Advanshield Nitrogen-Protected Fertilisers

With concerns over air quality and leaching, AdvaNShield’s range provides protected nitrogen which can be combined with our agronomically optimised sulphur grades to meet emerging regulatory requirements and end-customer demands.

AdvaNShield makes your investment in nitrogen work harder. It provides a cost effective and patented water soluble polymer nitrogen stabilisation technology working with the soil to naturally help crops absorb the nitrogen they need for longer.

How AdvaNShield Works

AdvaNShield reduces nitrogen losses by maintaining higher levels of the nutrient in the ammonium form in the soil, which growing crops can use more efficiently. 
 
AdvaNShield is based on Verdesian’s NutriSphere-NL inhibitor.  The technology relies on a long-chain organic water-soluble compound made up of maleic acid and itaconic acid.  
 
When the two acids are combined, they reduce the availability of nickel, copper and iron to retard the bacterial conversion of ureic, ammonium and nitrate ions into forms of nitrogen that can leach, volatilise and be lost to the crop.  This includes gaseous ammonia which is lost to the atmosphere.
 
AdvaNShield delivers significant agronomic and environmental benefits
Nitrogen available in the soil for longer
Reducing Ammonia volatilisation to the air
Reducing leaching of nitrogen to groundwater
with the prospect of additional yield without harming soil bacteria, fish or other fauna like earthworms or leave a soil residue.
 

The Benefits

Reducing wasteful ammonia and nitrous oxide losses by upto 54% means fewer emissions and cleaner air. Field-scale experiments have shown that for some crops on some soil types a single application of nitrogen is possible both reducing energy-intensive field operations and easing spring workloads in tight weather windows.

AdvaNShield Protected Nitrogen makes a contribution towards helping you meet Net Zero and farming more efficiently

Replicated trials in three European countries including the UK tested AdvaNShield over three seasons and demonstrated the following benefits: 

Higher yields – 4% increase in crop yield.
Less pollution – 24% reduction in leaching.
Cleaner air – 54% reduction in nitrous oxide emissions.
More efficient – 4.5% improvement in nitrogen use efficiency.
