Graeme: I’d like to ask you some questions about your sap pH technique. One of the reasons that we travelled all the way to Spokane from Queensland in Australia was because I consider this finding of yours to be a major breakthrough. Our research department has been working with the sap pH concept for the past twelve months and we’ve yet to find an exception to your rule that acidic sap creates a pre-disposition toward disease. If a zucchini in the trial plots has powdery mildew, it’ll always have a sap pH below 6.4. We promote your concept on a wide scale in Australia.

Bruce: Because all cells in all living organisms have an ideal level of each of these elements, there had to be a relationship between the vibratory frequency and the pH of the plant sap because the presence or absence of these elements determines pH. When we found the link, it covered my rear to a certain extent because I was able to get away from talking vibratory frequency and begin talking pH, which everyone was familiar with. It’s not a big step to move from soil pH to plant pH as a valid analysis tool. In essence, I discovered that there was a direct correlation between the hydrogen content in the cell and plant health. At the ideal of 6.4, the hydrogen content of plant fluids is approximately 12%. If you calculate out all of the frequencies attributed to each element - add up their individual frequencies - you’ll come to the ideal frequency of a living plant. If there is more than 12% hydrogen and the plant sap is acidic, it will mean that you have displaced one of those elements and usually it turns out to be calcium or potassium. This displacement alters the vibratory frequency of that plant. So this is how I got into the pH concept in the first place.

this sounds like a couple forum members rolled up into one.

somebody posted a link to a ph pen that could measure both plant sap and solution mix.

the dj forum has a bunch of new age stuff.

i am really interested in the tools used by proper plant scientists to get to the 'next level' of growing. sap ph, brix levels, soil saturation ratios, specific NPK values and understanding the relationship they have with genetic expression in different enviroments... whole lot of shit to understand.

Plant Tissue pH = Energy
By Bruce Tainio

While laboratory soil and tissue tests are good and necessary tools, we often don’t receive the results for several days, or even up to two weeks in some cases. On a growing crop, that can be too late. With this in mind, we developed a diagnosis of plant health based on liquid pH values of plant tissue sap, which has been used in our biological program at Tainio Technology & Technique since 1989.

Simple to use and 100 percent accurate, a quick plant tissue pH test is an instant snapshot of the state of health of any plant and can tell us the following information:

1. Enzymatic breakdown of carbohydrates (sugars) for proper growth and vitality of the plant.
2. Risk potential for insect damage.
3. Risk potential for foliage disease attack.
4. Nutritional balance in the growing crop.
5. Quality of nutrition in the fresh fruit or vegetable crop to be harvested.
6. Shelf storage potential of fresh fruits and vegetables.

The table below is a general guideline to determine what tissue pH means. With this scale we can predict the probability of insect and disease resistance or susceptibility.



The dictionary defines pH as “a number equal to the logarithm of the reciprocal of hydrogen ion concentration within a solution.” That’s a mouthful, but more simply put, pH represents the percentage of hydrogen ions in a solution. In our case, the solution is the liquid of the plant cell, or the sap.

It is important to know that a change in the pH level of a solution of just one unit equals a tenfold change in the hydrogen ion concentration. If the pH is increased or decreased by two units, the hydrogen ion concentration changes by a hundredfold! Thus we can see why what appears to be only a slight shift in pH can spell disaster for the farmer.

A neutral pH of 7 within the cell fluid means it contains 100 percent saturation of cations other than hydrogen (in other words, the sap contains no free hydrogen ions). At a plant’s ideal cellular fluid pH of 6.4, the saturation of cations other than hydrogen is about 88 percent. At 88 percent saturation – principally of calcium, magnesium, potassium and sodium – the ionization and activity of these elements generates an electrical frequency of between 7.5 and 32 Hertz, which is one of the “healthy” frequency ranges of all living cells.

To decrease cellular pH to 6.0 is to lower the saturation of the above four principle elements to 80 percent, thus lowering the plant’s frequency to a level of lower resistance to bacterial, fungal and viral plant pathogens.

Studies have shown that insects are attracted to a tree or plant by the tree or plant’s frequency. If the saturation of Ca, Mg, K and Na increases to over 88 percent saturation, the frequency from these ions in the cell are increased, and consequently, insects are attracted to the higher-than-normal cell frequency.

The same process occurs in animal and human cells. Hydrogen accumulation in the cell tissue means the saturation of Ca, Mg, K and Na is decreasing, thus causing the frequency to decline. This low frequency leaves the cell an easy target for disease.

