Key Conclusions
H2Flo increased potato yield by 7%, starch content by 9%, and increased farm income by €283/ha.
Objective
To demonstrate how application of H2Flo results in a better horizontal and vertical water penetration, increasing irrigation efficiency, and resulting in a higher yield and positive return on investment.

Treatments
H2Flo treatment consisted of a total of 5.5 L/ha of H2Flo in 3 applications using boom sprayers (spray volume 1,000 L/ha).
| Treatment | Date | Application |
|---|---|---|

| 5 July 2015 | 1.5 | |
| 2 August 2015 | 1.5 | |
| Total | 5.5 |
All treatments received the same fertilizer regime and the same irrigation through rain guns (9 applications totalling 225 mm of irrigation).
Harvest measurements were performed by the Swedish Society of Agriculture, Kristianstad trial.
