13  This is a manganese sensitive crop.  Apply 10 lbs manganese per acre with the fertilizer when manganese deficiency has been observed in previous years.  When manganese deficiency symptoms occur, confirm by a plant analysis.  Apply manganese as a foliar spray either singularly or mixed with a pesticide.  Make one or two applications of 1 lb manganese per acre. 

19  If silage is grown for more than 1 year, increase potash rate to 200 lbs potash per acre after the first year.  (When soil test potassium is low)

20  If silage is grown for more than 1 year, increase potash rate to 100 lbs potash per acre after the first year.  (When soil test potassium is medium)

32  Apply inoculum on soybean seed when soybeans have not been planted within 3 years or when planted in sandy soils.

33  Reduce nitrogen fertilizer rate by 20 lbs nitrogen per acre for Piedmont soil.  (For Soil Code 4)

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)

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)
