OMAHA (DTN) -- Retail fertilizer prices continued their recent upward trend, moving higher again the second week of March 2018, according to retailers surveyed by DTN. Prices for all eight of the major fertilizers were higher compared to last month.
As has been the case in the past couple of weeks, the price of only one fertilizer was up a significant amount. UAN32 was 7% more expensive compared to a month earlier. The nitrogen fertilizer had an average price of $282 per ton.
The remaining seven fertilizers were all higher compared to the prior month, but none were up a significant amount. DAP had an average price of $466 per ton, MAP $503/ton, potash $350/ton, urea $368/ton, 10-34-0 $421/ton, anhydrous $503/ton and UAN28 $237/ton.
Anhydrous is above the $500-per-ton level for the first time since the second week of June 2017. That week, the price was right at $500 per ton.
On a price per pound of nitrogen basis, the average urea price was at $0.40/lb.N, anhydrous $0.31/lb.N, UAN28 $0.42/lb.N and UAN32 $0.44/lb.N.
Newly released research shows farmers who farm in the western Lake Erie area of northwestern Ohio are following the guidelines for fertilizer rate and application practices, according to an Ohio State University (OSU) newsletter. This comes after algae-infested water, thought to be caused by fertilizer runoff, contaminated Toledo's water supply in 2014.
However, the report points out that more steps need to be completed to limit agricultural runoff from farm fields into the rivers that feed into Lake Erie.
The Soil and Water Conservation Society (SWCS) published its findings in a special issue of the Journal of Soil and Water Conservation, the OSU report stated. The research shows that up to 80% of farmers in the region are following the most up-to-date guidelines for fertilizer application.
While this may be the case, the study also concludes that the recommendations need to be re-examined to better protect the western part of Lake Erie from pollution from agricultural runoff.
"But even though the vast majority of growers are applying nutrients at or below recommended the levels, the reality is that roughly 70% of the phosphorous entering Lake Erie is from streams and rivers, where agriculture is often the dominant land use," said Doug Smith, USDA soil scientist, who co-authored the article in the Journal detailing the research.
"So we have to acknowledge that the agronomic data and information on which farmers are basing their fertilizer application decisions may not be giving enough consideration to the importance of minimizing nutrient runoff into western Lake Erie."
Smith said many farmers in the region still follow fertilizer recommendations developed 40 years ago or more. Many changes in tillage methods, crop varieties and nutrient formulations have happened during this time.
The science that drives fertilization practices needs to catch up, Smith said.

Five fertilizers are now higher compared to last year with prices pushing higher in recent months. UAN32 is now 1% more expensive, urea is 2% higher, potash is 4% higher, DAP is 5% more expensive and MAP is 9% higher than last year.
The remaining three fertilizers are lower in price compared to a year prior. Anhydrous is 1% less expensive while UAN28 is 4% lower and 10-34-0 is 5% lower looking back a year.
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.
