Ammonium Sulphate Liquor
Trials conducted at the Institute of Grassland and Environmental Research have illustrated that Sulphur has a more significant role in utilisation of Nitrogen than scientists first thought. A 3-year trial programme on a sandy loam site comparing Ammonium Sulphate treated plots with those where Ammonium Nitrate was used concluded the following:-
 |
Dry matter yields were increased by up to 38% with Ammonium Sulphate |
|
Nitrate leaching was reduced by up to 72% with Ammonium Sulphate |
|
Nitrogen efficiency was increased by up to 39% with Ammonium Sulphate |
|
Peak Nitrate in the drainage water was reduced by up to 400% with Ammonium Sulphate |
|
Lorna Brown stated "The results surprised us as the experiment worked so well. It wasn't just in the first year the marked difference was seen as significant." Ms Brown carried on "Farmers should see the inclusion of Sulphur in their grassland management as an important element." |
|
The 1983/84 GRI Annual Report stated that "Yields of herbage were higher and more consistent with Ammonium Sulphate than with Ammonium Nitrate." |
|
Following a series of field experiments investigating the effects of Sulphur supplementation on cereals, ADAS Senior Research Scientist Paul Withers stated that "...the cost of fertiliser supplementation is small relative to the benefits gained if deficiency is prevented. Growers in risk areas would be better advised to omit P and K than S." |
|
Sulphur is one of the major plant nutrients and the correct ratio of Sulphur to Nitrogen is essential to the plant. The application of high levels of Nitrogen, as in grass conservation, can interfere with this balance. In fact, recent studies show that up to 30kg per hectare of Sulphur may be removed from grassland each year. |
|
Less Sulphur is now being replaced by atmospheric pollution, and within the next ten years levels are expected to be below those required by most UK crops. |
|
Trials in Britain and in the United States have shown that increasing Sulphur levels in grass, cereals and sugar beet has reduced fungal disease levels, and often given considerably higher yields. |
The Sulphur balance is automatically corrected using Ammonium Sulphate Liquor, which contains a unit of Sulphur for every unit of N. |
