How much nitrogen is in a bushel of corn?

Approximately 14 lb of N was needed to produce one bushel of grain with the greatest rate of applied N (300 lb/acre). In comparison, it took 1.6 lb of N to produce one bushel of grain with the lowest rate of applied N (60 lb/acre) (Figure 3).

How much nitrogen does your crop require per acre?

So if you look at nitrogen, it’s pretty straight-forward. “For 150 bushels, we recommend 180 pounds of nitrogen per acre. For 200 bushels, you go up to 240 pounds, and for 250 bushels, go to 300 pounds. For 300 bushels per acre, we recommend more than 360 pounds of nitrogen per acre,” he says.

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. … Excess nitrogen can be lost by leaching or runoff or by passing off as vapor through volatilization, potentially polluting the air or water systems.

How many pounds of fertilizer does it take to grow an acre of corn?

For corn, if the fertility level is good, a small amount of fertilizer (about 100 pounds of starter per acre) will provide an adequate starter response. Do not apply more than 70 pounds of N + K2O per acre if the fertilizer is placed approximately 2 inches away from the seed.

Does corn like nitrogen?

Corn Needs for Nitrogen Because N is a constituent of all protein within the corn plant, it is needed in high quantities.

What kind of fertilizer does corn like?

Fertilize the plants with a 16-16-8 liquid fertilizer when the corn plants have reached a height of 4 inches, but before it reaches 8 inches tall. Also add a few inches of organic mulch when the corn is 3 or 4 inches tall.

What is the best 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.

Does corn need a lot of fertilizer?

Pre-Planting Fertilizer Sweet corn requires plenty of nitrogen and phosphorus throughout the growing season. … An all-purpose fertilizer containing more nitrogen and phosphorus than potassium — such as a 16-16-8 ratio fertilizer — helps ensure healthy growth when applied to the soil before planting.

Is corn a nitrogen depletion or fixer?

Corn requires large quantities of nitrogen for its growth. Commercial corn production relies on substantial inputs of synthetic fertilizer. … These bacteria fix atmospheric nitrogen that would otherwise be unavailable to the plant.

How often can you fertilize corn?

Lightly cover and work the fertilizer into the soil. Apply the additional high-nitrogen fertilizer a total of two to three times during the growing season and be sure to follow all package instructions.

How much fertilizer do I need for 200 bushel of corn?

A 200-bushel corn crop will take up about 265 pounds of N per acre, 115 pounds of phosphorus pentoxide (P₂O₅), 265 pounds of potash (K₂O), 65 pounds of magnesium (Mg) and 33 pounds of sulfur (S).

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.

When should nitrogen be applied to sweet corn?

The right stage to apply nitrogen fertilizer is between the V8 and VT (when the fully matured plant is shedding off pollen) growth stages, which is about 30 days. Between the laying by and the V8 stages, plan to apply the nitrogen fertilizer.

When should you put nitrogen on corn?

When should I apply nitrogen? The crop needs little nitrogen during early vegetative stages to about the fifth leaf development stage. The largest portion of the total nitrogen taken up by corn occurs during the eighth leaf to VT (tasseling) development stages. Nitrogen uptake is mostly done shortly after pollination.

How do you add nitrogen 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.

How much nitrogen does a sidedress need?

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. This allows you to evaluate growing conditions and maximize profit.

Why is it important not to over apply nitrogen?

To grow, plants require nitrogen compounds from the soil, which can be produced naturally or be provided by fertilizers. However, applying excessive amounts of fertilizer leads to the release of harmful greenhouse gases into the atmosphere and the eutrophication of our waterways.

Is cow manure good for corn?

“Cattle manure is good fertilizer. … His research in 2006 and 2007 in northern and central Illinois showed that the N fertilizer rate for the subsequent corn crop can be reduced by about 13% when half or more of the residue is removed.
