When water is drained out from soil that creates oxidization condition which is responsible for increasing acidity of that soil.

Eliecer Miguel Cabrales Herrera

Los suelos sulfatados ácidos (SSA) se vuelven más ácidos cuando se drenan, debido a que el azufre se oxida y se genera más sulfatos y protones:

S + O2 --> SO3

SO3 + H2O --> H2SO4

H2SO4 --> 2H + SO4
