Basalts give strong rich clays, with a considerable amount of lime and some phosphoric acid. Limestone soils are often shallow and warm, and yield a very nutritious vegetation. Some limestones yield a small percentage of phosphoric acid, and the soils formed from them arc in consequence greatly enriched. Soils derived from limestone are sometimes deficient [...]

Some limestones yield a small percentage of phosphoric acid, and the soils formed from them arc in consequence greatly enriched. Soils derived from limestone are sometimes deficient in lime, for this is removed as a bicarbonate, and only the clayey impurity of the lime is left. Silurian grits and shales yield soils which vary ... Read More
