The Benefits of Liquids

A liquid fertiliser system requires less manual handling of bags from store to the field, less machinery involved amounting to fewer staff engaged on fertiliser application.   Deliveries and replenishments are made to field side tanks located around the farm by drivers guided by GPS co-ordinates.   It all adds up to a more efficient and productive way of producing food, which in a post-Brexit world, should allow UK Agriculture to compete more effectively in global markets.

UAN is better agronomically

Liquid Nitrogen is contains Nitrogen that comes 50% from Ammonium Nitrate and 50% from Urea. This means that UAN contains 25% is nitrate and 25% ammoniac and 50% ureic which means that it has less susceptibility to leaching than AN

UAN can be applied more evenly and precisely

With the move to wider bout width, liquid fertilisers can be precisely metered onto crops evenly and reliably to the full width without the risk of uneven application or spreading into field margins and hedgerows.

Quality Product

Nowadays Urea Ammonium Nitrate Solutions [UAN] is imported ready-made by ship-tanker from the same factories that make AN or Urea – the liquid is hived-off before the prilling stage.   It is difficult to make UAN in the UK from scratch owing to the tight rules relating to off-spec Ammonium Nitrate and detonation resistance regulations.  UAN is More Concentrated than Pure Urea or AN mixes

A pure urea solution can dissolve to 18% Nitrogen Content [used for foliar ear-wash for milling wheat in June]. A pure AN solution will dissolve to about 20% but is quite corrosive. Mixing the Urea and Ammonium Nitrate together allows upto 30% Nitrogen by the ‘shared water of crystallisation’ phenomenon.

Sulphur: Sources

Nowadays about 2/3 of the UAN sold in the UK contains sulphur,. Sulphur sources can be from Sulphate of Ammonia [dissolved from solid] or Ammonium Thiosulphate liquor.

Less Plastic Waste

This year we have particularly noticed that growers using liquids have valued significantly less waste generated on their farms responding to consumer concerns about single-use plastic waste, which has dominated the media and ultimate purchasers of farm-gate products

More Efficient

A liquid fertiliser system requires less manual handling of bags from store to the field, less machinery involved amounting to fewer staff engaged on fertiliser application.   Deliveries and replenishments are made to field side tanks located around the farm by drivers guided by GPS co-ordinates.   It all adds up to a more efficient and productive way of producing food, which in a post-Brexit world, should allow UK Agriculture to compete more effectively in global markets.

Optimised Machinery

With tanks placed strategically around the farm, there is no need for farmers to keep spare loaders, trailers and barn storage for liquid fertilisers. It is a true one-man operation.
