Shale soils are fine-textured and tend to be acidic and low in nutrients â with largeadditions offertilizer, they are farmed. On mountainsides theyoften support mixed forests.Much of the land overlying shale deposits has been ruinedby strip mining, because shale contains Pennsylvaniaâs rich coalbeds.
The lower boundary of peat soil approximately coincides with the depth to which water in the soil descends in summer (from 30 to 50â60 cm, sometimes deeper). Peat soils differ from underlying rocks in their higher coefficient of filtration and greater permeability to water. Two types are distinguished: high-moor and low-moor. High-moor peat soils are formed under conditions in which precipitation provides the required moisture.
