Sidedress application of liquid fertilizer is especially effective in supplementing or restoring nitrogen. However, sidedress application can be used for many other macronutrients
Plant nutrition
Plant nutrition is the study of the chemical elements and compounds necessary for plant growth, plant metabolism and their external supply. This is in accordance with Liebig's law of the minimum. There are 14 essential plant nutrients.
Micronutrient
Micronutrients are nutrients required by organisms throughout life in small quantities to orchestrate a range of physiological functions. For people, they include dietary trace minerals in amounts generally less than 100 milligrams/day-as opposed to macrominerals which are required in larger quantities.
What is side dressing in fertilizer?

Can you over fertilize corn?
Fertilizer makes plants grow fast; but too much fertilizer results in weaker plants, not stronger ones. Sweet corn (Zea mays), for example, requires nitrogen and phosphorous to thrive, but too much nitrogen produces stalks so weak that they fall over like felled trees.
When should I stop fertilizing my corn?
It is an extremely light feeding that helps seeds to establish quickly without burning them out. The second fertilizing comes as the corn reaches around 4 weeks of age. This dose, as with the final application (at 8 to 10 weeks) needs to be more powerful to allow the plant to produce big stalks and full ears.
Does urea burn corn?

By applying nutrients, as needed, it allows crops to grow while poor soil is being amended. Side dressing should be a continued act of maintenance for your garden even after the soil quality improves. It’s a wonderful way to replenish necessary nutrients.
How long does it take for a plant to be side dressed?
Typically, plants can be side dressed three weeks after they’re planted, when the plants are approximately six inches tall, when they form leaves, or when they begin to flower.
Can you use granular fertilizer on plants?
In most cases, plants lack nitrogen. Every plant needs nitrogen to grow properly. Therefore, there never seems to be enough in any planting area. When you know the timing for applying fertilizer and which nutrients must be added, use a granular fertilizer for side dressing. You may also use compost.
Do heavy feeders need to be fertilized?
It’s vital to understand which category each of your plants fall under. Plants that are heavy feeders should be fertilized on a frequent and regular basis. Plants which thrive from neglect, may need their nutrients supplied during the planting process. After this time, they’ll most likely prefer to be left alone.
Why sidedress nitrogen?
Sidedressing N when the plants are small can reduce root pruning and minimize plant injury. Sidedressing nitrogen (N) in addition to pre-plant N application in corn has several advantages compared to pre-plant applications only. Some of the benefits include providing N closer to when it is needed by the crop, reducing the potential for N losses, ...

Broadcast dry ammonium nitrate, ammonium sulfate, or urease inhibitor treated urea. Surface dribbling UAN solution. Broadcast UAN.
How to determine the best N fertilizer for in season?
To determine the best option for an in-season N application, consider the source of N to be used, crop growth stage, and the ability to minimize N loss. After considering these factors, injecting N fertilizer between rows is often the best option. With applications between rows, N is kept at a safe distance to avoid crop injury and is placed where the crop roots will be growing. Also injecting or incorporating N minimizes the potential for N loss.

What happens when you put dry products on a field?
In some fields, crops are getting tall and some still need additional nitrogen. Application of dry products, such as ammonium nitrate and urea, “over the top” can result in foliar damage. Typically, this damage is an aesthetic concern and rarely translates into yield reduction.
What happens if you apply nitrogen over the top?
Application of dry products, such as ammonium nitrate and urea, “over the top” can result in foliar damage. Typically, this damage is an aesthetic concern and rarely translates into yield reduction. Over the top applications of UAN are the least desirable way of applying nitrogen.
Why is it important to watch soil conditions to ensure that the knife track closes properly?
If ammonia is used for the application , it is important to watch soil conditions to ensure that the knife track closes properly to avoid foliage damage by free ammonia escaping to the atmosphere. When injecting or dribbling are not viable options, broadcast applications of nitrogen would be the next alternative.
When to apply nitrogen to corn?
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. Thus, applying N before the V8 development stage is best. Research has shown that if applications are done around V6, it is very rare to see yield loss due to N stress.
Who is Fabian Fernandez?
Fabian Fernandez, nutrient management specialist at the University of Minnesota Extension, says producers have a lot of questions when it comes to sidedressing nitrogen. The questions are usually about when to apply nitrogen, what are the best options for sidedressing and if the crop is tool tall, can nitrogen be applied "over the top."
Do you need to apply more nitrogen to a crop?
But your earlier application may have been subject to loss. If you had a lot of leaching in heavily tiled fields, soils with a lot of natural drainage, or denitrification in waterlog soils, you may need to apply more nitrogen.
What is the most common fertilizer used in New England?
Common fertilizer sources of N used in New England include urea, ammonium nitrate, diammonium phosphate, monoammonium phosphate, calcium nitrate and potassium nitrate. In the soil, urea is converted by hydrolysis to ammonium, which in turn is converted through nitrification to nitrate.
What is the N in poultry manure?
Up to half the N in dairy manure and 75% of the N in poultry manure is readily converted to nitrate-N. A large part of the N in legumes is converted to nitrate shortly after plow down. Pre-plant incorporation of manures and legumes can result in leaching risks similar to fertilizer N.
How to apply N to a crop?
Supplemental N is typically applied during the growing season as a sidedress or topdress. A sidedress application involves placing a band of N into the soil at a desired distance from the row of plants and is done with a fertilizer applicator mounted on a cultivator. The machine should be adjusted so that the fertilizer band is far enough from the crop row to avoid root damage by the equipment. For a topdress application, fertilizer is broadcast over the entire field, usually with a spin-type spreader. Most of the fertilizer granules bounce off the plant, but a few remain on the leaves. The adhering granules can burn the leaves, leaving small dead spots. Other than leaf crops, this injury is not much of a problem, but if the leaves are moist during application, more fertilizer sticks to the foliage and serious leaf burn can occur. Many growers cultivate the crop after topdressing to incorporate the fertilizer, and others try to apply it just prior to rain or irrigation, which can move soluble N into the soil. Some growers are using liquid solutions of N in water. Typically, these are sidedressed. There are no significant differences between liquid or dry materials from a horticultural standpoint. The main considerations in deciding which of these to use are equipment and convenience.
How does N management affect crop yields?
Good N management involves supplying the right amount at the right time for crop needs. Lack of sufficient N can reduce yields , but any N in excess of crop needs is subject to leaching. Studies in New York have shown that even a small amount of over-fertilization with N increased nitrate levels above drinking water standards in ground water. In one study, when N was applied to corn at 30 lbs/A above the optimum rate, 40% of the excess was lost to leaching. The study was done on a sandy soil, typical of many agricultural soils. Leaching becomes less likely as soil texture becomes finer.
What is the best way to reduce leaching risk from pre-plant N?
Leaching risk from pre-plant N applications can be reduced somewhat by using a slow release N fertilizer such as sulfur-coated urea. Soil organic matter, compost and residues from previous crops are generally considered to be slow-release sources of N, but certain organic sources of N are readily available.
