Technical Field

[0001] This utility model relates to the technical field of soil nutrient content analysis equipment, specifically a field soil rapid testing device with encapsulated reagents. Background Technology

[0002] In modern agricultural production, soil testing plays a crucial role. Through soil testing, we can obtain data related to soil quality, such as soil moisture, nutrient content, pH, and pollution levels. Nutrients in the soil are essential for plant growth, and both insufficient and excessive nutrients will have a negative impact on crop growth. Therefore, a reasonable soil nutrient content is crucial for crop growth. Traditional methods for soil nutrient testing typically employ chemical or biological analysis. These methods are complex to operate, and the testing equipment for each step is relatively scattered. This requires staff to transport samples processed in one step to the next, which is time-consuming. Furthermore, because the testing equipment is scattered, it is not possible to carry the equipment to the sampling site for on-the-spot testing, thus failing to meet the demand for rapid and convenient testing. Therefore, it is necessary to research a portable, rapid, and simple soil nutrient testing device.
