Dolomite Lime - change the pH of your soil, add calcium too

In clay soils, dolomite lime will enable the clay particles to break up and become more friable, allowing better water drainage. It also enables the nutrients tied up by the pH to be released for use by the plants. Added in combination with organic matter it will improve most soils immensely in only a few years. Used in specific garden beds to ...

Why is Dolomitic Limestone better | Pattison Company

What is Dolomitic Limestone. Dolomitic Limestone has been around for a very long time and has gone through many name changes over the years. Dolomitic Limestone was originally known as "Magnesium Limestone," as it contains high levels of magnesium instead of just calcium. So just about anyone who can use magnesium should be interested in it.

Dolomite Lime – How Garden Lime Can Cause Problems

Dolomite is recommended to correct calcium and magnesium deficiencies. Depending upon magnesium levels, dolomitic lime can often cause more harm and trouble, however, than its initial cost. Excess magnesium is often associated with soil stickiness, crusting, compaction, reduced aeration, and releasing nitrogen from the soil pound for pound.

Dolomitic lime is a preferable soil additive for sandy soils, which have large particles and are unable to hold magnesium or calcium minerals, and do not retain water. Raises pH/neutralizes acidity: pH is the "acidity" of the soil and is measured by the number of hydrogen ions present in the soil.

Sediments and Sedimentary Rocks

Dolomite generally does not form as a primary precipitate from seawater. Instead, dolomite is a product of diagenetically altered carbonate sediments and limestone. The original calcite or aragonite sediment is converted to dolomite soon after deposition by the addition of magnesium ions from seawater passing slowly hrough the pores of the ...

Limestone - Wikipedia

Description. Limestone is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3). Dolomite, CaMg(CO 3) 2, is an uncommon mineral in limestone, and siderite or other carbonate minerals are rare. However, the calcite in limestone often contains a few percent of magnesium.Calcite in limestone is divided into low-magnesium and high ...

Dolostone (Limestone)

The particles of sediment that make up a typical limestone are frequently recognizable as fossil fragments. By contrast, most dolostone is crystalline. Dolostone forms when magnesium in pore water is substituted for some of the calcium in the original limestone, or by direct precipitation.
