Web13 mrt. 2024 · It is a scale used to measure the acidity or alkalinity of a solution. The pH scale uses a range from 0 to 14, with 7.0 indicating neutrality. Numbers beginning at 7.0 and moving toward 0 indicate acidity, while the numbers beginning at 7.0 and moving toward 14 indicate alkalinity, so the scale divides acids from bases. WebA pH test measures soil acidity or alkalinity. A pH 7.0 is considered neutral. An acid soil has a pH value below 7.0. Above pH 7.0 the soil is alkaline. pH 3.0 - 5.0 Very acid soil Most plant nutrients, particularly calcium, potassium, magnesium and copper, become more soluble under very acid conditions and are easily washed away
