“The yield of blueberries has improved thanks to the production of hydrogen peroxide”
The Huelva region in southern Spain is an important agricultural area. Dry soil and a warm climate, combined with the use of organic fertilizers, however, can be difficult for growers. A 24-hectare blueberry plantation in Huelva, part of an organization producing high-quality organic berries, turned to HPNow for help.
In collaboration with farm operators and leading agronomists, HPNow analyzed the site and assessed how to improve blueberry yields. Two main problems have been identified:
1. Clogging of drippers leads to uneven irrigation and insufficient supply of water and fertilizer to part of the crop, resulting in loss of production. Up to 30% of the drippers were clearly clogged, despite extensive use of industrial oxidants.
2. Poor dissolution of organic fertilizer in irrigation water, leading to low levels of organic matter in the soil, which hinders plant growth. Analysis showed that the organic matter content was 0.33%.
On top of that, the costs associated with these issues were high, with the replacement of drip lines up to twice a year, as well as the manpower used to identify and replace clogged drippers and chemical costs. to attempt to clean the irrigation lines. To overcome these problems, an HPGen system was installed and integrated into the irrigation system. Half of the field (12 hectares) was treated with UltraPure Peroxide generated directly on site by the HPGenTM, while the other half remained with a standard weekly treatment with chemicals.
After only six weeks of operation with the HPGen, field operators observed that all drippers in the treated section were leaking, differently from those in the untreated section where 30% remained clogged. The soil quality was analyzed once more and was found to be greatly improved. The results indicate that the organic matter levels fell from 0.33 to 0.80%. Improvements in culture were also clearly visible after six months of treatment, with more plant vigor and vegetative growth six months after starting Peroxide UltraPure dosing. The plants in the treated section could be directly compared to a section without treatment, where all other parameters were kept the same as the section treated with HPGen.
Comparing the two sections, Senior Agronomist Jose Garcia Meca said: “In the untreated area the plants are smaller and germination is significantly smaller than in the area treated with HPGen.” The drippers in the treated area were evaluated by the field operator of producer Jose María, who concluded: “The HPGen treatment allowed all of the drippers to be cleaned.” In addition to uniform irrigation, the organic matter content of the soil increased from 0.33% to over 0.8%.
Better growth, higher returns
With these results, the crop is well irrigated and receives the nutrients it needs, which clearly translates into better growth and higher blueberry yields. The results are explained by the oxidizing power of Peroxide UltraPure, which will keep the irrigation lines clear, while oxidizing the positive organic matter in the irrigation lines and making it available for cultivation. This ensures that the irrigation lines are clean and the drippers flow, getting water and fertilizer evenly throughout the field while improving plant nutrition.
