A farmer may treat the soil of his fields with quick lime (calcium oxide), slaked lime (calcium hydroxide), or chalk (calcium carbonate) under certain soil conditions.
If the soil is too acidic, with a low pH, adding lime can help to neutralize the soil and raise the pH to a more suitable level for plant growth. This is because lime is alkaline and can react with the excess H+ (aq) ions in the soil, effectively removing them and increasing the soil’s pH.
Additionally, if the soil is deficient in calcium, adding lime can provide a source of this essential nutrient, which is important for plant growth and development. Calcium also helps to improve soil structure by promoting the formation of stable aggregates, which can improve soil aeration, water infiltration, and root penetration.
