Those 4 criterias are essential to allow a precise and even spreading with a good coefficient of variation (CV).
The CV quantifies the average deviation of doses applied in relation to the mean dose, and is stated as a percentage. The lower the CV, the better the distribution.
Granular AN from Borealis L.A.T guarantees a superior and consistent physical quality.
Compare to prilled product, granular AN from Borealis L.A.T always offering a better coefficient of variation (CV) at all spreading widths and for all wind speed.
In windy condition, prilled AN cannot be spread up to 36m with a correct CV, a uneven spreading will lead to yield loss. At 36m, only granular AN offers a good CV, even in windy condition.
UK is predominately a windy country, on the 3 months of the fertiliser application season from March to May, there is only 6 days per month without wind above 15km/h and 13 days without wind above 25km/h.
Those 6 days correspond to the avalaible days to correctly spread prilled AN. Due to is performance in windy conditions, granular AN can be spread on an average of 19 days per month during the spreading season, giving more flexibility for the farmer.
