What is the difference between a soil moisture tester and a soil water potential tester?

Soil moisture detector and soil water potential meter is now very widely used, in the usual sales process will also encounter customers ask the difference between these two instruments, today the small side of the collation of the following content, detailed that the difference between the two instruments, let us take a look.

The obvious difference between soil moisture detector and soil water potential meter is their functions. Although both are used for testing soil, they have very different functions. Let’s talk about the function of the soil water potential detector first. The function of this instrument is mainly to detect soil water potential. What is soil water potential? Soil water potential is the amount of energy required to extract a unit of water from the soil at isothermal conditions. The unit is bar. If the soil is saturated with water, the water potential is zero; if the water content is below saturation, the water potential is negative. The drier the soil, the greater the negative value. The general plant survival range is 0-15 bar. Soil water level measurement is not affected by various soil properties. The measurement results can be used directly for irrigation indicators, overcoming the disadvantages of different soil properties.

After understanding the soil water potential meter, let’s talk about the water velocity tester. As the name implies, the instrument detects the soil water content. Water is an important part of soil and plays a very important role in crop growth and water-saving irrigation. GPS positioning system grasps the distribution of soil moisture (water) and provides a scientific basis for differentiated water-saving irrigation, and accurate water supply also helps to improve crop yield and quality.

Soil moisture detector and soil water potential meter play an important role in practical applications. I also hope you can correctly choose the product you need through the above article. Only by choosing the right product can you perform better and increase your income.
