About Garden Lime Rock Dust
Limestone has been used more extensively for adding soil fertility than any other type throughout modern agricultural history. Agricultural Lime or Garden Lime is composed predominantly of calcium carbonate. Around the world large deposits of these sedimentary stones can be found. They are composed of the remains of ancient sea life that incorporated calcium into their shells and in many cases are surprisingly pure in calcium content.
Agricultural Lime raises and buffers the value of pH in acidic soils helping to balance the availability of other nutrients while also adding the benefit of extended calcium release. We recommend using Agricultural Lime for those needing pH adjustment and additional calcium, a welcome addition to the mineral makeup of most garden soils.
