You swap the nozzles on the boom and nothing else. Your sprayer, your products and your way of working stay exactly as you know them. The difference shows on water-sensitive paper: finer droplets, spread more densely and evenly across the surface.
Aquadea GmbH, Schloss Sulzemoos. Developed and manufactured in Bavaria.
Four points that matter in day-to-day operation. The technology behind them is explained further down, where those who wish to check the figures will find the measured values.
In the same trial, at the same application rate, the deposit lies more densely and evenly on the paper. This also holds for leaves that are difficult to wet, such as brome.
The nozzles fit the usual nozzle bodies. There is no pump, no device in the tank, no new controls and nothing that can break down on you during the season.
The nozzle works physically, not chemically. Crop protection products, foliar fertilisers and biological preparations are applied as before, and microorganisms do not pass through any device in the tank.
A titanium body, a ruby outlet and no plastic in the flow path. The working range of 1.0 to 30 bar leaves you free to choose your forward speed.
Water-sensitive paper turns blue wherever a droplet lands. Both strips come from the same trial, at the same forward speed and the same application rate.
Images from the comparative trial carried out by Aquadea GmbH. The strips show the distribution of the droplets, not the efficacy of any product.
A finer spray pattern is not an end in itself. Here are four consequences that can be explained physically, each shown with the current state of the data.
For the same volume, a finer droplet spectrum covers more leaf area. What stays on the leaf can be taken up; what runs off or falls between the rows cannot.
Visible on water-sensitive paper
Ultrafine bubbles attach to water-repellent surfaces and lower the wetting energy. On grasses and brassicas, this decides whether a droplet adheres or runs off.
Demonstrated in the laboratory, field studies under way
The measured zeta potential of −28 mV keeps like-charged droplets apart. They coalesce less and retain their size distribution. This expressly does not mean a recognised drift reduction according to the JKI (Julius Kühn Institute, the German federal research centre for cultivated plants); please see the notice further down.
Plausible in terms of colloid chemistry, agricultural studies under way
The bubbles only form as the liquid leaves the nozzle. Microorganisms do not pass through any device in the tank, and at the target the like charge counteracts their adsorption onto soil particles.
Plausible, field evidence still pending
We do not promise you higher efficacy of approved plant protection products, nor a reduced application rate. Such a statement requires repeated field trials. Until these are available, we show the physical route towards it and the observations from farms for what they are.
Please adhere to the approved application rate and to the product label.
With foliar fertilisers and plant strengtheners, such as rock dust or EM (effective microorganisms), users report an enhanced effect. These are reports from practice, not trial results.
Observations from farms
Three processes in the nozzle head, all within the last few centimetres before the plant. If you would like to know more, you will find the measured values and an assessment of the evidence below.
01
The water is set in rotation inside the chamber. This creates very fine micro- and nano-vortices before it reaches the outlet.
02
At the reversal point of the nozzle, the pressure drops locally. The chamber draws ambient air into the water stream according to the Venturi principle.
03
The shear forces in the channel break the air up into bubbles smaller than one micrometre. They reach the leaf fresh and in full number.
Measured in the emerging liquid using nanoparticle tracking analysis. In colloid chemistry, a zeta potential beyond 20 to 30 millivolts is considered electrostatically stable, which means the bubbles repel one another instead of coalescing.
Nanoparticle tracking analysis of two samples dated 18 May and 1 June 2026: 12.2 and 12.1 million bubbles per millilitre. Depending on water quality, the measured zeta potential lies between −25 and −30 mV; hard water with a high calcium and magnesium content shifts the value towards zero. The figures refer to the samples tested and do not constitute a guaranteed property.
Systems that generate bubbles in the tank have existed for years. The difference lies in where the bubbles are formed, and this has four practical consequences.
The nozzle generates the bubbles during normal application. Nothing changes in your routine on the farm.
Only seconds pass between formation and the leaf. Ageing and coalescence in the tank do not occur.
Formulation adjuvants, pH buffers and biological preparations do not encounter an upstream generator.
The air shearing works physically, not chemically. It can be combined with common spray products.
For crop protection, plant strengthening and foliar feeding in arable farming and in land and amenity maintenance. Both sizes fit the usual nozzle bodies.
We distinguish between measured values, laboratory findings and mechanisms that are physically plausible but have not yet been tested for arable farming in published field studies.
| Mechanism | What lies behind it | State of the data |
|---|---|---|
| Better wetting of the leaf surface | Bubbles accumulate at the interface with water-repellent surfaces and lower the wetting energy. | Demonstrated in the laboratory, field work under way |
| More stable droplets in flight | Like-charged droplets coalesce less and retain their size distribution better. | plausible in terms of colloid chemistry |
| Finer dispersion of EC and SC formulations | The shear forces in the chamber break up the active ingredient phase, similar to a high-pressure homogeniser. | Analogy, agricultural studies lacking |
| Protection of biological preparations | Microorganisms do not pass through a generator in the tank; at the soil, the like charge has a repelling effect. | plausible, field evidence outstanding |
| Oxygen input during irrigation | The greatly enlarged interface increases the transfer of oxygen into the water. | well documented in hydroponics |
Five nozzles were fitted on one side of a sprayer with a 36-metre working width. During a pass in lentils, the farm manager noticed that the crop on that side was developing differently. The passes concerned became visible in the drone’s multispectral images and later also in the combine harvester’s yield map.
This is an observation from a working farm, not a randomised replicated trial. The plots were not laid out with replications, and differences between sites cannot be ruled out. We are providing the images because they are the reason for our ongoing trials.
CERES nozzles do not have a recognised drift reduction class according to the JKI. They must not be used where plant protection law or the product label requires drift-reducing equipment approved by the JKI, in particular under the conditions NW605 to NW609, under NT conditions, and in areas protecting water bodies and nature. For these applications, only listed nozzles with the corresponding reduction class are permitted.
We look at your spraying equipment, your water quality and your crops, and tell you which nozzle size is suitable and where the technology reaches its limits.
