D. The yield can be improved by adding some organic matter
E. The yield can be improved by adding common salt
The correct option is D A and C
The soil has become more acidic and the yield can be improved by adding slaked lime to the soil. Usually, lime is calcium oxide or calcium hydroxide, but the term is also used to describe a wide range of calcium-containing compounds. Agricultural lime is usually calcium carbonate or limestone. All of these soil conditioners neutralize acids and make the soil less acidic.
