Lime and liming / RHS Gardening

Liming garden soil reduces the acidity of the soil by increasing the pH level. Plants can’t get the nutrients they need from soil that is too acid, and some materials such as aluminium can be at toxic levels in very acid soils. The pH level is a number that describes how acid or alkaline a soil is and from this it is calculated how much lime is needed to reduce acidity.Lime (material) - Wikipedia,Lime is a calcium-containing inorganic mineral composed primarily of oxides, and hydroxide, usually calcium oxide and/ or calcium hydroxide. It is also the name for calcium oxide which occurs as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. The word lime originates with its earliest use as building mortar and has the sense of sticking or adhering.
