Application of soil moisture sensor agriculture

Background:

Any farmer will tell you that throughout the growing season, soil conditions are constantly changing. Soil conditions are influenced by weather, row density, crop patterns, and more. During this period, plants are constantly changing and adapting to their environment. Plant roots and shoots grow in the most favorable soil for growth. To help farmers adapt to these changing conditions, soil and water sensors are being used. In the past, farmers collected soil and water conditions from the fields by surveying and collecting soil and plant samples. These samples are sent to a laboratory for testing, which can take precious weeks to produce results. Today, thanks to recent developments in soil and water monitoring, critical information is being received from real-time measurements in the field, helping farmers make faster and more accurate crop production decisions. soil moisture sensor agriculture can help people better.

About Soil Monitoring Equipment

Farmers now use sensors to monitor specific areas of the field, allowing them to respond quickly to changes in the land and crops. Rapid response is made possible by using smaller, simpler sensors. This allows farmers to turn soil sensor readings, weather and historical crop data into actionable perceptions by looking at the bigger picture.

The soil in a field is never consistent, and this inconsistency is often amplified at the sensor level. Multiple sensors can statistically improve accuracy and track activity changes, which are variable across the field. Areas that were wet in the spring can become drier as crops grow and run out of water. Sensor-based measurements provide more detail, such as moisture content, fertilizer availability, and plant responses to variable conditions, including temperature and light. These sensor measurements allow farmers to take action when field conditions, such as low water levels, create a stressful response.

Soil moisture sensors estimate water content based on the dielectric constant of the soil. The dielectric constant indicates the ability of soil to transmit electricity. As soil moisture content increases, the dielectric constant of soil increases because water has a much greater dielectric constant than other soil constituents, including air. Therefore, the measurement of the dielectric constant gives a predictable assessment of the water content.
Most soil sensors are single point sensors. They measure at one location. Single-point sensors can measure soil moisture and temperature, or soil moisture, temperature, and salinity. The sensor can be completely buried in the soil. Some sensors measure volumetric water content along the length of the sensor.
To optimize irrigation, it is important to measure soil moisture at multiple depths, as it indicates water penetration throughout the root zone. The main benefit of using a soil profiling probe is the reduced cost of installing multiple single point sensors and the requirement to dig a large hole to bury them at the proper depth.

Soil Moisture Sensor

Profile probes are usually manufactured as a pair of parallel rings along the probe and are usually installed in a plastic or PVC access pipe through which the electric field between the sensor and the soil must pass. A profile probe that does not require an access pipe will provide greater accuracy.

Sensors that measure volumetric water content are often referred to as soil moisture sensors. Soil volume moisture sensors measure the water content of the soil. These sensors can be used to estimate how much water is stored in the profile or how much irrigation is needed to get the desired amount of water in the soil. These sensors can be used for quick measurements or installed for long-term measurements.

Volumetric water content is a measure of the percentage of water in the soil as a percentage of the total mixture and is often referred to simply as “soil moisture”. Both the amount of water a soil can store and its availability to plants depends on the soil type.
