The soil nitrogen, phosphorus, and potassium three-in-one fertility sensor is suitable for detecting the content of nitrogen,
phosphorus, and potassium in the soil, and determining the fertility of the soil by detecting the content of nitrogen, phosphorus, and potassium in the soil, thereby facilitating the systematic assessment of the soil condition. Can be buried in the soil for a long time, resistant to long-term electrolysis, corrosion resistance, vacuum potting, completely waterproof.
