Measures soil pH just like the Item #1840, but also has a separate probe for fertility measurements. Comes with instruction booklet on how to alter pH and fertility to meet your needs.

HERE ARE SOME EASY STEPS FOR USING THE pH/FERTILITY TESTER:

• Simply push the probe into wet soil.
• The meter needle will register pH levels on a scale of 3.5 to 9.0
• The meter needle will register fertility levels on a scale of too little, ideal, too much
• Check you reading against the list of pH preferences and fertility preferences included with the meter, to find those plants that best suit your garden conditions.
• Details are included on how to alter the pH of your soil and fertility to fit specific plant requirements.
