Analysis

During initial climb after takeoff, the ag plt realized that he could not clear wires at the end of the rwy. The plt dumped his load of fertilizer and attempted to maneuver around the wires, however during the maneuver, the acft stalled. Investigation revealed that ground personnel had substituted ammonium nitrate for urea in the fertilizer load, increasing the acft's gross weight by 800 lbs. The plt was not made aware of the substitution prior to takeoff. By volume, ammonium nitrate is heavier than urea.
