What’s a Moisture Meter?
Having the correct information about soil moisture is essential for healthy plants. Sometimes it can be difficult to guess the exact need of certain plants and that’s where the moisture meter comes into play.
A moisture meter or sensor is a tool that measures the humidity or moisture of the soil. Usually, it works by measuring the electrical conductivity of the soil and thus give the information you need.
Experienced gardeners know that most plants don’t thrive in a moist environment because wet soil can hinder healthy root development and cause them to rot-no one wants this to happen.
Therefore, a device like this can help avoid overwatering and understand when’s the right watering time.
Different types of soil can hold different amounts of water, thus if you work with different soils in your garden this device will come in handy.
Moreover, they can be quite useful for composting since the level of moisture is essential to improve the growth of microbes and the probe can estimate the wetness level in a matter of minutes.
Why’s it Important to Measure Soil Moisture?
When we talk about soil moisture, we usually refer to the level of wetness the soil has i.e. the amount of water it contains.
The moisture of the soil is vital in various biological, hydrological and biogeochemical processes and having precise information is valuable when it comes to healthy development and growth.
Soil moisture can influence:
- the number of food nutrients the plants receive
- the optimized watering process can result in a better yield and healthier plants
- regulates soil temperature that can influence different chemical processes
- influences metabolic processes of microorganisms
- the base component of the plant is water
- photosynthesis can’t happen without water
What Types of Moisture Meters Are There?
There are different types of moisture meters however, the average homeowner needs something simple, user-friendly and precise. So just a basic moisture meter will do the job.
To give you a better understanding of all the different types we present you with a short overview below:
This type of moisture meter doesn’t require batteries and has a basic design. Despite the basic design, these units are quite effective and precise.
They measure the naturally occurring electrical conductivity of the soil and the probes are made of conductive materials that register any water presence in the soil.
Unlike the analog meter, a digital one has more advanced features. They use batteries to power the screen and also create an electromagnetic pulse that can detect moisture.
Often, the probes are connected to cables and not directly to the device.
These are more dated types of moisture meters that are quite popular for indoor container plants. The device usually absorbs moisture which travels up the fabric that changes its color if it registers moisture.
The hybrid meters are popular among gardeners and probably offer the best value for money. They can read multiple conditions such as sunlight level or pH value. They can’t be as accurate as a specific moisture meter but can help out with your gardening activities.
How to Read Moisture Sensors?
Most of the moisture meters are easy to read however, this may vary depending on the type that you use.
For example, a digital model comes with a user-friendly screen and the analog ones have dyed characters that denote the condition of the soil as wet, moist or dry.
Further, as the name implies the wicking model has a fabric band that can change the color when the soil is wet.
What are the Benefits of Using Moisture Meters?
Using a soil moisture meter can provide many benefits and one of the primary ones is understanding the life of your plant and carefully planning its care.
An inappropriate watering routine can be the reason for plant damage and even death. In most cases, too much water can cause the plant’s root to rot –hence, the roots aren’t capable of getting the needed nutrients and the plant will wither.
On the other hand, overwatering can also cause similar problems that might result in your plant withering and dying.
Besides plant health, a simple moisture meter can help you save water, especially when watering your outdoor plants. By checking the moisture level, you can be certain of the amount of water your plants require and thus save more.
Lowering water utilization can help you save money and save your plants.
What to Look for in a Soil Moisture Meter?
Choosing the right soil meter depends on what you need it for. If you’re planning to use it for your houseplants, then go for one with a shorter probe which is a less expensive option.
Nonetheless, if you need the moisture meter to be used outside you’ll need a sturdier option with a long probe and this is especially important if you’re working with hard clay-like soil.
