Best way to test ph in soil

Here is one way to check your soil ph with a probe.

You will need two items the ph meter probe and distilled water.

Distilled water has a neutral level ph so it will help when using the probe.

Mix at least 2 inches of depth in soil to create mulch, then wet the area with the water and then place the probe in and record the reading.

Do this in at least 3-4 parts around the plants base.

The average the results will give you the ph reading,

A second way is a professional test kit, with this you can check multiple levels with nutrients N-P-K or even ph levels.

Take samples of soil and add the required amount of solution type for the test required. Wait a set period until results appear.

How to test soil ph with ph water

There is another way to check ph level, and that is by examining the runoff of your plants after watering.

You can test with a digital probe or pen meter of your choice. 

This is done when watering with ph neutral water such as distilled water, you can also use reverse osmosis water or regular tap water. 

Just make sure you adjust your ph level of the water.

After the runoff occurs collect it in a container. Then check the ph level with digital ph reader.

How accurate are soil ph meters

Soil ph meters can give you an indication your soil is either in high medium normal or lower ranges.

It's best for you to take multiple test samples to get your average ph level.

If you are using checking your plants in pots, you can also check the runoff of your water to determine the ph level.

Some growers argue this is a far more superior way to test your ph level than using a probe to stick into the soil.
