Danish company HPGen™ improves crop yields in Spain

When HPNow's precision irrigation and agronomy experts assessed the site, it was clear that clogging of drippers leads to non-uniform irrigation and insufficient water and fertilizer delivery to part of the crop. To mitigate this, farm personnel were going through the drippers frequently to "unclog", a manual process highly costly in man-hours.

Organic matter

Soil quality was also analyzed and the amount of organic matter in the soil, a critical parameter for the healthy growth of the plants, was very low at 0.33%. This is due to poor dissolution of organic matter fertilizers in water, which further exacerbates dripper clogging and decreases crop productivity. To overcome these issues, an HPGen™ system was installed and integrated with the drip irrigation system. The HPGen™ was installed in the irrigation room and set to automatically fill a buffer tank with Peroxide UltraPure™. Dosing was done through a proportional dosing pump, which is both simple and effective.

Improved yields

After a season of cucumber crop with HPGen™, yields were compared to previous seasons. The results with HPGen™ were of 17 kg/m², a record for this grower, substantially higher than the average for the past 5 years of 12 kg/m². In addition, the grower observed the quality of the fruit improved, and the fruit could remain on the plant longer, allowing for optimization in harvesting depending on market prices.

The improvement in >40% in production is explained by two factors:

ˇ       Better irrigation uniformity: After two weeks of installing the HPGen™ all drippers showed a uniform water flow, which allows for an optimal distribution of water and fertilizer throughout the field.

ˇ       Increase of soil organic content, which increased by a factor of 10 (from 0.33 to 4 %), which contributed to improving plant nutrition.

Both factors are due to the high oxidizing power of the Peroxide UltraPure™ generated by the HPGen™ system, which oxidizes organic matter in the irrigation system and makes it available to the crop. This results in a better health and vigor of the plants, and in an improvement in yields.
