Does the sensor measure fertilizer? How about NPK?
The PlantSmart Plant Sensor measures overall soil fertility and recommends fertilizers for specific plants. Store-bought soil fertility tests, which measure NPK (named after the three elemental components of fertilizers – nitrogen, phosphorus, and potassium), are typically chemical-based and can be cumbersome to use. The PlantSmart Plant Sensor measures soil electronically, which is far more practical for most gardeners. Our sensor measures bulk salts, providing a good indication of the amount of fertilizer in the soil. Our website recommends specific fertilizers according to the plant’s horticultural needs, accounting for NPK requirements in your garden. Over time, the NPK ratio in the soil will approach the ideal levels for your plant.
