What to Look for When Picking the Best PH Meter for Gardening
Ease of Use
When it comes to gardening, it wouldn’t matter if you have a doctorate in chemistry or not. Soil pH meter kits should be easy to use and gardeners should prefer those gizmos that provide easy to read outputs.
On the other hand, chemical dye kits can be a lot trickier to use, especially for people who don’t have any experience with chemistry. Probe style meters are, therefore, the safest investment because they only require users to stick the probe into a diluted soil sample or the ground.
Accuracy
Accuracy is a very important consideration and typically, chemical dye kits don’t return a specific value for output but they never fail in terms of accuracy. To ensure your probe meter is outputting accurate results, you can try to take the same reading a couple of times and then settle for the average.
Additionally, you can also take a soil sample from your garden and mail it over to the local lab so you can compare your probe meter’s pH output with their readings. This is a quick way of assessing how accurate your instrument really is.
Probe Depth
The golden rule for using pH probe meters is to measure the pH of plants at root level. However, the actual depth will vary according to the plants in your garden by anywhere between 2 to 10 inches.
Long probes tend to offer more versatility than shorter ones because they can be set at different depths, Alternatively, you can also use extra soil samples from any depth to take a reading without worrying about the meter’s length.
Range
All soil pH meters aren’t created equally and analog probe meters typically measure pH between the 3 to 8 range. This can be a sufficient feature for mature plants but seedlings and younger buds might require a little more control. This is where digital meters will be a better choice.
Digital pH meters are oftentimes developed for plant germination and they cover the plant’s entire pH spectrum ranging from 1 to 14. Similarly, chemical dye tests also provide very accurate results from all over the pH range.
Our Final Thoughts
In order to make sure that your beloved plants develop to their full potential, gardeners need to be able to measure pH levels properly. If, for instance, they notice that the leaves in their garden are turning yellow or are displaying other anomalies, then a good place to start troubleshooting would be to measure the soil’s pH level.
It is very important to buy and use the best pH meter for gardening purposes because they deliver the most accurate readings, especially if you’re trying to neutralize your soil’s pH level.
