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.

18 With each 10 bushel per acre yield increase over 30 bushels per acre, the potash recommendation has been increased by 10 lbs per acre.

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

202 When preparing soil for planting, broadcast phosphate and potash fertilizer and magnesium-, manganese- and sulfur-containing fertilizer when recommended.

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)

648 Availability of boron decreases substantially as pH increases above 6.5. Boron applications in irrigated soybeans or at high soil pH should be based on leaf concentrations of boron. Soybean yield will respond positively to foliar applied boron when concentrations in leaves are 10 ppm or less. In such instances when boron is needed, it should be applied at 0.2 lbs per acre at the early-pod stage (1/8 to 1/4-inch pods) and can be mixed with insecticides if needed.

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)

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)

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)
