Kaiser: Phosphorus Pays Off Despite Higher Fertilizer Costs

As fall harvest progresses, farmers are planning out their fall fertilizer applications. University of Minnesota Associate Professor of Crops and Nutrient Management Dan Kaiser shared his recommendations for the Red River Valley. “There’s a fair amount of soils up there that are low in phosphorus,” said Kaiser. “Those are areas that we know that even with higher prices, as long as you’re not grossly over-applying, typically we get a positive return on investment.” Kaiser says farmers should be cautious about fertilizers with too many additives in them. “I think we’ll see some of these additives coming out of the woodwork, just trying to claim higher efficiency of it. I just have my doubts, especially for growers who are in situations that have high pH soils.”
