN considers a price change of 5% or more compared to the prior month. Of those, the price of both anhydrous and UAN32 were down 9% at $528 per ton and $290 per ton, respectively.
MAP was 7% lower than a month earlier, while UAN28 was down 6% from last month. The phosphorus fertilizer (MAP) had an average price of $494/ton, and UAN28 was $256/ton.
The remaining four fertilizers were lower in price than the same week in August, but the price moves were less significant. DAP had an average price of $491/ton, down $3; potash $387/ton, down $6; urea $412/ton, down $16; and 10-34-0 $470/ton, down $16.
On a price per pound of nitrogen basis, the average urea price was at $0.45/lb.N, anhydrous $0.32/lb.N, UAN28 $0.46/lb.N and UAN32 $0.46/lb.N.
As prices have moved lower in recent weeks, the price of MAP is now lower in price than it was at the same time last year, down 4%.
Seven of the eight major fertilizers continue to be higher compared to last year. DAP is 1% higher, 10-34-0 is 5% more expensive, UAN32 is 7% higher, potash is 8% more expensive, both anhydrous and UAN28 are 10% higher, and urea is 13% more expensive compared to last year.
While nitrogen fertilizer prices have sunk lower in recent weeks, the crop is starting to show nitrogen deficiency symptoms in cornfields across the Midwest.
Crops in the past few weeks have begun to show substantial nitrogen deficiency around the R3-R4 stage, according to a report titled "Late-season nitrogen deficiency in corn: What you need to know" by the University of Minnesota Extension in the Minnesota Crop News segment.
Brad Carlson, University of Minnesota Extension educator, wrote that the challenging conditions seen during planting led to less-than-ideal seedbeds, with compacted areas in many fields affecting rooting and a lot of early season moisture that may have prevented deep rooting and potentially led to denitrification.
In addition, a widespread issue this year is compaction caused by manure application when fields were too wet.
"Given this year's circumstances, there are many situations where the need has surpassed the supply," Carlson wrote. "When these conditions develop this late in the season, it is too late to correct the problem."
Research has shown that it is too late in the season to add nitrogen to increase yield, and the soil will continue to mineralize N as long as there are warm temperatures and adequate soil moisture.
If you are concerned about the nitrogen status of your crop, you can use the basal stalk nitrate test. While this test will not tell you what the right amount of nitrogen fertilizer should have been, it will tell you whether the crop had adequate, deficient or excessive amount of nitrogen, according to the report.
