Digital soil water temperature and salt sensor is an integrated intelligent device mainly used for real-time and accurate monitoring of three key indicators: temperature, moisture content, and salt concentration in soil environment. Its digital design enables it to have higher accuracy, anti-interference ability, and data transmission efficiency, and is widely used in fields such as agriculture, ecological environment, water conservancy engineering, geological exploration, etc. The following is a detailed introduction to its core function:
1. Agricultural production and irrigation management
Precision irrigation decision-making
By monitoring soil moisture content (such as volumetric moisture content and relative humidity), combined with crop water demand patterns, on-demand irrigation can be achieved to avoid water resource waste and root hypoxia caused by excessive watering, or crop drought and yield reduction caused by insufficient watering.
Salt stress warning
Real time monitoring of soil salinity (such as electrical conductivity EC value), warning of soil salinization risks, guiding rational fertilization and improvement measures (such as salt washing and crop rotation), especially suitable for saline alkali land management and facility agriculture (such as greenhouses).
Temperature control
Monitor soil temperature changes to provide reference for sowing time, crop variety selection (such as suitable temperature for seed germination), and assist greenhouse temperature control system in regulating ground temperature.
2. Ecological environment monitoring and research
Research on Soil Plant Atmosphere Continuum (SPAC)
Synchronize monitoring of soil water, heat, and salt dynamics, combined with meteorological data, to analyze ecosystem water cycling, energy exchange, and material migration processes, supporting research on the impact of climate change on soil environment.
Wetland and groundwater protection
Monitor soil water and salt changes, assess wetland degradation risks and groundwater pollution diffusion trends, and provide data support for ecological restoration.
desertification combating
Monitor soil water and salt changes in arid and semi-arid areas, guide vegetation restoration and soil and water conservation measures.
3. Water conservancy engineering and hydrological models
Soil moisture monitoring network
Deploy sensors at multiple sites to build a regional soil moisture monitoring network, providing basic data for flood warning, drought resistance scheduling, and water resource management.
Calibration of hydrological model parameters
Provide real soil water and heat parameters, optimize hydrological models (such as SWAT, HYDRUS), and improve the simulation accuracy of precipitation runoff, groundwater recharge and other processes.
Farmland drainage design
By long-term monitoring of soil water and salt dynamics, optimizing the layout of farmland drainage systems, and reducing the risk of waterlogging and secondary salinization.
4. Research and Teaching Applications
Research on Soil Physical Properties
By inverting soil porosity, permeability, water holding characteristics and other parameters through hydrothermal and salt data, we can gain a deeper understanding of soil structure and function.
Evaluation of Fertilizer and Pesticide Effects
Monitor changes in soil salinity and moisture, study fertilizer leaching and pesticide migration patterns, optimize fertilization plans, and conduct environmental risk assessments.
Teaching Experiment Platform
Provide intuitive soil environmental parameter monitoring tools for majors such as agriculture and environmental science, and support practical teaching and scientific research training.
5. Facility agriculture and smart agriculture
Automated Irrigation System Integration
Connect with intelligent irrigation controller to trigger irrigation based on soil moisture threshold, supporting remote monitoring and Internet of Things (IoT) management.
Precise control of greenhouse environment
Combining temperature and humidity sensors to optimize greenhouse microclimate and improve crop quality and yield (such as strawberry and vegetable cultivation).
Precision Agriculture Decision Support
Integrating drone and satellite remote sensing data to generate a distribution map of farmland water and salt, guiding variable fertilization and zoning management.
6. Geological hazard warning and soil improvement
Landslide and debris flow warning
Monitor soil moisture changes, combine terrain and landform data, evaluate slope stability, and warn of geological hazard risks.
Tracking of soil improvement effect
Real time monitoring of water and salt changes and evaluation of the effectiveness of improvement measures in the process of saline alkali land improvement and polluted soil remediation.
