Monitoring Soil Moisture Using Moisture Meters for Greenhouse and Nursery Management

Any seasoned farmer or gardener will tell you that effective irrigation management is crucial for the growth of plants. Accurately tracking moisture of the soil levels is even more important when growing plants in a greenhouse or nursery with a controlled climate. Under-watering can stifle growth and lower crop yields, while over-watering can cause plant stress, illness, and even death. Growers want a precise method of measuring soil moisture levels so that plants receive the proper quantity of water. The moisture meter is one instrument that has shown to be quite useful in this situation.


Simple portable instruments called moisture meters are used to assess the moisture content of soil. They operate by passing an electrical current through the soil and gauging the resistance. Resistance falls when water content rises and vice versa. The moisture level measurement is then calculated from the resistance value and shown on the meter’s screen.

Moisture soil meters exist in a variety of styles and configurations, but they all have the same fundamental function. There are several popular varieties of moisture meters, including:

  • Penetrometer-style meters:These meters monitor moisture of the soil at various depths by inserting a probe into the soil.
  • Tensiometer-style meters:These instruments gauge soil moisture by keeping an eye on the water’s tension within the ground.
  • Capacitance-style meters:These meters gauge moisture of the soil using electromagnetic technology.

Grower shall decide

The decision will rely on the demands and preferences of the grower. Each type of meter has benefits and drawbacks. Penetrometer-style meters may be used to measure the moisture content of soil at various depths, which is important for figuring out how much water the soil can contain. They help keep track of root growth and soil compaction. The probes can get damaged over time and take a little more work to operate.

tensiometer-style meters

Tensiometer-style meters are the best option for detecting soil moisture in the root zone. They employ a water-filled tube attached to a porous ceramic cup buried in the ground. Tension in the tube rises as the moisture of the soil levels drop, and the meter reads the change. Tensiometers are a great tool for determining the moisture content in pots, raised beds, or other non-waterlogged locations.

Most common

The most common kind of moisture meters are those in the capacitance style. They can deliver precise readings in seconds, are reasonably priced, and are simple to use. They monitor the moisture of the soil levels and those in other growth mediums like coco coir or peat moss using electromagnetic waves to assess the soil’s moisture.

They are essential for managing greenhouses

Moisture meters are a crucial piece of equipment for managing greenhouses and nurseries. By giving precise measurements of soil moisture levels, they assist producers in preventing either overwatering or underwatering plants. This knowledge is essential for modifying watering schedules and avoiding stress, illness, and plant mortality.

Overwatering can result in root rot and other fungi diseases, while underwatering can result in wilting and leaf loss. The soil’s moisture can impact how well a plant absorbs nutrients. While too dry soil might make it difficult for plants to absorb the essential nutrients, excessively damp soil can inhibit nutrient absorption.

Finding where water is wasted

Additionally, moisture meters can assist producers in streamlining their irrigation systems to conserve water and cut expenses. Growers can detect locations where water is wasted and modify their irrigation systems by routinely monitoring soil moisture levels. Water, fertilizer, and energy costs may all be greatly reduced as a result.


Numerous greenhouse and nursery businesses have automated irrigation systems managed by sensors that gauge the moisture content of the soil. These systems may be set up to only water plants when needed, helping to conserve water and lowering the chance of overwatering. Growers may further fine-tune their irrigation systems by combining them with moisture meters, ensuring that plants always receive the ideal quantity of water.

pinpoint growth space drainage

Determining growth space drainage issues is another advantage of employing moisture meters in greenhouse and nursery management. Drainage problems may be indicated by places where water collects often or by excessive soil moisture levels. Growers may take action to enhance drainage by locating these problem locations, which can stop root rot and other problems brought on by excessively damp soil.

maximizing the use of fertilizer

Additionally, moisture meters can aid gardeners in maximizing the use of fertilizer. More soil moisture can prevent plants from accessing nutrients, resulting in shortages. On the other hand, excessive moisture in the soil can cause nutrients to seep out of the soil and waste fertilizer. Growers may maximize nutrient absorption and minimize waste by monitoring soil moisture levels and ensuring fertilizers are administered when the soil is at the proper moisture level.

educated choices on the kind of plants to cultivate

Finally, moisture meters assist producers in making educated choices on the kind of plants to cultivate and the best locations for them. Moisture meters may assist producers in choosing the plants best suited for a given section of the greenhouse or nursery since different plant species have varied water requirements. By monitoring the soil moisture levels, growers can discover microclimates in the growing area that may affect plant growth and development.

To sum up

Moisture meters are a crucial management tool for nurseries and greenhouses. They assist producers in identifying drainage problems, maximizing irrigation systems, avoiding overwatering or underwatering plants, and fine-tuning fertilizer use. Growers should select the moisture meter that best meets their needs and tastes from various varieties and features available. Growers can guarantee that their plants always receive the right quantity of water by routinely checking the soil’s moisture levels, which will result in healthier plants, greater agricultural yields, and cheaper expenses.

Considerations when choosing

Growers should search for a moisture meter that is simple to use, reliable, and accurate when buying one. The meter’s display, which should be simple to read; its probe length, which should be long enough to reach the root zone; and its accuracy, which should be within +/- 5% of the real moisture content, are some factors to consider. To measure changes in soil moisture over time and spot patterns, growers should also consider investing in a moisture meter with data-logging capabilities.

Maximize the profit

Moisture meters are a crucial management tool for greenhouses and nurseries. They give producers precise measurements of the soil moisture content, allowing them to fine-tune fertilizer use, improve irrigation systems, and prevent overwatering or underwatering of plants. Growers can conserve water, cut expenses, and guarantee that their plants always get the right quantity of water by utilizing moisture meters regularly.

why you need lots of readings?

It’s crucial to remember that the moisture of the soil levels might change based on the time of day, the weather, and other variables while utilizing moisture meters. Because of this, it is advised that producers take many readings at various times and places to obtain a more accurate picture of the soil’s moisture content.

mind all factors

Growers should be mindful of additional variables including temperature, humidity, and air movement that might impact soil moisture levels in addition to employing moisture meters. For instance, soil can dry up rapidly in high temperatures and low humidity, but it can also stay moist for a longer time in low temperatures and high humidity. Because soil can dry out more quickly in the wind, air movement can also have an impact on soil moisture levels. Growers may make better judgments regarding irrigation and other management techniques by keeping an eye on these variables in addition to the moisture of the soil content.

There are errors

It’s also crucial to remember that moisture meters may only sometimes give accurate readings and are error-proof. The precision of moisture readings can be impacted by soil compaction, salt, and organic matter. Producers should utilize moisture meters as a tool in addition to other management techniques like visual inspections and crop monitoring to ensure that their plants are getting the right quantity of water.

our advice

Moisture meters are a useful management tool for nurseries and greenhouses. They may assist producers in identifying drainage issues, fine-tuning fertilizer use, maximizing irrigation, and choosing and placing crops wisely. To ensure that plants get the right amount of water and nutrients, moisture meters should be used in addition to other management techniques. Growers may increase crop yields, use less water, and save money by constantly monitoring soil moisture levels and considering other factors.
