4-Way pH Soil Tester

Increase the yield of your vegetable or flower garden by making sure it's getting enough light, and the soil has the proper moisture, pH and fertility. Just stick this analyzer's two prongs into ground soil or potting soil and flick the switch to run an analysis of all four attributes. Multi-colored display helps you determine if your soil is within the ideal pH range (pH numbers are included for 350 plants); indicates if the soil has the proper balance of nitrogen, potash and phosphorous, based on USDA standards; reads light level and moisture level. Testing takes about a minute. Instructions included. No batteries required.
