Wheat does not require large amounts of N until stem elongationjointing Feekes Growth Stage 6 which is generally the middle or the end of April depending on the location in the state and spring temperature. Nitrogen applied early has the potential to be lost since wheat will use little N prior to jointing Feekes GS 6.

Methods for Applying Topdress Nitrogen to Wheat potential for N losses due to volatilization when using any urea-containing fertilizer.
. Fall-applied ESN should be incorporated. Urea will have little potential for loss as long as it does not volatize. No stabilizer will protect the nitrate component of.
Applying 28 nitrogen UAN as an overall broadcast treatment using flood jet or tee-jet nozzles to emerged. Leaf nitrogen levels must be maintained through to anthesis and applications of nutrients such as phosphate magnesium and boron should be considered to maximise yield. Applications made earlier risk loss during rainy periods.
Late planted winter wheat benefits from an early N application to encourage tillering as the crop begins to green up. Ad Find Deals on organic nitrogen fertilizer in Gardening Tools on Amazon. Excessive N can encourage more vegetative growth and increase.
Cereals are very responsive to nitrogen. The best time to apply nitrogen is around mid-March just before the wheat begins to grow rapidly. This means estimating the amount of N needed and estimating how much of the N might be lost due to excessive rainfall and saturated soils.
Michigan State University Extension recommends approximately 11 pounds per acre of fertilizer N per bushel of. Apply approximately half in late January and. The short answer.
Early spring is the time wheat growers implement nitrogen N fertilization strategies. ESN may be applied in fall for spring wheat similar to recommendations for application at planting on winter wheat. By contrast the risk of lodging is greater in early planted fields with high seeding.
Wheat fields with 30-49 3 leaf tillers per square foot in late Januaryearly February can receive a split topdress N application. Ohio research has shown no yield benefit from N. This can be reduced or eliminated by 1 streaming the liquid N 2 using flood nozzles 3 mixing 12 water 4 applying less than 60 lbac of N per application or 5 avoid applications on cold windy days.
A good split N strategy in this scenario is 60 of N 10 lb of S in the first application and 40 of N in the second application. Assume an average grain protein of 114 for a feed wheat which equates to 2 nitrogen then yield would be 1522 x 100 76tha at 100 dry matter or 87tha at 15 moisture. Conditions are cool enough at the time of wheat topdressing however that N losses from urea due to volatilization are not a major concern most years.
The most frequent problem encountered when broad-. When should nitrogen be applied to wheat. Nitrogen on winter wheat.
As it gets later in the spring responses will decrease and the rate of. Adequate N early in the growing season is important to support healthy tillering and to give young plants the best opportunity to survive the sometimes-harsh South Dakota winter. Urea-ammonium nitrate UAN or 28 has the greatest potential for loss and ammonium sulfate the least.
The entire growing season of spring wheat will be between 90 and 120 days compared to. If the field has 50 or more tillers but is showing signs of N deficiency you may apply 30-40 units of N in late January early February and the rest at Growth Stage 30. In many cases wheat is still prior to or just beginning to joint so the application rates should be 50 to 70 pounds nitrogen per acre.
The amount of nitrogen applied during this time should be enough to bring the total amount of nitrogen applied in February and March to the 60-90 lbac range. Although the burning of wheat with liquid N looks bad there is little research evidence. These applications should comprise a high percentage of the total N as ESN preferably 100 ESN to protect against over-winter and early spring nitrogen loss.
Leaf burn can be a concern with liquid nitrogen. It has been known for long that split-applying nitrogen N can be an effective practice in winter wheat. Wait until green-up to apply N to wheat.
However over-application of nitrogen or applying too early on a thick stand of wheat can cause lodging resulting in reduced yield quality and harvestability. Exactly how much nitrogen should be applied is a function of stand growth stage and the amount of nitrogen applied last fall.
