2.7. is the acid-alkaline soil. The living conditions of acid-alkaline soil, it can be verified. Usually used as the acid-alkaline pH value called or written symbol popular in British soil pH range of APA on the rocks are typically between 3.0-9.0 pH of about 7.0 indicate a middle ground. That is, there is a clay that is acid and the alkali is made to be equally fit. A value that is lower than 6.0 7.0, such as acid soil conditions dictate. In this case, when the soil has a pH 6.0, you will know whether the ground is either weak acids. There is more acid soil with a pH 7.0 (neutral) ten times. PH value of the soil more acid, how much of a decline, only stronger. Soil pH is acid pH 6.0 5.0 is more than ten times as much as 100 times the soil pH value of pH 7.0, each one will tell you different as different acids. Ten times Soil pH above 7.0 is alkaline, it will say the living conditions of the soil, the better the value much higher than 7.0 alkaline, high integrity.
