63 This is a
zinc sensitive crop. Fertilizer should contain sufficient zinc to supply 5 to
10 lbs zinc per acre. (When soil test zinc is not excessive)
159
Broadcast 40 to 60 lbs nitrogen per acre and the recommended phosphate and
potash and work into the soil 3 weeks prior planting. Band-place 20 lbs each of
nitrogen, phosphate
and potash per acre with the planter. Sidedress with 50 to 75 lbs nitrogen per
acre when the plants are 12 to 18 inches tall. On very sandy soils, sidedress
with 40 lbs nitrogen per acre when plants are 3 to 6 inches tall and another 40
lbs nitrogen per acre when plants are 12 to 18 inches tall.
241 This is a
boron sensitive crop. Apply with broadcast fertilizer 1 to 2 lbs boron per
acre. (When soil test boron is not excessive)
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)
