How do I give my corn nitrogen?
Spread the nitrogen in a line on the soil surface about 6 inches from the row of corn. Water the corn as usual to help carry the nitrogen down to the root systems. Add nitrogen one last time once the sweet corn ears begin producing silk, using 46-0-0 nitrogen fertilizer according to product application directions.
Does corn require nitrogen fertilizer?
Corn Needs for Nitrogen Because N is a constituent of all protein within the corn plant, it is needed in high quantities. When deficient, normal growth and development is thwarted.
What kind of fertilizer does corn need?
Apply three to four pounds of 10-10-10 fertilizer per 100 square feet. Fertilizer should be broadcast evenly and worked into the top two to three inches of soil prior to seeding. When corn is 12 inches tall it is a good idea to apply a sidedressing of fertilizer. This is especially important on light sandy soils.
When should nitrogen be applied to corn?
Ideally the N should be applied just prior to this period of high N demand. For most corn hybrids N uptake is complete shortly after pollination. So, most of the N should be applied prior to the 10 leaf stage, with any supplemental applications complete by or shortly after tasseling.
What is the best form of nitrogen for corn?
Smart nitrogen or polymer-coated urea is a suitable nitrogen source for sweet corn and only needs to be applied once. Cost, however, is higher than urea. Sweet corn is a heavy user of nitrogen.
How much nitrogen do you put on a sidedress corn?
Sidedress applications allow growers to maximize profits. However, each growing season has varying precipitation and different environmental conditions that can prohibit producers from applying nitrogen in-season. For each bushel of corn removed, 1.5 pound of nitrogen is required.
How much nitrogen should I put on corn?
An estimate of N requirements for corn is 1 lb of N is needed for every bushel of grain produced, so a 200 bu corn crop would require 200 lb of N.
Is cow manure good for corn?

Can corn get too much nitrogen?
Nitrogen is the most expensive nutrient used in corn production. If applied properly, it makes individual plants stronger and increases yield. “Beyond some level of applied nitrogen, grain yield stops increasing with more additions,” said co-author Bob Nielsen, Extension corn specialist.
Should you water corn everyday?
Corn has deep roots, so you need to water long enough that water reaches a depth of 30–36 inches. Because corn benefits from deep, soaking watering, it’s best to water once per week rather than daily, as this ensures adequate soil moisture.
Is there a best way to fertilize corn with nitrogen?
There is no such thing as a perfect way to apply nitrogen for top corn yields. The sloppiest surface application can work well if conditions are favorable, but a sound approach is the best way to achieve good results most of the time. Corn farmers know that the application of nitrogen fertilizer is a critical factor in the production of corn.
Does your corn still need nitrogen?
Corn Needs for Nitrogen Because N is a constituent of all protein within the corn plant, it is needed in high quantities. When deficient, normal growth and development is thwarted. In fact, N stress at any time during a corn plant’s life will subtract from yield, much like drought, insect feeding, disease pressure or other stresses.
How much nitrogen is required for growing corn?
Corn plants use large quantities of nitrogen to grow and yield. Corn removes 1 pound of nitrogen for every bushel of grain produced, so a 250 bushel per acre yield goal requires 250 pounds of nitrogen available to be used by your growing corn plants.
