Expand is a combination of the Latin words ex-, meaning out, and pandere, to spread. The idea of spreading out was always there, though the current idea of something actually becoming larger was first recorded in the mid-17th century.
Aragonite and calcite are two minerals formed from calcium carbonate (CaCO. Lime (calcium oxide) is produced by heating limestone or seashells (calcium carbonate). The chemistry of calcium carbonate is similar to that of sodium carbonate and potassium carbonate except that calcium carbonate is not soluble in water.
Lime. Lime is an alkaline substance that raises the pH of the soil. Many soils have naturally occurring lime -- especially if they are highly alkaline -- but those that donât benefit from adding lime.Most lime is calcium carbonate (CaCO3), and is often called agricultural lime or ground limestone..heir composition depends on such factors as whether they are composed primarily of sand, clay or loam, on how much of the three main plant nutrients -- nitrogen, phosphorous and potassium -- they contain, and on whether their soil is acid or alkaline. Lime is used to affect this last factor by raising soil pH.
