- Water used for irrigation can affect the pH depending on its specific alkalinity/acidity
- Fertilizer selection. Logically, fertilizers can decrease/increase pH significantly
- Plants itself; in different growing stages, plants can also cause a reaction with soil and differences.
There are several reliable ways to approach the soil pH measurements.
Many agriculture producers rely on methods like dilution or slurry. These techniques can be accurate, but require a certain amount of time and expertise.
Direct method – the fastest and most reliable method
There are several options of meters on the market that measure soil pH directly and giving you an instant result. Technique is very simple, a probe is inserted directly into the soil or soilless media and results is shown on the screen instantly.
Add some distilled or deionized water to the hole; the soil should be damp but not saturated with water.
and allow for the reading to develop or stabilize.
Simple!
Each of our meters has a specifically designed probe for the application and specifications showing the resolution and accuracy.
