Want to achieve a superior spreading pattern?

"Achieve better yields as a result of evenly distributed spreading patterns with granular AN"

How solid is your farming knowledge?

The following factors are important for even spreading

When spreading with a centrifugal distributor, it is very important to consider the overlap distance in order to ensure an even distribution. This is because the concentration of granules decreases as the distance from the spreader increases. The speed of driving also influences the distribution.

spreader adjustment

Fertilizer spreading machines must be adjusted for a given fertilizer with a predetermined working width. Spreader adjustments are provided by the manufacturers and include the following variables:


Output = dose in kg/ha x working width x movement speed


Working width = distance between two adjacent passes of the spreader. It is also the distance between the overlap points between passes.


Over the last 25 years the broadcasting distance that spreaders can achieve has increased from 24 to 36 meters or even greater. The farmer must make sure that the fertilizer spreading machine is suited to the required width, and select fertilizer that is also appropriate.

ADJUSTING YOUR SPREADER

To ensure precise spreading and thus even distribution for effective nutrition, it is crucial to adjust the spreader correctly. The fertilizer ranges from Borealis L.A.T are referenced for spreaders from major manufacturers.

Information about the factory origin is also provided.


Based on the information provided on the bags (before the batch number) in manufacturer’s databases, the origin is specified as follows:


  • “GP” for Borealis Grandpuits
  • “GQ” for Borealis Grand-Quevilly
  • “OTT” for Borealis Ottmarsheim
  • “St.-Peter-Straße 25, 4021 Linz” for Borealis Linz


Please note that the manufacturing plant is also stated on the documents accompanying the product.

GRANULAR AN: OPTIMISE YOUR SPREADING PATTERN

Physical quality is the key factor for a precise spreading.

Those 4 criterias on the right picture are essential to allow a precise and even spreading with a good "coefficient of variation (CV)".


The CV quantifies the average deviation of doses applied in relation to the mean dose, and is stated as a percentage. The lower the CV, the better the distribution. 


Borealis L.A.T granular AN 33.5 N fulfills the most important facts for a superior spreading pattern and a precise CV. 


Excellent supply chain

Our facility at Grand Quevilly has undergone huge investment over the last 2 years.  Increasing its production and export capabilities has allowed us to meet the demand throughout Europe for good quality Nitrogen products without compromising product integrity.


Closely situated to the UK market, we have the ability to ship vessels from Grand Quevilly in a quick and efficient manner and have developed and grown strategic relationships in order to ensure continuity of supply to UK growers throughout the year.


Beyond 36m

Up to 25km/h

More than 19 days

Beyond 36m

Compared to prilled products, Granular AN from Borealis L.A.T offers a better coefficient of variation (CV) at all spreading widths and at all wind speeds. In windy conditions prilled AN cannot be spread up to 36m with a correct CV and uneven spreading will lead to yield loss. At 36m, only Granular AN offers a good CV even in windy weather.

Up to 25km/h

At 25 km/h crosswinds the tests show that Granular AN 33.5 still maintains a good spreading pattern and a correct CV, unlike the prilled products. This unique benefit of Granular AN is giving the farmers confidence to go out spreading while achieving good results.

More than 19 days

3 times more days of applications in the spreading season is only assured by Granular AN 33.5. UK weather makes the farmers work schedule hard to maintain consistently. During the high season there are only 6 days with wind speeds below 15km/h, but with Granular AN farmers can spread confidently an additional 13 days when the wind speed is up to 25 km/h.

Prilled AN or Granular AN? What insures better spreading & yield?
