Adding eggshells to soil does not increase alkalinity but instead increases acidity due to the presence of calcium carbonate. Lime is used to raise soil pH effectively.
False. Adding eggshells to soil actually increases its acidity due to the presence of calcium carbonate which is a weak base that reacts with water to form carbonic acid, lowering the soil pH.
The use of lime is the most effective way to raise soil pH, as it contains calcium carbonate which neutralizes acid in the soil.
Cation exchange capacity influences the amount of lime required to raise soil pH, as soils with high CEC require more lime to change pH levels.
