What is Soil pH?
Soil pH testing is done to see how acidic or alkaline your soil is. pH means potential Hydrogen. It measures the number of H+ ions in the soil water.
It's a logarithmic scale that goes from 0 to 14 with 0 being most acidic, 7 being neutral and 14 being most alkaline. Because it's a logarithmic scale each jump is a ten fold increase so a soil with a pH of 5 is 10 times more acidic than one with a pH of 6 and a 100 times more acidic than one with a pH of 7.
