In one field trial comparing no-till and conventional tillage, soil samples taken after 15 years without liming revealed that the pH of the upper 15 cm was lower on the no-till plot than on the conventional plot. Which of the following most likely accounts for this difference?
A) Plowing mixes the surface soil more thoroughly. B) Al3+ ions are tied up by the organic matter thereby releasing H+ ions. C) Acidifying effects of nitrogen-containing fertilizers. D) Earthworms were more active in the no-till plot. E) Organic decomposition produced more organic acids in the no-till plot.
