What Is A Moisture Meter And How Does It Work?

A moisture meter is an instrument used to measure the amount of water in the soil. It consists mainly of a metal probe that is inserted into the ground and connected by cable to an electronic readout device.

The meter’s probe contains an electrical resistance sensor, usually consisting of two dissimilar electrodes, that measures soil moisture levels by measuring the electrical resistance of the soil between a pair or a small group of electrodes.

Why Is Measuring Soil Moisture Important?

Soil acts as an enormous underground reservoir, capturing and storing water during periods of rainfall to use as a resource for plants growing above ground. Measuring the amount of moisture in the soil allows you to carefully monitor its availability during dry periods and ensure your plants have ample water.

Precise measurements of soil moisture levels allow you to know when it is time to irrigate or give your plants a drink, as well as how much water they need. This can result in reduced irrigation needs, increased yields, increased plant growth, and earlier flowering.

What Is the Distinction Between a Soil Moisture Meter and Rain Gauges, and Which One Should You Use?

There are two different types of devices used to measure soil moisture: electrical resistance meters and optical sensors. Both instruments use probes to determine soil moisture directly through touch with the root zone.

They also deliver this information to electronic controllers which can automatically provide the right amount of water as needed. Optical sensors use an infrared beam to measure moisture levels, while resistance meters monitor soil’s ability to conduct electricity and require you to read a gauge or digital display.

Rain gauges contain a funnel that collects rainfall from the atmosphere, while soil moisture meters are used to measure the amount of moisture already in the soil. A rain gauge is not designed to get wet; it should be placed on something like a piece of wood or even stacked bricks at least 3 inches off the ground. The wetness sensor feels like a pen and goes deep into the ground for an accurate reading of the moisture level.

Advantages of Using a Soil Moisture Meter

The short answer is yes! Not only will a soil moisture meter save water and money, but it can improve plant production and reduce labor costs. A professional-grade soil moisture sensor costs less than $100 and can pay for itself within one growing season. Here are just some of the benefits you’ll get from owning a moisture meter:

– Accurate readings of the amount of water in the soil, helping you make water a precious resource and not waste it or lose it to evaporation. You’ll get rid of that hose which can waste up to 1/3 of your water bill.

– Measurements taken every day will allow you to be proactive in taking care of your garden. No more and no less water than is required

– The ability to set minimum and maximum moisture levels for your soil, which will allow you to avoid the stress of drought or overwatering. You can save up to 30% on fertilizer costs by knowing how much water your plants are getting.

– More even growth across all areas of the garden since you’ll have an up-to-date understanding of what your soil is doing at any given time. This will allow you to maximize the health benefits of the fruits and vegetables that end up on your dinner plate.

Types Of Soil Moisture Meters

These devices are most effective when they’re used every day. Daily soil readings will allow you to make minor adjustments in the amount of water given to your plants which, over time, will provide them with exactly what they need. Not giving enough or too much water can cause your plants to either mature slower and produce smaller fruit, or to wilt and die.

Carefully calibrate your soil moisture meter before you start using it to get the most accurate readings possible. Make sure that the probe is inserted far enough into the ground – up to 3 inches – so that it can make contact with the roots of your plant.

They are available at most gardening centers or hardware stores. These tools can come in digital, analog, and hybrid forms. Digital models are very easy to use and they don’t require calibration, but analog meters can be more accurate because of their physical needles or dial face. Hybrid models provide quick feedback on how much water your plant needs, but their readings aren’t as accurate as those provided by other types of soil moisture meters.

Analog Soil Moisture Meter

Analog meters provide a physical needle or dial that allows you to determine how much water is in the soil. These meters are very easy to use and can be very accurate, too. Most analog models come with a test kit so you can adjust their calibration based on your soil’s needs.

Digital Soil Moisture Meter

Digital meters feature a printout or digital readout of the current moisture level in the soil. These meters are very easy to use, but they should be used in conjunction with a soil probe for accurate readings. Analog models have been known to give false readings when pushed too far into the ground; however, most digital devices don’t experience this problem.

Wicking Moisture Meter

The wicking method is a common way to determine the moisture level in the soil. It’s done by using a drying agent, such as calcium chloride or silica gel, and observing how it changes over time. This approach is cheap, and its readings are comparable to those obtained using other techniques. However, these meters aren’t capable of taking long-term moisture levels into account.

