How much nitrogen do you put on a sidedress corn?

Depending on soil type and cropping history, 60 to 70 percent of your nitrogen should be applied at or before planting if you are planning on sidedressing your corn crop.

How do I calculate how much fertilizer I need?

You should apply 10 pounds of the fertilizer per 1,000 square feet (five pounds from the table multiplied by the two pound recommendation). * When using a soluble inorganic nitrogen fertilizer a typical recommendation is to use only one pound of nitrogen per 1,000 square feet for a single application.

Can you put too much nitrogen on corn?

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.

How many pounds of nitrogen per acre are needed for 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.

How much fertilizer do you need per acre?

Fertilizing an Acre of Lawn Multiply the number of bags you need for 1,000 square feet by this number to determine how many bags you need for an acre. For example, you need (1.1 x 43.56) = 48 bags of Dr. Earth and (0.25 X 43.56) = 11 bags of Pennington UltraGreen.

What is the best fertilizer for sweet corn?

Nitrogen fertilizer suitable for fall sweet corn should have a mineral content specifically created to enhance the corn plant’s growth. For corn, use a fertilizer labeled “16-16-8,” which describes the mineral composition in the fertilizer: 16% nitrogen, 16% phosphate and 8% potassium (following an N-P-K formula).

What is a good starter fertilizer for corn?

Under most situations, a combination of nitrogen and phosphorus constitutes an effective starter material. Liquid 10-34-0 and dry 18-46-0 are common starter fertilizer materials. Liquid 7-21-7 and dry 8-32-16 are also commonly used.
