Soil reaction is related to the quantity of soil origin and object elements that are the major prachubuak land spotted anchored suction: calcium (Ca 2 +), magnesium (Mg + 2), sodium (Na +) and potassium (K +)
Soil reaction is correlated with soil. And the amount of the alkaline earth cations major land held vacuum Calcium (Ca + 2), magnesium (Mg + 2), sodium (Na +) and potassium (K +).
Soil reaction associated with soil parent materials. Strontium cation and alkaline land main suction anchor, including calcium (Ca 2), magnesium (Mg 2), sodium (Na) and potassium. (K).