Oftentimes we see both insect and disease problems occurring at the same time. This can happen when insects attack due to a high plant tissue pH, and the tissue becomes weakened in the localized areas of attack. Next, localized, rapid energy loss (a drop in pH) occurs at the insect-damaged spots, resulting in tissue disease attack of those areas on the plant.

When a pH shift of a half point (0.5) or more from the ideal 6.4 occurs in the cellular liquid, a laboratory tissue test should be taken to determine exact imbalances and which materials should be applied.

Tissue pH Rule of Thumb
Low pH + Moderate Brix = Calcium Deficiency
Low pH + Low Brix = Potassium Deficiency
6.4 pH + High Brix = Balance

In the interim, for a quick adjustment to bring up the pH, calcium can be foliar applied in small amounts per acre. To quickly bring down a pH that is too high, on the other hand, small amounts of phosphate can be applied to the foliage. These types of quick fixes are usually only temporary, however, and should only be used while awaiting a complete tissue test analysis.

Like most busy people, we have neither the time nor the patience to puree the two pounds of plant tissue it takes to get enough for a conventional pH meter readings; so we use the Cardy Twin drop pH tester, made by Horiba. With this pH meter, a reading can be taken out in the field in less than one minute. We just take a few leaves, roll them up into a tight ball, and squeeze out a few drops of sap using a garlic press. Be sure and use a good quality stainless-steel press, as a cheaply made garlic press will break.

Generally, the more mature leaves on the plant will give the most accurate picture of the plant’s health, level of resistance or susceptibility to problems. Since the plant spends most of its energy supporting new growth, the pH of new leaves will not reflect the pH of the rest of the plant as a whole.

pH & SUGAR

An indirect method of determining the energy levels of a plant is to measure the carbohydrate (sugar) levels in the cell liquid. For this test, a refractometer is used to determine the level of sucrose in the cellular fluid. This reading is referred to as the brix scale.

Within a given species of plant, the crop with the higher refractive index will have a higher sugar content, a higher mineral content, a higher protein content and a greater density. This adds up to sweeter-tasting, more nutritious food with a lower nitrate and water content and better storage characteristics. Such produce will generate more alcohol from fermented sugars and be more resistant to insects, reducing the need for insecticides. Crops with higher sugar contents will also have a lower freezing point and therefore be less prone to frost damage. Soil fertility needs can also be ascertained from this reading.

The brix levels should not be taken as an exact measurement of a plant’s vitality, but rather as a guideline. Stored sugar is not a cellular energy source until its carbon-hydrogen-oxygen molecular links are enzymatically broken apart. If this line breaks or energy release occurs faster than the cell can use it, then that energy is lost into the air. This condition usually occurs when the liquid pH of the cell is below 6.4 and most often indicates low Ca and high K.

The reverse can also occur – if the links between the carbon, hydrogen and oxygen molecules of a sugar are broken too slowly due to low enzyme activity, the plant becomes starved for the energy it needs for growth. This is usually caused by low manganese or zinc, or from high nitrogen/high tissue pH levels, coupled with drought stress.

As a general rule, we can say that when a plant has a low tissue pH and a moderate brix level, there is usually a calcium deficiency involved. On the other hand, a low pH with a low brix level usually indicates a potassium deficiency. The ultimate goal is to achieve a pH of 6.4 with a high brix level.

Plant tissue pH management is a relatively small but invaluable investment of your time and budget, which cannot only help you prevent disease or insect attacks, it can stop them in their tracks even once they have gotten started. This means better yields, bigger profits and most importantly, less need for chemicals.

Thanks C-ray u got me on the Brix and now pH of sap -

Very good read !

Sounded a bit kooky with "vibratory frequency"..
vibratory frequency of what?
I guess he was happy to move away form that phrase of speech, odd assuming he coined it..
At any rate, interesting stuff, thanks for sharing.

Edit: nevermind that's why it's good to read the whole thing before commenting, he was referring to the elements themselves(what I guessed).Double edit: electrical frequency.hmm.

"At the ideal of 6.4, the hydrogen content of plant fluids is approximately 12%. If you calculate out all of the frequencies attributed to each element - add up their individual frequencies - you’ll come to the ideal frequency of a living plant."

Oh rearry??

Am I the only one around here that thinks using a pH meter in organics is simply insanity?
