Chalk

Carbonate of lime, contains, when pure - Carbonic acid .... 45

Lime.......55

But as it usually occurs it contains about twenty-four per cent, of water, and five per cent, of silica (flint), alumina (clay), and oxide (rust) of iron. After these deductions it will be apparent that if fifty tons of lime be applied to land, it will be equal to more than one hundred of chalk, a subject worthy of consideration when it has to be conveyed from afar. Chalk is usually employed in large quantities to improve the staple of a soil. It makes heavy soils less retentive of moisture, and light sandy soils more retentive. On wet sour lands it neutralizes the acids which render them unproductive. Some chalks contain phosphate of lime, and this being a constituent of all plants, such chalk is to be preferred. Some contains a large proportion of carbonate of magnesia, which is less beneficial.
