Plant sap pH reflects the mineral balance within a crop. What is mineral balance? It is the idea that certain proportions of minerals within the plant reflect optimal plant health. For example, there may be too much of calcium or too little, too much of zinc and not enough copper, and so on. For example, If copper to zinc ratios are way out of balance in a human, serious consequences may likely follow if this imbalance persists .
Plants also may get affected by minerals since the minerals affect their growth and overall development. Too much or too little of virtually anything can be bad. If society has been able to grasp this conceptually, then why has almost nobody paid attention to this in relation to plant nutrition?
For example, NPK farming approaches are a great recipe for growing plants very susceptible to disease. How do I know the NPK approach fails miserably when it comes to providing optimal nutrition? The pH meter measuring out the sap of such plants will demonstrate serious imbalances. It provides an answer the question of which proportions of mineral indicate balanced plant nutrition.
High nutrition farming consultant Graeme Sait states: “Bruce Tainio has discovered that the pH of plant sap is another indicator of plant health and associated pest and disease pressure. An ideal sap pH of 6.4 reflects the optimum vibratory frequency for that plant. If plant sap is acidic, then the vibratory profile of that plant attracts disease. Conversely, if plant sap is alkaline, insects are attracted. There is a beautiful synergy in Bruce’s concept, in that the measurable number (the vibration that represents the state of balance, also reflected as a sap pH of 6.4) comprises the sum of the vibrations of all of the elements that determine the sap pH. That is, each element vibrates in a unique manner, and these vibrations can now be categorised numerically. If there is a deficiency in a cation – calcium, potassium and magnesium being the key players – then there will be more hydrogen in the plant sap, the sap will be acidic and the plant will attract disease. At the other end of the pH-spectrum, the anions are shaping the scenario. If the acidic anions – nitrates, phosphates and sulfates – are deficient, then the balance is blown. The sap pH becomes alkaline and it’s ‘tucker time’ for the sap-suckers. There is no incongruity here” .
Sait’s company Nutri-Tech is a big promoter of this tool of food quality. He adds “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 predisposition to ward dis ease. If a zucchini in the trial plots has powdery mildew, it’ll always have a sap pH be low 6.4″ . The insight from this quote is that the sap pH test also tells a grower what nutrition corrections they need to make if the number deviates from the ideal of 6.4.
Nutrition farming pioneer Bruce Tainio explains how he came up with plant sap pH as model of plant health:” What I concluded was that every element on the atomic chart has a Hertzian frequency – a natural vibratory frequency, and I have all of those frequencies, for each of the elements. 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 dis placed 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” .
Sait is one of a growing number of consultants who look at both brix and sap pH as indicators of nutrition levels and mineral balance. In practice, I have found that the plant sap pH gives a more accurate and specific indication of mineral imbalance than the refractometer. For example, I have one seasoned grower who has long since reached very high brix numbers on his crops but the plant sap pH had not been at 6.4. As he improved the sap pH, getting closer and closer to 6.4, he saw better and better results in the field.
Tainio has noted that plant sap pH also has a bearing on shelf life levels . Thus, this measure can predict shelf life. How much it can do so still remains to be seen. Farmers who do a good job with the Tainio protocol, which included monitoring and making nutrition corrections based on sap pH, whether foliar or soil amendments. do see signficantly better shelf life.
