OMAHA (DTN) -- Retail fertilizer prices continue to be mostly lower, according to prices tracked by DTN for the fourth week of February 2020.

Just like last week, five fertilizers were lower in price compared to last month, but none were down a considerable amount. DAP had an average price of $409 per ton, MAP $434/ton, potash $371/ton, 10-34-0 $466/ton and UAN28 $235/ton.

The remaining three fertilizers had a minor price increase, looking back to last month. Urea had an average price of $366/ton, anhydrous $490/ton and UAN32 $277/ton.

On a price per pound of nitrogen basis, the average urea price was at $0.40/lb.N, anhydrous $0.30/lb.N, UAN28 $0.42/lb.N and UAN32 $0.43/lb.N.

With the calendar turning over to March, farmers are finishing up their fertilizer plans for the rapidly approaching spring planting season. For some, their plans started last fall.

Jamin Ringger, a farmer from Gridley, Illinois, was able to apply MAP and lime last fall after the fall harvest in a window of time that was fairly open. In addition, hog manure was also applied.

"We did get a little manure on in the fall and some went on this winter," Ringger told DTN. "We will have to do quite a bit once it dries out in the spring as well."
