    Proving Tests

    Example of EC_Pore measurement

    Nutrient solution with a concentration of 1.8 dS/m is used for irrigation from an irrigation tube. The EC_Pore measurement (fertilizer content in soil) matches the concentration of the nutrient solution.
    Nutrient solution concentration was changed in November according to growing conditions; the sensor was still providing accurate measurements.

    Soil classification: Fine-grain turfy gley lowland soil
    Soil classification code: F2e6t1 (farmland soil map)
    Example of EC_Pore measurement
    EC value of nutrient solution and EC_Pore value detected in soil are mostly the same

    Examples of water retaining capacity of different soil textures

    Different soil textures as shown in the picture can be found between adjacent farm fields.
    Water movement and retention can vary with soil type. Instead of uniformly irrigating based on weather conditions, it is important to perform proper irrigation according to soil type based on sensor values.

    Image 2 of Examples of water retaining capacity of different soil textures
    Image 3 of Examples of water retaining capacity of different soil textures

    Soil texture and water movement can vary substantially from one area to the next; irrigation plans must account for the water retaining capacity of each individual field.

    Projected soil drying and irrigation plans

    Sensor values can also be used to estimate water content drop in relation to continuous fair weather or increase in relation to rainfall.
    Irrigation can be planned with appropriate amount of water at the right time by using this estimation and weather forecasts.

    Identifying the relationship between insolation/precipitation and water content and pairing it with weather forecasts makes it possible to propose better irrigation plans.
    It also makes it possible to reduce unnecessary irrigation work.
