Dean Sanders · Grazing Property

A grazier reports cutting irrigation from nightly to twice weekly while nearly doubling stocking on the same hectare, with no fertilizer applied. Entirely self-reported, with no meters and no control paddock.

Conducted by Video interview between Jody Spencer of President Water and grazier Dean Sanders, recorded as promotional content. No measured data and no control comparison.

LOCATION: Western Australia
PERIOD: One season, as described on camera. Exact dates not stated
EQUIPMENT: President Water vortex generators, one-inch and two-inch models

KEY FINDINGS

What the trial measured

Irrigation and stocking on the same hectare

THE STANDOUT RESULT

Irrigation frequency fell from every night to roughly twice a week.
Reported water use of about 100,000 to 200,000 liters a week, replacing roughly 100,000 liters every two hours overnight.
Stocking on the one-hectare paddock went from about 15 head to 20, then to 29.
At 29 head the grower reports cattle could not keep pace with grass growth.
No fertilizer or soil inputs were applied during the season described. Pasture was maintained on cattle manure alone.
All of these are spoken recollections. Nothing was metered, logged or independently verified.

Water storage and pasture

At the same point in the season, 1.5 of three farm dams remained full.
In prior years all three were typically empty by May.
A side-by-side shot in the video contrasts an unirrigated paddock, dormant with no cattle all summer, against the vortex-irrigated paddock.
Cattle were observed to graze the vortex-served area preferentially, which the grower attributes to sweeter grass.

Fruit trees at the homestead

The first unit installed went on fruit trees at the house rather than the paddock.
Fruit yield reportedly tripled after installation.
Newly planted trees, which would normally take one to two years to bear, reportedly fruited in their first year.
No yield measurements, comparison trees or records are referenced.

“Cattle preferentially graze the area served by the vortex-treated sprinkler, which the grower attributes to the grass being sweeter in that zone.”

WHY THIS MATTERS

The stocking figure is what a grazier will react to. Nearly doubling head on the same hectare while cutting irrigation to twice a week is a large claim, and it is the kind of thing a neighbour can see over a fence rather than something that needs a laboratory.

The dam levels are the most checkable thing in the interview. Water in storage in May, against three empty dams in prior years, is a physical fact on the property rather than an interpretation.

Everything here is spoken. There is no meter on the irrigation line, no stock record, no control paddock, and no rainfall figure for the season being compared against prior years. The interviewer works for the company selling the unit. That does not make it untrue, and it does mean this belongs in a different bucket from the Marri Park meters or the SR TAFE beds.

Read it as one grazier's account of his own paddock. If the numbers hold on a metered follow-up they would be remarkable, and a metered follow-up is exactly what this deserves.

METHOD

Trial at a glance

OPERATION: Grazing property, one-hectare irrigated paddock plus homestead fruit trees
EQUIPMENT: President Water vortex generators, one-inch and two-inch models
BEFORE: Nightly irrigation, roughly 100,000 liters every two hours overnight, about 15 head
AFTER: Roughly twice weekly, about 100,000 to 200,000 liters a week, up to 29 head
FERTILIZER: None applied during the season described. Cattle manure only
WATER STORAGE: 1.5 of three dams still full in May, against all three empty in prior years
MEASUREMENT: None. All figures are spoken recollections on camera
CONTROL: None. A visual comparison against an unirrigated paddock only
INTERVIEWER: Jody Spencer, President Water
FORMAT: Promotional video testimonial produced by President Water

WORTH NOTING

Findings that cut against the headline. We publish them because a grower deciding on a retrofit deserves the whole picture.

Single property, single paddock, not replicated, with no control paddock, randomisation or independent measurement.
Every figure, including irrigation volumes, frequencies, stocking numbers and dam levels, is a spoken recollection rather than metered, logged or third-party verified data.
The video was produced and distributed by President Water as promotional content, and the interview was conducted by a President Water representative.
No soil, water or forage testing accompanies the account. There is no biomass, nutrient or Brix measurement.
Seasonal rainfall, temperature and other agronomic variables between the prior years and the season described are not quantified or controlled for.
Claims about cattle sensing energy or grass being sweetened are the interviewee's own interpretations and are not mechanisms with established support in agricultural science.
Exact dates, location details and paddock or irrigation specifications are incomplete in the source.
