How to choose the best soil thermometer?

Let us share with you some factors that you can count on while shopping for your new soil thermometer.

Probe length

We know this might sound obvious but probe length is that one factor you wouldn’t want to overlook. Primarily, it decides the extent to which the tip of the thermometer can be inserted into the soil. For instance, if your soil thermometer has a smaller probe length, it’d not be able to measure the soil’s temperature and this affects the precision to the maximum. These days you can find thermometers that have at least 2 inches tip and a more elongated body so that you can know what’s going on down there.

Let us tell you that this one feature becomes more important when we talk about farming on a higher level. On the other hand, if you want one for your daily planting session, any regular probe length would work well.

Temperature range

We’d strongly suggest you first examine the temperature range of your soil thermometer before purchasing it. This is substantial since you don’t want any regular 0 to 180-degree temperature range when you are into professional farming and planting. In such cases, thermometers like Acurite soil thermometer work better since they can reach up to 220 degrees Fahrenheit which is an ideal value. On top of everything, let us tell you what matters the most is that you should know the right usage and the optimum timing that is required for the perfect germination of the seeds.

For instance, 40 degrees F that works for the radishes and spinach seeds might not work for the vegetables like onion and turnip. This is how basic information like this which has been derived by innumerable botanist associates program after years of hard work manages to go a long way.

Type of soil thermometer

Now, this is an interesting factor and depends mostly on one’s personal preference. You can go with either a digital or analog soil thermometer, both work fine under relevant circumstances. If we talk about digital thermometers, they might tell the exact temperature of soil without having you strain your eyes, but they are less resistant. This is why they are a better choice, especially for indoor planting sessions. However, the analog thermometers might seem confusing for their old scale designing but they are more resistant and can fight corrosion for a longer time. This makes them more suitable for higher grade farming and extreme weather conditions as well.

Coming to the composition material, you can find plastic soil thermometers as well, they cost less and go a long way under normal weather. Likewise, stainless steel thermometers tend to be more weather-friendly as they have greater longevity.

Temperature guidelines for the germination of different seeds

Apart from the reviews of the chart-topping products, we have come up with some of the essential temperature guidelines that might come in handy for the germination periods. Let’s start with the lowest i.e. 40 degrees Fahrenheit. At such a low temperature, you can go for the vegetables like peas, lettuce, and spinach.

Similarly, increasing the temperature by 10 degrees i.e., 50 degrees Fahrenheit would make a perfect home for onion, orchards, and turnips. For the bean lovers, you might have to take it a little higher and make it 60 degrees Fahrenheit to plant one of your favorite beans and vegetables like beet, cabbage, and carrots.

Lastly, with a temperature as high as 70 degrees Fahrenheit, you can opt for tomatoes, melons, and cucumbers, etc. Hence, all this basic know-how can help you a lot on your journey to a more fruitful planting season.
