What Is Soil Thermometer And How To Measure Its Temperature

Measuring temperature of the soil in a vegetable garden using soil thermometer

You might have heard of the term soil thermometer and you are wondering what it is all about or probably what it is used for. In this article, we want to take a closer look at what soil is and how one can know or measure its temperature. Before going into full details about the soil we want you to know we accept guest posts here on our website. In case you have similar or related articles that can help our readers you can also write for us.

Importance of Soil Thermometer

Agriculture in any form makes use of soil, it is a very important component for plant growth. Farming has almost taken over the world and has its one of the largest main sources of wealth in different countries. Some countries are dependent on their farm produce for the sustenance of their economy because it’s one of their strength of exportation. But before all this can be accomplished, good soil is needed for proper plant growth. To ensure your soil is good enough for planting, various tools can be used which soil thermometer is one of them. Before we go into soil thermometer as a tool, we will need to have a better understanding of soil.

Soil consists of organic matter and inorganic particles which provides structural support and also serves as nutrients and water source for agricultural plants. The inorganic particles are formed from rock weathering. It’s a process(chemical/ mechanical) where rocks are broken into pieces. The components of soil make it one of the most important natural resources of the earth. The definition of soil can be many as people used it for different purposes and occupations and are known to be limited natural resources. Soil is complex as it has various purposes it serves to individuals.

How It Is Useful For Farmers

For farmers, it is used for planting, soil structure particles need to be studied farmers to know the appropriate soil to grow plants. Engineers, need to understand the type of soil that can hold up a building structure. The ecosystem also is not left out, as it’s needed for sustainability for vegetation growth. Soil is categorized mainly into three groups or types which are the clay, sand, and silt. The different types of soil vary in their composition and structure which is why farmers always look for rich soil for healthier plants.

With the help of a soil mixing machine or soil mixer farmers can mix different types of soil or even mix fertilizer with soil that lacks the essential nutrient for plant growth. Color, structure, and texture are what make soil to be soil being the important component of soil morphology. Soil level meaning can refer to the various level you can see when you dig a hole that can show the vertical section of soil. The level can be from the surface of the soil to the underlying particles.

Soil Thermometer And Its Use

A soil thermometer is designed specifically for the measurement of soil temperature. A soil thermometer is a very useful tool for farmers, gardeners, soil scientists, and climate scientists. When it comes to making planting decisions for both farmers and gardeners, the soil temperature is vital. As it helps them to know the readiness of the soil for planting. If planting is done with the wrong soil temperature, this may not yield effectively as it supposes to. Guidelines like the season, air temperature, etc might be put to use. But if the temperature of the soil is not monitored, it will all amount to nothing.

Soil Thermometer Described

To test the temperature of the soil, there has to be a part of the instrument that should be deepened into the soil. This instrument has a probe as part of its component, and this part is deep into the soil. Not all the parts will enter the soil, some parts of it will be left out to read the measurement. A mercury bulb thermometer is used for the measurement.

This bulb thermometer is of two types, traditional and digital/analog. The digital type helps to read the soil temperature fast and easily. The probe should be well maintained as it can easily get corroded. Make sure it’s thoroughly wiped from sand or possible salt especially when it’s used in a wet environment to avoid corrosion. Almost all soil thermometers have a cover case for protection

For reading, some soil thermometers require that after inserting into the soil. It should be left for a while before reading for accuracy. Some read temperature immediately and this can be used if a soil condition wants to be checked quickly. Others are designed to be left in a greenhouse or an environment that can be controlled.

Before buying a soil thermometer, make sure you check for its highest temperature limits. For example, if a compost pile wants to be checked, the temperature of this type of soil might be too high for a soil temperature. So, It is required that you do a thorough check on the type of soil thermometer you want to buy.


Soil’s definition is dependent on its function to an individual or one’s field of work. As its definition is different for an engineer, it is also different for a farmer, so also an ecosystem. But a general definition has been given to it which is the composition of organic and inorganic matter. To determine a soil’s temperature, a soil thermometer is used.

You need to understand that to make use of a soil thermometer; you need to know how to read it, and its management. How to get the exact one you need as its temperature varies. We also need to know how it works and how it should be used. It is also mentioned in this article that there are different types of soil thermometers.
