Soil NPK Sensors

Nitrogen is a key component of proteins and is essential for promoting stem and leaf growth, as well as fruit development. Phosphorus aids in flower bud differentiation and supports early flowering and fruiting in tomatoes. Potassium helps strengthen stems, boosts plant resistance to cold, and increases sugar content and vitamin C levels in fruits.

A Soil NPK sensor detects nitrogen, phosphorus, potassium, and other elements in the soil, providing essential nutrients for plant growth. It assesses soil fertility by measuring changes in conductivity resulting from varying concentrations of nitrogen, phosphorus, and potassium.

Soil NPK sensors are commonly employed in agriculture to assess soil conditions and enhance crop growth and yield. They are useful for soil health assessments, farmland management, optimizing planting programs, and promoting environmental protection.
