How Can Soil Moisture Sensors Keep Your Crops Healthy During Heatwaves?
Water is a critical resource for all plants, especially during hot summer days. This can impact tiny and slow-growing vegetables to a great extent, which may lead to damaging heat stress effects. Water stress is one of the most important factors affecting crop yield, quality, and harvest time. It can also have an impact on your crop's growth cycle and food quality. Soil moisture sensors can help with the monitorization of crops' water status from a distance allowing to make decisions accordingly.
Why is Monitoring Soil Moisture Important in Smart Agriculture?
Soil moisture is a key factor in smart agriculture because it affects the health of plants, which in turn affects the health of our food.
Soil moisture is regulated by the evapotranspiration process, which means that plants use water from the soil to produce their own food. The amount of water used by each plant depends on its size and the type of soil it is growing in.
If your soil is too dry, your plants will be unable to produce enough food—this means they need more water than usual and could wilt or even die if you do not give them enough attention. If your soil is too wet, that same plant might struggle to grow or even drown!
Monitoring soil moisture can help you keep track of how much water your plants need and when they are getting enough.
What Are the Main Advantages of Installing Soil Moisture Sensors?
Soil moisture sensors are great for the following reasons:
- They help save money on irrigation systems
- They reduce water loss due to evaporation
- They provide a more accurate measurement of soil moisture
Soil moisture sensors provide you with a way to know if your soil is wet or dry. You can use this information to decide how much water to add and which will help you avoid over-watering and over-fertilizing.
You can also use soil moisture sensors to figure out the best time of year for planting. If the soil is too dry, it will not be able to hold water well, so plants will not grow as well, and yield may suffer. If the soil is too wet, plants may not have enough nutrients to survive and thrive.
And finally, there are some benefits in terms of energy savings. When you have dirt that is constantly being watered or fertilized, it uses up a lot of energy—and that is not something we want to do! By installing soil moisture sensors in your yard, you will save money on power bills while also ensuring that your lawn stays healthy and beautiful all year round!
How Do Soil Moisture Sensors Work?
Soil moisture sensors are a great way to monitor soil conditions, and they are one of the most comprehensive ways you can monitor the health of your plants. Soil moisture sensors work by measuring changes in atmospheric pressure, which is really just a measure of how much water is present in the soil.
Plants need water in order to survive, so if there's not enough water available to them, it will be reflected in their growth rates and overall health. Therefore, it is so important to track how much water your plants are getting over time—if you notice an issue, then you can take steps to correct it before things get out of hand!
Soil moisture sensors rely on variations in the amount of moisture in the soil to determine whether there is enough water to support plant growth.
The soil moisture sensor's operation is simple.
- Using a fork-shaped probe with two exposed conductors, the potentiometer-like variable resistor can be used to measure soil moisture content.
- The more the soil moisture, the greater the resistance.
- The higher the soil's conductivity, the lower the resistance will be.
- Reduced soil moisture causes low conductivity, which in turn raises resistance.
- The sensor generates an output voltage based on resistance, and this voltage can be used to calculate the moisture content of a sample.
Soil moisture (volumetric water content) can be measured using a variety of technologies, including:
The Operating Frequency of an oscillating circuit is used to measure the dielectric constant of a specific volume element around the sensor.
TDT (Time Domain Transmission) and TDR (Time Domain Reflectometry) are two methods of measuring the passage of time. The propagation speed along a subterranean transmission line is used to determine a volume element's dielectric constant.
Infrared Humidity Sensors: Soil moisture content can be estimated between a neutron source and detector probe using water's moderator characteristics.
The Resistivity of The Soil: Soil moisture content can be measured by seeing how much electricity flows between two electrodes.
Soil Voltage can be used to determine how much water is in the soil because water is an electrolyte and creates electricity. Galvanic cells are the brains behind this idea.
Soil moisture sensors have many applications, including:
- Monitoring irrigation systems for optimal water usage and efficiency
- Measuring crop yields and quality
- Determining how much fertilizer and pesticides to apply to crops
- Determining if specific crops are doing well based on their needs
They are also used in construction projects, where they can be used to monitor underground utilities such as water pipes or gas lines.
Soil moisture sensors are being used in urban and suburban landscapes and residential lawns to communicate with an irrigation controller. Irrigation cycles can be prevented when the soil is already wet, such as after recent rainfall, with the simple addition of a soil moisture sensor to an irrigation clock.
To prevent over-watering and the leaching of fertilizers and other chemicals into the soil, golf courses are adopting soil moisture sensors to improve their irrigation systems.
Soil moisture sensors are utilized in a wide range of scientific investigations, including irrigation planning, climate research, environmental science, solute transport studies, and as auxiliary sensors for soil respiration assessments, to name just a few.
