What is a Soil Moisture Meter?

A soil moisture meter tells you how much water is in the soil. Gardeners, farmers, and plant lovers use it to water plants at the right time. Here’s how it works:

Types of Soil Moisture Meters

• Probe Meters: Have metal probes that go into the soil. Water conducts electricity between the probes, showing moisture levels.
• Tensiometers: Measure how tightly soil holds water.

How It Works

1. Insert the probe into the soil.
2. The meter measures electrical resistance or capacitance.
3. More moisture means less resistance, and the meter shows the result.

Why Use It?

• Gardening: Prevents overwatering and underwatering.
• Farming: Helps with irrigation and saves water.

Reading the Meter

• Some meters show a simple dry-to-wet scale.
• Digital meters may show percentages or color codes (red for dry, green for moist).

There are many types of soil moisture meters, from basic home tools to advanced devices. Choose one that fits your needs!
