Which of the following would occur when lime is added to the surface of a soil at pH 6.0?
A) The release of H+ ions from the exchange complex would help reduce the soil pH
B) Aluminum toxicity would increase in the vicinity of the limestone.
C) CO2 from root and microbial respiration would quickly solubilize the CaCO3 and increase its rate of downward movement
D) Conservation tillage would increase the pH of the subsoil
E) Earthworms would help move the limestone down into the soil profile.
