Moisture meter soil is a portable sensing device that is pushed into the soil or into an access tube that is placed in the soil for monitoring purposes. Moisture meter soil measures some physical property that is correlated to the level of moisture in the soil.
Having moisture meter soil nowadays is a must because soil moisture measuring is important to help in irrigation scheduling, estimating crop yields, and reservoir management. Soil moisture measurement also gives an idea about soil erosion, slope failure and the quality of the water. It also gives early warning of droughts and floods.
One common type of portable moisture meter soil is the electrical resistance block. This sensor works on the basis that water conducts electricity; soil with higher moisture levels will have a lower electrical resistance. Two types of commercially available electrical resistance blocks are gypsum blocks and granular matrix sensors. The blocks work when they are buried in tightly packed soil with no air pockets in a location that is representative of the field you are testing.
Another type is thermal dissipation blocks. This type of moisture meter soil is porous ceramic block that contains temperature sensor and small heater. It works on the basis that wet object heats up slower than dry object. Like the electrical resistance block, thermal dissipation block is buried tightly in the soil and read with hand held meter.
Tensiometer also includes one of moisture meter soil types. Tensiometer is water filled tube that has a porous ceramic tip that is placed in the soil. Tensiometer measures soil water tension and works best in coarse soils between 0 and 80 centibars. Tensiometer is simple to install and remove, but requires regular servicing in order to fill the tube with water. This type of moisture meter soil is often used in orchards, cultivated fields and fields with annual crops.
Meanwhile, neutron moisture meter is a moisture meter soil in which state-of-the-art electronics and radioactive sources are used. As the radioactive source can be harmful for health, using the neutron moisture meter requires a license. It gives accurate results, but it is expensive equipment.
To purchase the right moisture meter soil, first of all, compare the accuracy of the meters available in the market. Analog models show limited moisture levels with a less accurate reading than digital models. Digital models show levels from 0 percent to 40 percent compared to 10 percent to 28 percent advertised by some analog models.
Secondly, take note of how the moisture meter soil acquires moisture levels. Some meters have long, coiled cables that contain sensors to reach difficult areas. Then, compare models. Some digital models have a low-battery indicator and provide a considerable advantage over those with analog displays.
Thirdly, look for a protective cap to protect the sharp probe metering pins. Finally, read reviews and compare prices of moisture meter soil.
Soil Moisture Meter HydroSense CS620 is one of moisture meter soils you can choose out there. This moisture meter soil combines a compact, display and robust soil water sensing probes in one complete portable package to provide instant, accurate soil water content measurements.
This moisture meter can be used wherever there is a need for monitoring and managing soil water in a wide range of conditions. Each measurement takes less than one second and is obtained by inserting the probe rods into the soil and pressing a single button on the display unit.
Using this moisture meter soil, the user can either choose to display the actual volumetric water content in percentage or relative water content based on lower and upper values set before use. A choice of 12- or 20-cm long probe rods makes HydroSense the perfect tool for all soil moisture applications, including sports fields, race courses, golf courses, parks & forests, plant nurseries, school grounds and many more.
