Moisture Mapping is a vital tool for farmers and land managers, allowing them to optimize irrigation practices, improve crop yields, and conserve water.

How do you measure soil moisture without a sensor?

There are several methods to measure soil moisture without a sensor:

• **Visual Inspection**: Observe soil color and texture. Dry soil is often lighter in color and more crumbly.
• **Feel Test**: Squeeze a handful of soil. Moist soil will form a ball but not release water when squeezed.
• **Plant Indicators**: Observe plant health. Wilting or yellowing leaves can indicate water stress.
• **Resistance Measurement**: Insert a metal rod into the soil and measure the electrical resistance. Dry soil will have higher resistance.
• **Tensiometer**: Use a tensiometer to measure the soil water tension. Higher tension indicates drier soil.

By understanding the principles of Moisture Mapping and employing these methods, farmers and land managers can effectively monitor soil moisture and make informed irrigation decisions.
