Soil Moisture Indicator 30cm – 4-Colour LED Irrigation Tester

Handheld Soil Moisture Indicator, a simple field-testing tool designed to help farmers check moisture conditions around the crop root zone before watering. Insert the sensing probe into the soil, press and hold the operating switch, and within approximately 2–5 seconds the indicator displays the soil moisture condition using an easy 4-colour LED scale.

4-Colour Moisture Indication

• Blue – Ample Moisture: Irrigation is generally not required at the time of testing.
• Green – Sufficient Moisture: Soil moisture is adequate and immediate irrigation may not be necessary.
• Yellow – Low Moisture: Irrigation should be considered according to crop and field conditions.
• Red – Very Low Moisture: Indicates a low-moisture condition where irrigation may be required promptly.

Key Features

• Fast 2–5 Second Reading: Provides a quick indication of soil moisture conditions directly in the field.
• Up to 30 cm Sensing Depth: Allows moisture checking at depths closer to the crop root zone.
• Simple 4-Colour LED Display: Blue, Green, Yellow and Red indicators make the result easy to interpret without reading numerical values.
• Portable Field Tool: Suitable for taking readings at different locations across a field, farm, nursery or garden.
• Supports Irrigation Scheduling: Helps farmers make irrigation decisions based on actual soil moisture condition rather than relying only on visual judgement.
• Helps Avoid Unnecessary Irrigation: Allows the user to check whether useful moisture is still available around the root zone before operating the irrigation system.
• Easy to Operate: Insert, press, wait for the LED indication and interpret the moisture level.

How to Use

1. Select a representative location close to the crop's active root zone.
2. Insert the probe vertically into the soil to the required testing depth.
3. Press and hold the operating switch.
4. Wait approximately 2–5 seconds for the LED indication to stabilize.
5. Read the displayed colour and assess whether irrigation is required.
6. For larger fields, repeat the measurement at multiple representative locations rather than relying on a single reading.

Suitable Applications

• Agricultural fields
• Vegetable crops
• Sugarcane
• Fruit crops and orchards
• Nurseries
• Polyhouses and protected cultivation
• Gardens and landscaping
• Irrigation-management demonstrations and farm advisory work

Why Check Root-Zone Moisture?

The soil surface can appear dry even when useful moisture is still available deeper in the root zone. Likewise, field conditions can vary from one location to another. Checking moisture closer to the crop root zone provides additional information for deciding whether another irrigation cycle is actually required.

Using soil-moisture information as part of irrigation scheduling can help reduce unnecessary pumping while also identifying low-moisture conditions before they become severe.

Best Practices for Field Testing

• Take readings close to the active crop root zone.
• Check more than one point in larger or non-uniform fields.
• Test different soil zones separately where soil type or drainage varies significantly.
• Avoid forcing the probe into stones or very hard material.
• Clean soil residue from the probe after use.
• Follow the supplied operating instructions regarding timing after irrigation.

Important Note

This device provides a practical indication of soil moisture status to support irrigation decisions. Actual irrigation requirements also depend on crop type, crop growth stage, rooting depth, soil texture, weather and field conditions.
