This Digital 3-Way Analyzer will provide you with the ability to quickly and easily test soil pH, temperature, and fertility. The pH function reads the soil acidity/alkalinity, while the temperature function allows you to find out when the soil is the proper temperature for planting. The fertility function reads the combined levels of nitrogen, phosphorus, and potash to determine the nutrient health of the soil. The Digital 3-Way Analyzer helps take the guesswork out of gardening.
