Urea storage
Urea fertiliser should be kept in a closed, secure store to protect the product from both the weather and the risk of theft.
Store your urea in an area that is:听
- Protected from moisture 鈥� this avoids the fertiliser from lumping together听
- Away from direct sunlight 鈥� this can affect the fertiliser packaging听
- Free of dust and dirt听
- Of a temperature between 5掳C and 30掳C
Stacking fertiliser
Be sure to stack them on a level surface in a stable arrangement, such as with a pallet rack.
Remember that urea is not as stable when stacked compared to ammonium nitrate, so it may be more prone to falling over.

Urea calibration
Calibrating a fertiliser spreader ensures that the right amount of urea product is landing in the right place across the whole of the field.
Different fertiliser products require different settings, depending on its manufacturer.
Fertiliser producer Yara have produced a handy guide that can help you to find the spreader settings for the fertiliser spreader that you use:
The key elements to get right are:听
- The spreader height from the ground
- The angle at which the fertiliser hits the discs听
- The flow rate.
To be sure that a spreader is set up correctly, a tray test can be carried out before working across the rest of the field.
Under Option 4, growers may be switching to coated urea from 1 April each year.
The required settings may be different to those for the uninhibited urea used prior to this date, so recalibration may need to take place prior to application.

Urea application
Knowing how to properly apply urea fertiliser will help you to get as much benefit out of it as possible 鈥� be sure to consider these four factors:听
- Crop requirement 鈥� Be sure to consider the needs of your crops and to provide additional nutrient when its demand is greatest.
- Wind 鈥� The weather, and in particular wind, can have a significant impact on the success of a urea application. Strong winds will lead to an uneven spread of product across the field, whilst damp or humid conditions will affect the flow rate of the urea onto the discs.
- Speed 鈥� Variations in speed will also affect the spread of urea across the field, so it is best to stick to a consistent speed.
- Headlands 鈥� Don鈥檛 forget to account for headlands when working across the field, and pay particular attention to watercourses.
