Potato trial: UAN stabilized with DeltaLent Active 1.3
We have conducted a trial on potatoes in Tournai, North-West of Belgium. In this trial we tested DeltaLent Active 1.3 on UAN, this UAN existed out of 15% ureic N, 7,5% ammonium N, 7,5% nitric N. The dosage used was 1300g DMPP/t UAN and 0,58% DMPP / NH2+NH4.
- Soil type : loam
- pH (KCl) : 7,4
- Humus : 2,4%
- P2O5 content: very high
- K2O content : high
- MgO content : medium
- 200 N/ha – 1 application
- P2O5 : Starter in the row
- 150 K2O/ha
- Magnesium sulphate applied by spraying
The results of the trial are very promising: an increase of 1,7% yield per hectare. For this trail this means an increase of 751 kg or €150 (depending on sales price and season) per hectare. Application cost are <€50 per hectare resulting in a net profit of +/- €100 per hectare!
DeltaLent Active 1.3 is very easy to use because there is no additional equipment required for application, you just add the solution to your slurry. Next to that, another advantage is that the crystallisation risk is reduced and if there is any crystal, the addition of hot water to dissolve them.
