Hey Cheryl...The EasyBloom sensor measures and records volumetric water content of the soil. When the data are uploaded to the website, the algorithms will do the rest; however, the consumer will be able to see in graphical form the level of moisture in the soil. The watering recommendations in our algorithms are derived from scientific literature. In these papers, the watering thresholds recommended are used to promote vigorous plant growth. To address the issue of measuring pH in the soil: a decision had to be made about what to measure in the soil at any one given time. The argument for soil moisture is a strong one. When you consider most plants' demands for water are exponentially larger than any other nutrient (nitrogen, potassium, etc.), water is the most important nutrient. Additionally, improper watering is one of the primary reasons why plants will suffer by the hand of the home gardener. Since water in the soil is so very important for the well being of the plant and that is so easily adjusted by the home gardener, the EasyBloom sensor measures, records and monitors volumetric water content in the soil. Thanks as always. --Robby
