Limestone is primarily composed of calcium carbonate but many contain small amounts of clay, silt and dolomite. Dolomitic limestones come from natural deposits which contain both calcium and magnesium carbonates. The magnesium content of limestone is especially important where soils are deficient in this essential plant nutrient.

It is most likely some carbonate rock, if not limestone exactly. Old Indian mounds are usually covered with hundreds of volunteer Sabals as well, even when they are absent on surrounding terrain. I suspect it is due to the high shell content in the soil. Sea shells contain Calcium carbonate (CaCO3), the same mineral that makes up limestone.

Among these adsorbents, limestone proved its capability in removing more than 90% of heavy metals (Aziz et al. 2004). High purity limestone can offer a high performance of adsorption due to the high carbonate content in the limestone media. In addition, the surface charge of adsorbent also contributes to heavy metal removal (Aziz et al. 2004).

A manganese deficiency in plants often results from soils too rich in organic matter or with high pH levels. Manganese is critical for synthesizing fatty acids, the regulation of the carbohydrate metabolism and the energy budget. An adequate supply of manganese is required to decrease nitrates within the plants.

There are four types of carbonate-based limestone that are available. Calcite is pure calcium carbonate (CaCO 3, 40 percent Ca). Calcitic lime is composed of mostly CaCO 3 (> 30 percent Ca) with some MgCO 3 (<5 percent Mg). Dolomitic lime contains less CaCO 3 (<30 percent Ca) and more MgCO 3 (>5 percent) than calcitic lime.

manganese processing, preparation of the ore for use in various products. Manganese (Mn) is a hard, silvery white metal with a melting point of 1,244 °C (2,271 °F). Ordinarily too brittle to be of structural value itself, it is an essential agent in steelmaking, in which it removes impurities such as sulfur and oxygen and adds important physical properties to the metal.

MANGANESE REACTIONS IN SOILS In soil, manganese occurs as exchangeable manganese, manganese oxide, organic manganese, and a com- ponent of ferro-magnesian silicate min- erals. The manganese ion (Mn++) is similar in size to magnesium (Mg++) and ferrous iron (Fe++) and can substi- tute for these elements in silicate min- erals and iron oxides.

Manganese removes oxygen and sulfur when iron ore (an iron and oxygen compound) is converted into iron. It also is an essential alloy that helps convert iron into steel. As an alloy, it decreases the brittleness of steel and imparts strength. The amount of manganese used per ton of steel is rather small, ranging from 6 to 9 kilograms.
