Soil pH is a measure of the acidity or alkalinity of the soil. Having the correct pH is important for healthy plant growth as it reflects the chemical conditions.

Soil pH – a Measure for Plant Health

Soil pH is a measure of the acidity or alkalinity of the soil. Having the correct pH is important for healthy plant growth as it reflects the chemical conditions. For example, the pH controls the availability of nutrients. The solubility of certain elements increases by lower pH levels, slowing down or stopping root growth. Also biological functions, microbial activity, and the behavior of chemicals is controlled by the pH levels. Knowing this, it is wise to check the soil pH frequently.

Healthy Soil pH – Important for Various Markets

As the soil pH has influence on the plant growth, the importance to check and adjust it is important for a lot of market segments. To name a few: crop growth for the feed market, hemp for the industrial and medical market, hay for the horse market and fruit trees like the blue berry for the food market. All of these are affected by a suboptimal soil pH and so checking and adjusting pH is of great importance.

How to Perform Soil pH Measurements

In soils, the pH is measured in a slurry of soil mixed with water. The LanceFET pH probe, thanks to its PEEK tip with stainless steel point, is perfectly suited for this piercing application. After predrilling a hole in the earth the more generally used ConeFET probe with a blunt tip of PEEK and ABS can also be used to measure the pH in the soil.
The positions of the ISFET and reference electrode have been designed to be clog and pollution resistant. In the event debris has accumulated on the sensor it can be easily cleaned with running tap/deionized water and soft toothbrush, which is of benefit for the probe’s performance and prolonged life.
