Soil Moisture Meter

To measure soil moisture, rod or two-prong hygrometers designed for this purpose can be used.

Humidity sensors measure the volume of soil water. Because direct gravity measurement of free soil moisture requires harvesting, drying, and soil sample weight, soil moisture sensors measure volumetric water volume indirectly using some other soil properties such as electrical resistance, constant di Are responsible for electricity or interaction with neutrons. The relationship between the measured properties of soil moisture must be calibrated and can vary depending on environmental factors such as soil type, temperature or electrical conductivity. Large-scale microwave radiation reflected through soil moisture is used for remote sensing in hydrology and agriculture. In manual samples, portable probe soil moisture meters are used by farmers or gardeners.

Soil moisture sensors are commonly referred to as sensors that measure the volume of water. Another class of sensors measures another characteristic of moisture in soils called water potential. These sensors are commonly referred to as soil water potential sensors and include tensiometers and gypsum blocks.

Agriculture

Measuring soil moisture is important for agricultural applications to help farmers manage their irrigation systems more efficiently. By knowing the exact soil moisture conditions in their fields, not only are able farmers generally using less water to grow their crops, but they can increase crop yield and quality by improving soil moisture management during plant growth stages.

Irrigation of green space
in urban and suburban areas, landscapes and residential lawns use soil moisture sensors to communicate with an irrigation controller. Connecting a soil moisture sensor to a simple irrigation clock turns it into an "intelligent" irrigation controller that prevents excess water when the soil is wetting, for example following a rainstorm. Avoid re-irrigation.

Golf courses, for example, use soil moisture sensors to increase the efficiency of their irrigation systems and to prevent over-irrigation and the saturation of manure and other chemicals into the ground.

Scientific and research
Soil moisture sensors are used in many research projects, for example in agricultural and horticultural sciences, including soil and water planning. Climatic research, or environmental science, including auxiliary sensors for measuring soil respiration.
Simple sensors for gardening are
available in relatively inexpensive and simple devices that do not require electricity and to check if plants have enough moisture to grow. . After placing a probe in the soil for approximately 60 seconds, the hygrometer indicates that the soil is too dry, wet, or damp for plants.
