21 FOR IRRIGATED CORN - at planting, apply
30 to 40 lbs nitrogen per acre banded by the row. Sidedress the balance of the
nitrogen in three applications. Apply the first portion of the balance when
corn plants are 12 inches tall, apply the second portion when the plants are 24
– 30 inches tall, and apply the third portion 2 weeks later through the
irrigation system. When following soybeans or other legumes in rotation, reduce
the nitrogen rate by 20 to 30 lbs nitrogen per acre.
22 FOR NON IRRIGATED CORN - At planting,
apply 30 to 40 lbs nitrogen per acre banded by the row. Sidedress the balance
of nitrogen in two applications. Apply the first half of the balance when corn
plants are 12 inches tall and the second half of the balance when corn plants
are 24 – 30 inches tall. When following soybeans or other legumes in rotation,
reduce the rate by 20 to 30 lbs nitrogen per acre.
23 Higher yield goals may only be
obtainable through irrigation and other proper cultural practices.
25 Broadcast recommended phosphate and
potash fertilizer and magnesium-, zinc- and sulfur-containing fertilizer when
recommended, during land preparation prior to planting.
28 This is a boron sensitive crop. Apply
0.5 lbs boron per acre in fertilizer. (Recommended when soil test boron is less
than 3.0 lbs per acre)
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)
201 Use a plant analysis to
ensure that plants contain adequate levels of all nutrient elements. Deficient
nutrient elements can be sidedressed or added in the irrigation water. Contact
your local County Extension Agent for additional information.
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)
