Agricultural lime, also called aglime, is a soil additive made from pulverized limestone or chalk.
The primary active component is calcium carbonate.
The effects of agricultural lime on soil are:
  • it increases the pH of acidic soil (the lower the pH the more acidic the soil); in other words, soil acidity is reduced and alkalinity increased
  • it provides a source of calcium and magnesium for plants
  • it permits improved water penetration for acidic soils
  • it improves the uptake of major plant nutrients (nitrogen, phosphorus, and potassium) of plants growing on acid soils
