Corn is called a heavy feeder, which means that you need to fertilize often and well in order to provide enough nutrients for the plants to grow. Thankfully, this is not usually an extra chore for you, since you should prepare your entire garden plot before planting anything.
What nutrients do corn plants need?

When to use N fertilizer for corn?

When you indicate on the soil-test questionnaire that your corn crop will follow a legume crop, the adjustment in the N fertilizer recommendation will be given.
How do you remove nutrients from soil?
The major removal of any nutrient from soil, however, is through plant uptake, whether the plant is the desired crop or a weed. Uptake eliminates the chance of nutrient loss through any of the above processes. Some conservation of nutrients as well as of soil, therefore, can be achieved with the use of a winter cover crop.
How is N used in soil?
Available N may be used by soil bacteria when there is abundant high-carbon, low-N organic matter such as corn stover. The bacteria need additional N and can tie up available N and temporarily prevent its use by plants or its loss by other means. This is most likely in no-till corn production where N fertilizer is surface applied and corn stover is left from previous seasons. Since immobilization is temporary, there is no difference in the optimum N rate among different tillage or no-tillage methods of production. While immobilization can occur with very high rates of bedding added to the manure, this is usually not a problem at typical rates of bedding use.
Why is mineral N important to soil?
However, because mineral N is sensitive to environmental factors, a chemical analysis of soil before planting cannot indicate the N availability other than right at the time the sample was taken and , therefore, is unable to predict soil N availability throughout the growing season.
Do you need to adjust the N recommendation for legumes?
Recommendations may need to be adjusted. Adjustments to the N recommendation for the residual N from a legume are automatically made when a previous legume crop is indicated on the soil test questionnaire. If manure is applied, you will need to make adjustments in the N recommendation for the amount supplied by the manure. See the Penn State Agronomy Guide for details on these adjustments.

Does urea help corn?

What happens when pollen touches silk?
Pollination occurs when pollen touches the strand of silk. This seems like pollination should be easy. The pollen drifting down from the tassel should pollinate the ears below, right? Wrong! 97 percent of an ear’s pollination comes from other plants, which is why it is important to know when and how to pollinate corn.
How long does it take for corn to pollinate?
To pollinate corn efficiently, wait until the tassels are fully open and beginning to shed the yellow pollen. This usually begins two to three days before silk emerges from the embryonic ears. As soon as the silk emerges, you’re ready to begin the manual pollination of corn.
What is the male flower on a corn plant?
The male flowers are called the tassel. That’s the part that looks like grass gone to seed that blooms at the top of the stalk. As the tassel ripens, pollen is shed from the center spike downward to the lower fronds. The female parts of the stalk are the ears located at leaf junctions and the female flowers are the silks. Each strand of silk is connected to one kernel of corn.
What is the role of wind in corn?
In larger fields, wind takes care of corn pollination. Between air circulation and stalks jostling one another in the wind, there is enough natural agitation to spread the pollen. In smaller garden plots, the gardener takes the place of the wind and the gardener needs to know when to do the job as well as how.
Can you hand pollinate corn?
How wonderful it would be to reap a bounty of corn if all we needed to do was drop the seeds in their little hole and watch them grow. Unfortunately for the home gardener, manual pollination of corn is almost a necessity. Even if your plot of corn is fairly large, learning how to hand pollinate corn can increase your yield and help prevent those sterile stalks that are often found along the edges of your planting. Before you learn about hand pollinating corn, it helps to know a little about the plant itself.
Where do the flowers on a tassel ripen?
As the tassel ripens, pollen is shed from the center spike downward to the lower fronds. The female parts of the stalk are the ears located at leaf junctions and the female flowers are the silks.
