  • Abstract:
    Three multi-year corn (Zea mays) experiments ranging from 5 to 15 years in length were planted to soybean in 2016. The three multi-year experiments all had a range of phosphorus treatments that had developed soil test phosphorus levels from 5-60 ppm Mehlich III. Two studies had no P applied in 2016 and one had the same phosphorus treatments as when corn was grown. Response to soil test P level will be compared to the University of Nebraska critical level. The experiments were conducted at the Haskell Agricultural Lab in northeast Nebraska under rainfed conditions.
