Urea Fertilizer Application Rate
Nitrogen leaching and volatilization rates are usually higher when using the prilled form. Therefore granular urea fertilizers are 15-20 more efficient than prilled.

Urea fertilizer application rate. Urea provides a cost-effective way to add an important nutrient to your soil. Often sold as granules you spread around your garden. How Quickly Is Urea Fertilizer Available to Plants.
To determine the fertilizer rate for a particular nutrient multiply the rate of the desired nutrient by 100 and divide by the percentage of the nutrient in the fertilizer. It is generally a solution of 05 and 2. Urea application rate - 50 lb Nacre example rate.
12 rows If you want to apply fertilizer on a maize plot of a land area say 350sqm at a recommended. For Urea which contains 46 nitrogen the formula would be 10046 217 lb. Urea itself has an alkaline effect upon the soil initially so the higher the rate of application the higher the soil pH change in the zone around the urea particles.
Urea 46000 and single superphosphate 088011 Apply Calculation A. Fertilizer rate required nutrient application rate X 100 nutrient in the fertilizer. Also used as a non-protein nitrogen supplement for ruminants cattle and sheep.
Lets see a few examples. How many pounds of urea he needs to apply. Therefore depending on the quality of your soil we recommend 2-3 pounds per 1000 sqft.
Three treatments with the application of super granular urea SGU application rates of 23 46 and 69 kg N ha 1 one treatment with the application of conventional urea CU fertilizer 46 kg N ha 1 and one control without any N fertilizer application laid down in a randomized complete block design. However the solution for a foliar spray is different. Urea fertilizers are highly soluble solubility of 1079 gL at 20ºC.
All rates are in pounds actual N per acre divide by 046 to get pounds of 46-0-0 per acre. Urea anhydrous ammonia and liquid urea ammonium nitrate UAN 28 or 32 are by far the most common sources of nitrogen fertilizer used in corn production. Moreover all 3 sources of nitrogen fertilizer have their own unique advantages and disadvantages but in particular dry urea is an exceptionally poor source of nitrogen for in-season applications to corn.
A grower wants to apply 50 pounds of nitrogen to his 6 acres field using Urea 46-0-0 fertilizer. Rate urea 20 units N 46N x 100 435 kgha urea Rate single superphosphate 20 units P 88 x 100. When applying to soil the urea fertilizer application rate varies according to the plant and season.
You can usually get it in dry granular form. As a general albeit not scientific rule of thumb the formula for determining the application rate for nitrogen divide 100 by the percentage of nitrogen in the compound and apply the result to 1000 sqft. The table below illustrates APPROXIMATE rates of urea 46-0-0 N that can be safely applied with cereal grain seed if seedbed soil moisture is good to excellent moisture at or near field capacity.
Fertilizer application rate 50 x 100 46 1087 lbs. UREA FACT SHEET April 2017 Most widely used and most concentrated solid nitrogen N fertiliser 46 N. A surface application of 200 pounds of nitrogen per acre as urea about 444 pounds of actual urea per acre has been shown to increase surface soil pH from 65 to above.
The field experiment comprised five treatments ie. Both prilled and granular urea fertilizers contain 46 N. There are several benefits to using urea as a fertilizer but urea.
Urea Fertilizer Application Rate is a stable organic fertilizer that can improve the quality of your soil provide nitrogen to your plants and increase the yield of your crops. In the paddock you need 20 kgha N and 20 kgha P. Cost per ha costtonne x rate kgha from A 1000 Example.
Example 1 Recommended rate of N is 80 lbac Using 46-0-0 the rate of fertilizer required is. 80 x 100 46 174 lbac Example 2. Suitable for dry application to the soil and in solutions to the soil and in foliar sprays.
