pH Measurements pH is the measurement of hydrogen ion concentration (H+) in water or soil. A pH of 7 is considered neutral. A pH below 7 is considered more acidic and a pH above 7 is considered more basic or alkaline. Water pH is important for plant management because it affects the solubility of fertilizers and the effectiveness of insecticides and fungicides. Below is a pH scale that ranges from 0 – 14 pH. Most plants have an optimal pH between 5.8 and 6.4 pH in soil-less media. For direct soil applications, a typical pH range of 6.5 – 7.0 pH is more common. Affects the solubility of minerals...
