OBJECTIVE FORESTRY

Detailed explanation-1: -Soils can be classified according to their pH value: 6.5 to 7.5-neutral. over 7.5-alkaline. less than 6.5-acidic, and soils with pH less than 5.5 are considered strongly acidic.

Detailed explanation-2: -Soil pH is measured on a simple scale that ranges from 0 to 14. The midpoint, pH 7, denotes a neutral soil, which is neither acid or alkaline. Anything below pH 7 is acidic (or ericaceous), and the lower the pH number, the more acidic the soil is. Alkaline soils are those with a pH above pH 7.

Detailed explanation-3: -The range goes from 0-14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.

Detailed explanation-4: -Any solution that has a pH of less than 7 is considered acidic, and anything above a pH of 7 is basic.

Detailed explanation-5: -If the pH of a solution is less than 7, the solution is called acidic; In an acidic solution, then, the concentration of hydrogen ions is greater than the concentration of hydroxide ions. if the pH is about 7, the solution is neutral; if the pH is greater than 7, the solution is called basic.