Hybrids Soil Moisture Meter

Hybrid meters use both the wicking and conductivity methods to determine soil moisture. These models are equipped with a probe that must be inserted into the ground to gather data about the water levels in the soil. Hybrids can give you immediate feedback on how much water your plants need, but they’re not capable of storing previous readings like other types of soil moisture meters.

How To Use A Moisture Meter

When a plant needs water, its leaves will wilt and eventually turn a darker color. This is because the soil loses its ability to hold onto moisture as it dries out. A simple way of determining whether or not your plants have enough water is by monitoring their appearance on a daily basis.

However, there are a few drawbacks to this technique. First off, you can’t always rely on other people to tell you if your plants need water because every gardener has a different standard for what they consider “thirsty.” Excessively moist soil may also cause leaves to drop off. Waterlogged soil is an indication that too much or not enough water is available.

A soil moisture meter will provide an accurate reading of the current moisture level in the soil in the plant’s root zone. By taking a reading every day, you’ll be able to make small adjustments in the amount of water given out which will provide your plants with exactly what they need over an extended period of time.

Insert the probe into the earth with a soil moisture meter. If you’re using an electronic device, it should beep or display a temperature reading once it’s touching moist soil. Keep in mind that the probe needs to touch all sides of your plant’s root zone so don’t push it too far and damage its roots and bulbs. 

Once the meter is touching moist soil, take note of the reading. After doing this for a few days, you’ll notice that there are small changes in those readings as the soil gets wetter and drier. Follow those changes and determine whether or not your plant needs water based on how dry it’s become since your last reading.

If the meter displays a low reading, then chances are the soil is too dry and you need to add some water. You may also examine your plants after they’ve been watered with them. The readings should begin going back up as soon as the moisture from the added water sinks in .

What to Look for When Shopping for The Best Soil Moisture Meters

Is It Appropriate for Indoor or Outdoor Usage?

Indoor and outdoor models work in the same way, but their probes and exterior design are not made to withstand harsh weather conditions. This means that an indoor meter will probably break when used outdoors, so you’ll want to check its specifications before buying it.

Analog vs. Digital

Digital meters are easier to use because you don’t have to interpret the readings on an analog meter. Digital models are also capable of storing previous readings for easy reference. However, these characteristics may increase the price of a product.

Ease of Use

Be sure to get a moisture meter that’s easy to use and accurate. These two factors will decide whether or not you can get precise readings from your device, which is important for making adjustments in the way you care for your plants.

Soil Type and Texture

A meter’s capability to measure moisture levels in various soils and textures will depend on its calibration system. Some soil moisture meters can be calibrated for use with specific types of soil or plants so it’s important to check the specifications before buying one.

Measurements

Water meters are available in measures of 0 to 10, 0 to 20, and 0 to 100 units. A larger scale will make it easier for you to determine the moisture level at a glance, but these models can be more expensive than those with smaller scales.

Price

Since these meters are considered inexpensive gardening tools, their price shouldn’t be a major factor in your decision. However, it’s still important to consider the price tag of the different models before buying one since they come in a wide range.

Accuracy

Make sure that you read reviews and check the specifications of a meter before buying it since these factors will determine how accurate it is. The more accurate your soil moisture meter is, the better readings you’ll get which will allow you to properly provide water for your plants.

Scope Length

The scope is the probe of a meter, and its length can affect how precise your readings are. If you’re growing large plants, then it might be better to get an extended-reach model since it will give you more accurate readings.

Power Source

When shopping for a soil moisture meter, you’ll also want to research the different models available in terms of their power source. Some meters are powered by electricity while others can be manually powered by batteries and still, others use solar energy.

Display

Moisture meters, like many other gardening tools, come with LCD displays. There are also models that use LED lights which can be more expensive but more reliable for reading moisture levels since they don’t need to be charged.

Some models will only read the dryness of the soil while others can calculate a plant’s water needs. If you have a tiny yard or container plant, be sure to read the specifications of a meter before purchasing one.

You should also keep in mind that some models are best used by professionals so be sure to do your research before buying one.

If you’ve been having problems caring for your houseplants, then checking the soil moisture level is a step that shouldn’t be overlooked since it can help you determine how much water your plants are getting. A soil moisture meter will also save you time and effort, so check out the different models available before deciding which one to buy.
