"A strong root system makes the plant more resilient." Pepper grower Rob Moors – Moors Nursery, Asten-Heusden - Netherlands.

A pepper grower, Moors Nursery has invested in the quality of their irrigation water in recent years. Rob Moors invested in Moleaer’s technology, an innovative system that adds high concentration of oxygen and nano-sized bubbles to the irrigation water. After seeing excellent results from a large pilot on 8 hectares in 2023, Moors decided to implement Moleaer’s technology at all three of his locations, covering 25 hectares by the end of 2024. 

A strong root system of a bell pepper plant looks like this in a substrate mat, says Moors. “When we open the mats, we see a homogeneous root system with beautiful white, high-quality roots and many fine hair roots. In the case of a weak or sick plant, we see many brown and even black roots.”

Since May 2022, Moors has used Moleaer's water treatment technology at one of his three cultivation sites. Throughout the growing season, the root system quality in the mats was repeatedly tested, and the results were good. “The root system of the plants at this location was visibly better than at the other locations without Moleaer. That was the determining factor in our decision at the end of 2023 to install Moleaer units at all cultivation sites. At our location in Someren, we had plant losses in one section last year, hence this choice.”

The importance of irrigation water quality. The quality of irrigation water is crucial in cultivation; it needs to be rich in oxygen and free from pathogens as fungi can easily spread through water. Higher oxygen levels in irrigation water result in stronger, more resilient roots and plants, reducing the impact of fungal infections. It works both ways. Moors uses spring water as the base for his cultivation, which is purified through iron removal and osmosis. The next step is enriching the irrigation water with oxygen. Moleaer units are connected to the day supply water and fertilizer silo with a capacity of 350 cubic meters. One Moleaer unit continuously adds oxygen nanobubbles by recirculating water.

Moleaer’s Oxygen Nanobubbles. Moleaer’s is a nanobubble generators adds minuscule oxygen bubbles and elevated levels of dissolved oxygen to the water. "These are bubbles with a diameter of 100 nanometers; that's as small as a virus," says René Mondt, Technical Specialist at Royal Brinkman,“At Moors Nursery, we choose to enrich the irrigation water with 30 mg of oxygen per liter. The oxygen dissolves very well in the water, with a transfer efficiency of 85% SOTE (Standard Oxygen Transfer Efficiency), much higher than other technologies. With Moleaer, you can cost-effectively and efficiently supersaturate the water with oxygen. The extra oxygen in the irrigation water allows the root system to develop better. And a strong root system provides the plant with a stable base, which it needs during stressful moments in cultivation.” René adds, “Moleaer’s technology is of high quality, producing oxygen with 93% concentration. For comparison, the oxygen content in the outside air is only around 21%. Moreover, oxygen enrichment with Moleaer is chemical-free. We add no substances to the water, only oxygen.”

About Moleaer
Moleaer is an American-based nanobubble technology company with a mission to unlock nanobubbles’ full potential to enhance and protect water, food, and natural resources. Moleaer has established the nanobubble industry in the U.S. by developing the first nanobubble generator that can perform cost-effectively at municipal and industrial scale. Moleaer’s patented nanobubble technology provides the highest proven oxygen transfer rate in the aeration and gas infusion industry, with an efficiency of over 85 percent per foot of water (Michael Stenstrom, UCLA, 2017).

About nanobubbles
Nanobubbles are tiny bubbles, invisible to the naked eye and 2500 times smaller than a single grain of table salt. Bubbles at this scale remain suspended in water for long periods, enabling highly efficient oxygen transfer and supersaturation of dissolved gas in liquids. Nanobubbles also treat and eliminate pathogens and contaminants of emerging concern as well as scour surfaces to break apart biofilm matrices, creating a powerful, sustainable, and chemical-free disinfectant (Shiroodi, S., Schwarz, M.H., Nitin, N. et al., Food Bioprocess Technol, 2021).
