When measuring pH, the higher the soil pH number, the:
|
|
less alkaline
|
|
|
more acidic
|
|
|
more alkaline
|
|
|
more neutral
|
Explanation:
Detailed explanation-1: -Soils can be classified according to their pH value: 6.5 to 7.5-neutral. over 7.5-alkaline.
Detailed explanation-2: -The pH scale ranges from 0 to 14, with 7 being neutral. A pH value below 7 indicates the soil is acidic, while values above 7 are alkaline. Each unit change in the pH scale is a 10-fold difference in acidity or alkalinity. For example, soil with a pH of 8 is ten times more alkaline than soil with a pH of 7.
Detailed explanation-3: -Soil pH is a measure of the concentration of hydrogen ions in the soil solution. Low pH values (< 5.5) indicate acidic soils and high pH values (> 8.0) indicate alkaline soils. Soil pH between 5.5 and 8 is not usually a constraint to crop or pasture production.
