So testen Sie Bodenfeuchtigkeit, Temperatur, EC, pH und NPK

Soil testing is essential for agriculture, horticulture, and environmental monitoring, as it provides valuable insights into the health of the soil and the plants it supports. The ES-S225 series soil sensor is a high-precision, sensitive tool designed to measure various soil parameters such as moisture, temperature, electrical conductivity (EC), pH, and NPK (Nitrogen, Phosphorus, Potassium). This article will guide you through two primary methods for using the ES-S225 sensor—quick test and buried measurement methods—along with key precautions to ensure reliable and accurate results.

1. Quick Test Method

The quick test method is designed for fast and reliable soil measurements in the field. It’s ideal for checking soil conditions at a specific location or for immediate analysis.

Steps:

1. Select the Measurement Location: Choose a location that represents the soil you wish to measure. Avoid areas with rocks or obstructions that may affect the sensor’s performance. It’s important that the sensor needle does not make contact with hard objects.
2. Prepare the Soil: Carefully remove the surface soil at the desired depth for measurement. Ensure that the remaining soil is not disturbed, as the sensor’s accuracy depends on maintaining the original tightness and structure of the soil beneath.
3. Insert the Sensor: Hold the sensor vertically and insert the steel needle into the soil. Ensure that the sensor is inserted smoothly without shaking or tilting it left or right. This helps in obtaining accurate readings.
4. Multiple Measurements: To enhance the accuracy of the reading, it is recommended to perform the measurement several times within a small range at the same location. Calculate the average value for more reliable results.

Benefits:

• Quick and easy to perform in the field
• Suitable for periodic or spot checks of soil conditions
• Provides immediate feedback for decision-making in farming, gardening, or environmental monitoring

2. Buried Measurement Method

The buried measurement method is more suitable for long-term monitoring, as it allows for the sensor to stay in the soil for extended periods. This method provides continuous, stable readings over days, weeks, or even months, making it perfect for observing the soil’s behavior under natural conditions.

Steps:

1. Prepare the Pit: Dig a pit with a diameter of at least 20 cm. The pit should be deep enough to insert the sensor at the desired depth for measuring soil conditions.
2. Insert the Sensor: Horizontally insert the sensor’s steel needle into the pit wall at the predetermined depth. Be careful to position the needle correctly to ensure accurate measurements.
3. Re-fill the Pit: After inserting the sensor, refill the pit with the same soil and ensure that it is tightly packed around the sensor. This step is crucial to maintaining the integrity and tightness of the soil, which affects the accuracy of the readings.
4. Stabilize and Monitor: Allow the sensor to stabilize in the soil for a period of time. After stabilization, measurements can be taken over several days or even longer, providing insights into the soil’s condition over time.

Benefits:

• Ideal for long-term monitoring
• Provides real-time data that can help track soil conditions over time
• Allows for the measurement of soil parameters at different depths

Precautions for Using the ES-S225 Soil Sensor

To ensure that your readings are accurate and that your sensor remains in good condition, keep the following precautions in mind:

1. Correct Needle Insertion: Always make sure that the sensor’s steel needles are properly inserted into the soil for reliable measurements.
2. Avoid Direct Sunlight: Do not allow the sensor to be exposed to strong sunlight, as it may cause overheating, leading to inaccurate readings.
3. Lightning Protection: When using the sensor in the field, be mindful of weather conditions, especially the risk of lightning. Ensure that the sensor is protected from potential lightning strikes.
4. Handle the Sensor with Care: Avoid bending the steel needle violently or pulling on the sensor’s lead wire. Do not subject the sensor to excessive force or impact.
5. IP68 Protection: The ES-S225 sensor is rated with an IP68 protection level, meaning it is waterproof and can be submerged in water. However, it is important not to leave the sensor in water for extended periods unless necessary for specific applications.
6. Radiofrequency Considerations: The sensor should not remain powered on for long periods when exposed to radiofrequency electromagnetic radiation in the air. It is advisable to turn the sensor off when not in use.

Conclusion

The ES-S225 series soil sensor is an excellent tool for accurately measuring various soil parameters, such as moisture, temperature, conductivity (EC), pH, and NPK. By following the quick test or buried measurement methods, users can gain valuable insights into soil health and make informed decisions about irrigation, fertilization, and other essential agricultural practices. Keep in mind the precautions to ensure that your sensor remains accurate and functional over time, providing reliable data for your soil monitoring needs.

With the ability to conduct both short-term and long-term soil testing, the ES-S225 series is a versatile solution for farmers, horticulturists, environmental scientists, and anyone interested in maintaining healthy soil for optimal plant growth.
