Grain Sorghum, Sweet Sorghum, or Sugarcane

34  Broadcast one-half of recommended nitrogen prior to or at planting, and then the remainder as a sidedress. 

315  If plants show iron deficiency symptoms (yellow tissue between green veins on upper leaves), apply chelated iron following label directions for the material used, or apply a 2% solution of ferrous sulfate including a surfactant applied at a rate of 120 to 180 gallons per acre.  Apply the iron-containing solution to the foliage in the late afternoon when the air temperatures are warm and only to plants that are being adequately watered and fertilized.  (Recommendation when soil pH is above 6.0)

651  The soil test boron is low, however, this is not a boron sensitive crop, therefore no boron is recommended.  (When soil test boron is low)

652  The soil test manganese is low, however, this is not a manganese sensitive crop, therefore no manganese is recommended.  (When soil test manganese is low)

653  The soil test zinc is low, however, this is not a zinc sensitive crop, therefore no zinc is recommended.  (When soil test zinc is low)

Sunflower

12  This is a boron sensitive crop.  Apply 0.4 lbs boron per acre in the fertilizer or in the insecticide spray in either one or several applications so long as the total boron applied does not
exceed 1.0 lb boron per acre.  (Recommendation when soil test boron is less than 3.1 lbs per acre)

34  Broadcast one-half of recommended nitrogen prior to or at planting, and then the remainder as a sidedress. 

652  The soil test manganese is low, however, this is not a manganese sensitive crop, therefore no manganese is recommended.  (When soil test manganese is low)

635  The soil test zinc is low, however, this is not a zinc sensitive crop, therefore no zinc is recommended.  (When soil test zinc is low)
