Liming materials. Lime raises pH and is usually added as ground limestone, commonly called 'garden lime'. Hydrated lime (calcium hydroxide), sold for use by builders, can also be used. It is a fine powder, quick acting, but can irritate skin and eyes if not handled carefully.
Also, how much lime is required per acre?
Quantities of lime for lawns are normally expressed in a number of pounds per 1,000 square feet (one acre is 43,560 square feet). For example, a hypothetical-yet-typical application might be 40 pounds of pelletized limestone per 1,000 square feet of grass area you want to treat.
What does lime do for a vegetable garden?
These are not recommended for lawns and gardens. In addition to supplying calcium, lime makes soils less acidic. Acidic soils, referred to by old timers as sour soils, have a low soil pH. Most vegetables, fruits, and ornamental plants grow best when the pH is slightly acidic, between 5.5 and 6.5.
