Tips to get accurate pH measurements

Even if you have the best device, there are chances of mistakes that may cause a difference in the truth value of the pH. If you are using these kits for the first then we suggest you follow the tips given below for measuring the accurate values.

  • Firstly you need to water your plant thoroughly. But make sure to check immediately after watering your plant so that there should be no change in the pH value due to water.
  • The test is always at room temperature. pH value is inversely proportional to the temperature so, the temperature may change the value of pH.
  • If exposed to extremely high or low temperatures, high humidity, or fluids, pH meters may lose their calibration. So, calibrate your pH meter.

What is the use of pH kits?

Before this, you need to know why you should know the pH level of the soil. We all know that soil can be naturally acidic or alkaline. The amount of nutrients and other substances that are soluble in soil water and hence accessible to plants depends on the pH of the soil.

While certain nutrients are more readily available in acidic environments, others are more readily available in alkaline environments. From this, you can get an idea about the use of pH kits. 

These kits are specially designed to check the pH conditions of the soil so that you can get an idea of which species of plants you can grow on that particular soil. If you talk about an ideal range of pH, would be around 6.5 to 7.5. 

Most of the macro and micro-nutrients are available in this range. But this is not the compulsion. These pH testing kits have a pH buffer solution that stabilizes the pH of the soil after it reaches its ideal level. 

Concluding lines 

All the test meters that we have mentioned above are the best ones. But if you are still confused about which one to use then we suggest you choose the AgoKud Soil PH Meter. You need to focus on three things before buying any meter that is measurement metrics, ease of use, and probe length. Read the whole guide for its proper understanding.
