Using nitrogen and oxygen to purify water, and then using the new compounds as fertiliser. It sounds too good to be true, but the company VitalFluid has developed a method that makes it possible. The method is currently being tested in an organic tomato crop, according to American standards, at the WUR in Bleiswijk.
Nitrogen treatment gives slightly more vegetative crop
After a technical problem, cultivation for the project started in July and will continue until December. Because of this postponement, lighting will also be used to make cultivation possible at this time of year.
The first harvest is expected in early September. In the meantime (mid-August), the researchers have noticed a small difference between the treatments; the control treatment is slightly less vegetative compared to the VitalFluid treatment. The cause of this is being investigated, writes Jim van Ruijven of the WUR at Glastuinbouw Waterproof.
More updates will follow in the coming months.
