Moisture Mapping A Guide to Soil and Plant Moisture Monitoring

Moisture mapping is a valuable tool used in agriculture and horticulture to monitor the moisture levels of soil and plants. It helps farmers optimize irrigation strategies, which can result in increased crop yields and reduced water usage.

How to Monitor Moisture in Soil?

Monitoring soil moisture is essential for maintaining optimal plant growth. Various methods can be employed to accurately measure soil moisture levels:

Tensiometers

Tensiometers are devices that directly measure soil water potential, which provides an accurate indication of the moisture content.

Soil Moisture Sensors

Soil moisture sensors detect the dielectric constant of soil, which varies with moisture levels. These sensors are simple to use and relatively inexpensive.

Neutron Probes

Neutron probes emit neutrons into the soil, and the amount reflected back gives an indication of soil moisture content. This method is more expensive but accurate.

Volumetric Water Content Sensors

Volumetric water content sensors directly measure the water volume present in a known soil volume. They provide real-time and accurate moisture readings.
