How to use the soil thermometer

You need to follow the steps to help you use the soil thermometer. This include:

  1. Choose the correct depth for measurement performance.
  2. Use a small tool, such as a screwdriver, to drill out the pilot hole. This hole will not damage the thermometer if you force it on hard soil.
  3. Then insert a thermometer in this hole and follow the instructions with the soil thermometer.
  4. When the sun is shining, shade the thermometer.
  5. Take the reading twice a day, then calculate the average of the two results.
  6. Finally, check the reading and then write it down for future reference.

Factors to consider when buying the soil thermometer


The soil thermometer comes in two types: analog and digital. The analog thermometer can give the temperature recently, but it is also suitable for a long time. Also, you don’t need to be exposed to moisture when using this thermometer.

In terms of reading accuracy, the digital soil thermometer is a priority. However, it requires some maintenance as soil moisture cause some problems and can affect it.

Construction material

When buying the soil thermometer, you need to consider the construction material. Analog and digital thermometers are the most common varieties.

Analog thermometers are waterproof, so you can leave them in the rain and then use them if you want. The digital thermometer is the ideal tool for the accurate reading possible.

Construction materials play an equally important role. A thermometer with plastic, stainless steel, or a mixture of these two is available in most grocery stores.

Typically, stainless steel models are recommended. Keep an eye on the tightly closed thermometers to avoid water from entering the thermometer.

Probe length

Shallow or deep, the thermometer should be put in the soil. In many thermometers, a tip is about 5 cm long. We need to use a thermometer with a long probe length to get reliable readings. So, you need to consider this factor when buying the best soil thermometer.

Temperature scale

The temperature scale becomes the crucial factor when getting the best soil thermometers. The thermometer should have a temperature scale that ranges between 35 and 75 degrees Fahrenheit.

Because it is necessary to measure the temperature of the soil at various times, the soil is supposed to have the temperature range in different locations, including germination point, seeding point, etc. Therefore, the temperature scale must be wide.


The soil thermometer dial should be fog proof so you can read the temperature at any time. It should be big enough for farmers or gardeners to read easily. Some of the thermometers have multi-colored dials. These can also be clearer and simpler.


A stem is an essential factor to consider when buying the best soil thermometer. For sowing, a short-stem thermometer is perfect. Consider using the long-handled thermometer to determine the root zone temperature.

At what time of the day should the soil temperature be measured?

It is recommended to take several measurements late in the afternoon and the morning. Then calculate the average of these two numbers. Essentially, if you plan to plant the grass, measure temperatures on all four sides of the yard. Some areas warm up faster than others.

What degree should the soil thermometer read before it is placed on the soil?

The soil thermometer may read any temperature. These tools read the surrounding temperature and can measure the temperature of the air.

How deep can the soil thermometer be in the soil?

The bottom of the ideal soil thermometer can record the temperature. Typically, you need to think about the type of seedlings you’re doing. If you like seeds, slowly dig the thermometer into the soil. Your goal is to measure the plant’s root zone temperature, so be sure to dip the thermometer as deep into the soil as the seeds.

Between classic and modern soil thermometers, which is better?

A classic thermometer is fine if you stick with the simple garden with just some crops in a row. Likewise, consider a modern soil thermometer if your goal is to be a bit technical and versatile in the garden, and you need to be a 24/7 gardener.

What are the valuables you can use to check soil temperature?

Various variables emerge from basic soil testing. Target variables in the tests include pH levels and macronutrients such as phosphorus, potassium, and nitrogen. Also, remember the level of organic matter.

The basic soil test just provides information on the general soil properties. These tests do not detect pesticides, pollutants, or other toxic compounds.

To check the soil temperature does not require planting all vegetables and fruits at a specific time of year if it is not necessary. Some plants thrive in cold temperatures while others thrive in warm.

How can you control the soil temperature?

In cold climates, soil can be kept warm by covering it with an organic matter known as mulch and draining the soil. The mulch keeps the land surface cool even in the hot summer period.

Organic matter mulch increases the water absorption in the soil. This keeps the soil moist and takes longer to heat up in the summer and cool down in the winter. Also, the light-colored organic matter reflects some of the incoming solar radiation on the Earth’s surface.

The land surface can be covered with dark plastic mulch that absorb the incoming solar radiation, reducing water evaporation from the soil and preventing the land from radiating heat. Thus, the soil can be kept warm by covering it with a dark plastic mulch in winter.

What type of soil thermometer is best?

Some thermometers are better suited to farmers and gardeners than others, and this depends on the features and conditions. If the soil thermometer has the best features to meet your needs, that is the best.

What is the ideal soil temperature for most seeds to germinate?

Most seeds germinate once the soil temperature is 68-86°F. When germination has occurred, the ideal growing temperature is about 10°F cooler than the optimal germination temperature. Typically, moisture is essential for seed germination.

How does the temperature affect the decomposition rate?

When the temperatures are colder, decomposition organisms are less active. The degradation rate remains to be low. Once again, a very high temperature will kill the decomposers and stop the decomposition.


The soil thermometer can now be judged by what it can do. So, you can plant your garden, but first, use the soil thermometer to determine the soil temperature.
