Moisture mapping is a process that allows farmers and gardeners to visualize soil moisture levels and plant water stress. This information can be used to make informed decisions about irrigation and other water management practices.

How do you monitor moisture in soil?

There are a number of methods for monitoring soil moisture, including:

• Tensiometers: Tensiometers are devices that measure the tension or pressure in soil water. As the soil dries out, the tension increases, which can be measured by the tensiometer.
• Soil moisture sensors: Soil moisture sensors measure the electrical conductivity of soil, which is affected by the amount of water present. These sensors can be used to measure soil moisture at different depths.
• Neutron probes: Neutron probes use a radioactive source to measure the amount of hydrogen in soil. Hydrogen is a major component of water, so the amount of hydrogen in soil can be used to estimate soil moisture.

Once soil moisture has been measured, it can be mapped using a variety of software programs. This allows farmers and gardeners to see areas of high and low moisture, which can help them make decisions about where to irrigate or apply other water management practices.
