The soil moisture monitoring system is one of the methods for rapid determination of soil water content. It is relatively unaffected by the soil type and does not damage the soil. It is suitable for repeated and continuous measurement on the surface layer and profile, with high resolution and high precision. It can measure the moisture of a certain point in the soil, and can also measure the water content of multiple points by continuously using multiple sensors. In addition, the soil moisture monitoring system has no radiation and does not cause harm to the human body.

Each soil moisture monitoring system soil moisture sensor must be calibrated according to local soil characteristics before application. The calibration is performed by the cubic equation conversion method. In the range of 0 to 60% (m3/m3), the conversion result of the soil water content can be obtained by setting the constant of the following cubic polynomial. In many areas, multiple experiments with sensors related to the soil moisture monitoring system are required, and the location is constantly changed to obtain a stable correlation before it can be applied to public opinion monitoring.

Hydrogen atoms present in the soil in an indiscriminate manner have a much slower effect on fast neutrons than other heavy atoms. Therefore, it can be considered that the effective intensity of slow neutrons has a close relationship with the moisture content in the soil. The content of various components in the soil varies widely, and the density and porosity are also different. The soil moisture monitoring system needs to take the ideal area of ​​the soil sample and obtain good correlation results.

The soil moisture monitoring system is not only suitable for large-scale continuous dynamic monitoring of field water in the field, but also meets the needs of indoor soil moisture measurement. It is a promising soil moisture measuring device. Sensitive to moisture, the average water content can be measured as a function of depth, and the range of measurement is wide. This method does not need to sample, does not disturb the soil, and is not affected by the physical state of water (such as freezing and crystal water). After the aluminum pipe is buried, it can be used for a long time, and the soil moisture monitoring system measures quickly.

Greenhouse Seedling Bed

A seedbed or seedling bed is the local soil environment in which seeds are planted. Often it comprises not only the soil but also a specially prepared cold frame, hotbed or raised bed used to grow the seedlings in a controlled environment into larger young plants before transplanting them into a garden or field. A seedling bed is used to increase the number of seeds that germinate.
