Very Low Ammonia Emissions

YaraBela Axan creates half the emissions of urea plus inhibitor

"No longer will yield be the only measure of success, lower ammonia emissions will be high on everyone's agenda"

UK agriculture must reduce ammonia emissions by 8%

Fertiliser accounts for 23% of ammonia emissions

Emissions from nitrate fertilisers are less than 3%

Why are ammonia emissions now so important?

UK Agriculture has to reduce ammonia emissions by 8% of the 2005 baseline by 2020.
Fertiliser application accounts for 23% of agricultural ammonia emissions with nitrate based fertilisers being the lowest emitters.

Reducing ammonia emissions with nitrate fertilisers

YaraBela Axan nitrate based fertiliser has one of the lowest ammonia emissions of all nitrogen sources.^*
Ammonia emissions from nitrate fertilisers are below 3%.^*
Ammonia emissions from nitrate fertilisers are half those of urea + inhibitors. ^*

Mineral fertiliser with no added chemical inhibitor

YaraBela fertilisers already have lower emissions than urea plus an urease inhibitor so don't need to include an inhibitor.
YaraBela fertilisers are purely mineral fertilisers without any added chemicals such as a urease inhibitors.
Sulphur rapidly degrades urease inhibitors so adding sulphur to urea plus inhibitor is not a good idea.
Urease inhibitors degrade during storage so should be spread as soon after application as possible.

Best use of nitrogen

YaraBela Axan contains sulphur and nitrogen which increases nitrogen use efficiency and means more for your money with less wastage

"A lack of sulphur often reduces nitrogen use efficiency, meaning that crops cannot make the best use of nitrogen as the two nutrients work hand-in-hand."

Nitrogen and sulphur should always be applied together

Sulphur should be applied 'little and often' throughout the growing season

Making the best use of nitrogen

Nitrogen needs sulphur to work efficiently, so if you think you are seeing nitrogen deficiency it may well be caused by a lack of available sulphur.
Manage sulphur levels proactively to maximise nitrogen use efficiency.
There is little point in spending more money on nitrogen if you haven’t spent any on sulphur.

How to best managing your sulphur

Crops need a regular supply of sulphur throughout the growing season, so a little and often approach to sulphur management is essential.
Sulphur is immobile in the plant so cannot be moved from old to new leaves when it is needed, this means fresh sulphur is still needed later in the season.
Same as nitrogen, sulphur can be readily leached through the soil so shouldn't be applied 'all at once'.

Every £1 spent on sulphur gives £4.60 return in extra yield

Adding sulphur can boost cereal yields by upto 2t/ha

Sulphur deficiency could cost you £128/ha

Can you afford to ignore sulphur deficiency?

Over 90% of soil samples are deficient in sulphur
Every £1 spent on sulphur gives £4.60 return in extra yield
Sulphur increases nitrogen use efficiency, giving you more for your money and less wastage
Sulphur deficiency this year could cost you £128/ha

Accurate Spreading

YaraBela Axan can be spread more accurately and more evenly over wider bout widths

YaraBela fertilisers enable accurate spreading of all nutrients

YaraBela fertilisers are all uniform whereas blends tend to be quite variable and come in different shapes, sizes and densities.
Uneven application of nutrients can occur when spreading a blended fertiliser as a result of physical segregation
Spreader calibration with blends is always a compromise due to the different ballistic properties of various constituents.
Changing to a YaraBela compound fertiliser containing sulphur and nitrogen will ensure an even spread of both nutrients
There are up to 6 times more sulphur landing sites with YaraBela Axan compared to Ammonium Sulphate.

Smoother harvest

Bigger yields

Faster spreading

Can you afford not to use quality fertiliser?

Even application of nutrients means more even crops, resulting in less lodging, reduced drying costs and smotther harvesting.
Reduced spreading variability results in an even crop and increased yields (co-efficicent of variation or cv of 10% with YaraBela vs 34% typical of blended fertiliser).
Ability to spread accurately over wider bout widths saves time spent spreading and reduced application costs.

Recommended nitrogen plus sulphur fertilisers

The following YaraBela fertilisers contain nitrogen plus sulphur and are recommended for all crops.

YaraBela AXAN

27% N + 9% SO3 - Granular uniform compound nitrate based nitrogen and sulphur fertiliser for use on all crops.

YaraBela SULPHAN

24% N + 15% SO3 - Uniform compound nitrate based nitrogen and sulphur fertiliser for use on all crops, particularly those with a higher sulphur requirement.

Sulphur management in cereals

Getting the most from your sulphur applications is critical for both yield and quality so it is worth reviewing your current practice to make sure you get the best response from sulphur.

Don't forget about sulphur

Sulphur was often overlooked in the past but today it is recognised as an essential nutrient and considered just as important as nitrogen, so not to be forgotten.

When is the best time to apply sulphur ?

It is generally accepted that sulphur is an essential nutrient for all crops but there is still some confusion over the best time to apply sulphur.
