Soil Tester Nutrient Content Soil Nutrient Tester BK-Y6A (CAT#: STEM-OEM-0317-ZJF)

This multi-parameter soil analyzer is used to detect essential nutrients and chemical properties in soil, plants, and fertilizers. It measures available nitrogen, available phosphorus, available potassium, organic matter content, soil pH, and salinity. Ideal for agricultural and environmental applications, it supports soil health monitoring and nutrient management.
