AN 33.5 N versus Urea

In an ever-changing landscape the pressures to manage increasing yield demands alongside environmental sustainability is a constant challenge.  

Legislation and best practice continue to determine growers choices particularly when it comes to Nitrogen and with a focus on ammonia emissions, choosing the right N source is vitally important.


This can be achieved by utilising Directly Available Nitrogen (DAN) fertilisers.


Directly Available Nitrogen (DAN) fertilizers, based on nitrate and ammonium, combine the benefits of the two simplest forms of reactive nitrogen that are directly available to plants. Promoting this efficient source of nitrogen for plant nutrition is an initiative of Fertilizers Europe, and with the support of LAT Nitrogen., DAN fertilizers help farmers increase food and energy production in an environmentally effective and efficient manner.

Granular Urea is more susceptible to high ammonia losses through volatilisation, even if applied early. This means that AN based products remain the best option for UK agriculture. LAT Nitrogen Granular Nitrogen product lines outperform Granular Urea in terms of quality, superiority of spreading, reliability for yields and improved crop quality. They don’t rely on a chemical change in order for nitrogen to be available and are not weather dependent with regards to application windows.  


With our product- and service-offer we support farmers to adhere to the golden rule, which says: using the right product at the right dose, at the right time and at the right place.


Our highly efficient crop nutrition solutions offer precise and reliable means of increasing agricultural production in an environmentally acceptable way. We are deeply committed to enhancing efficiency while reducing the environmental impact at the same time, focusing on the safety and high standards of our products

High quality granulated AN based fertilizers

OUR GRANULAR FERTILISER RANGE CONSISTS OF:


Nitrogen fertilisers                        


Nitrogen plus sulphur fertilisers


With natural deposition of sulphur negligible and the availability of it through organic manures variable, our MYNITRAS® granular compounds are ideal to meet all crop demands throughout the season.

Using the right form of nitrogen


Volatilisation can affect all fertilizers containing a significant proportion of urea and ammonia nitrogen. Urea and urea ammonium nitrate solution (UAN) are highly sensitive to ammonia volatilisation. The nitrogen that escapes into the air is lost and not available for plant nutrition!


This means that nitrogen fertilizers containing nitrate such as those from LAT Nitrogen are more effective!


Ammonia volatilisation adversely affects the environment and the efficiency of the fertilizers used. It is therefore important to select the right form of nitrogen.


LAT Nitrogen AN 33.5. N is perfectly fitting for UK and Ireland agricultural needs throughout the year!

Excellent CV with granulated fertilisers

The physical characteristics of granulated fertilizers have a significant influence on the spreading pattern by affecting the behaviour of the granule in the spreader and the way it travels through the air. It is important that these properties do not alter during storage. 

The evenness and precision of spreading depends directly on the quality of the fertilizer.

Especially the granular AN 33.5 N from LAT Nitrogen fulfills the mentioned requirements to achieve such a good CV.


The lower the CV, the better the distribution. The quality of fertilizer distribution is expressed as follows:
A CV between 0% and 10% is excellent
A CV between 10% and 15% is good
A CV between 15% and 20% is poor
A CV above 20% is unacceptable


Imprecise spreading can have serious consequences. It is often visible in strips or waves, showing 30% over or under-dosing. Uneven and imprecise distribution of fertilizer leads to nutrition deficiencies in the plants, resulting in a yield and protein reduction. Too high a dose  than the economic optimum causes a loss in revenue and increases the risk of nitrogen loss.

Precise spreading of solid fertilizer (CV < 10%) means that over 90% of the granules have landed in the right place. That level of precision means that 1 gram of nitrogen per square metre can be applied to achieve 100kg per hectare. Such precision is only available with high-quality homogeneous fertilizers such as those from LAT Nitrogen.

That is why we have a dedicated sales force located in the UK and Ireland focussed on delivering and meting our customer expectations through a network of strategically selected distributors. Due to the close proximity to our plants, we are able to deliver our granulated fertilisers nationwide all year round.


Closely situated to the UK and Irish market, we have the ability to ship vessels from Grand Quevilly in a quick and efficient manner ensuring continuity of supply. 


Our product portfolio for the UK and Ireland is focused on high quality granulated nitrogen and nitrogen sulphur fertilisers all optimally sized to ensure perfect strength and density.  These products are perfectly suited to optimise yields for both arable and grassland growers with physical qualities that provide excellent CV at all spreading widths, even in windy conditions.


Investment in our production facilities have significantly reduced the amount of times our fertilisers are handled, thus maintaining product integrity and ensuring a superior and consistent fertiliser quality.  


Resellers and farmers value this proximity to the market and our reliability in supply of high quality products.
