What nitrogen does to corn?

Perhaps the major role it plays in all plants is as a component of chlorophyll, the green pigment in plants, that is essential for photosynthesis. Adequate N availability in corn allows the plant to reach its genetic yield potential.

How much is a unit of nitrogen?

If the N-P-K rating is 10-6-4, for example, and the weight of the bag of fertilizer is 25 pounds, the fertilizer bag contains 2.5 pounds of nitrogen. The one unit of nitrogen in this case would be 1 pound.

When should nitrogen be applied to corn?

How much nitrogen do you put in sweet corn?

The level of nitrogen fertility has more influence on the growth and yield of sweet corn than any other single plant nutrient because it is the nutrient most often deficient in Arizona soils. With good management, a total of about 175 to 225 lbs. N per acre is usually needed for optimum production.

How much nitrogen does corn require per acre?

How do you sidedress corn with nitrogen?

What are the best options for sidedressing nitrogen? Injection into the soil or dribbling the nitrogen fertilizer between rows are the best ways to sidedress because this application can reduce volatilization of urea and protect the crop from foliar damage.

How do you give nitrogen to corn?

Fertilize the plants again when they are about 10 inches tall. This is best done by side-dressing, rather than applying fertilizer directly on the young plants. For this application use a 46-0-0 (all nitrogen) fertilizer product. Spread the nitrogen in a line on the soil surface about 6 inches from the row of corn.
