Treatment Options

Apply Copper onto crops subject to excess Nitrogen or Phosphorus; crops grown on high pH or heavily limed soils; crops grown on peat or muck  soils with high organic matter; crops grown on leached out acid soils  or sand; or when the conditions are cold and wet in the spring, delaying the availability of Cu. Soils high in Manganese content can reduce the availability of Cu.
