Soil clay loam that begins at 43% water by weight to a field capacity of 22% is six days, whereas a sand loam that is flooded to its maximum of 22% water will take two days to reach field capacity of 11% water. The available water for the clay loam might be 11% whereas for the sand loam it might be only 8% by weight. The above are average values for the soil textures as the percentages of sand, silt and clay vary. Water moves through soil due to the force of gravity, osmosis and capillarity. At zero to one-third bar
Parent material eventually settle near the mouth of the river. Lake deposited parent material is called lacustrine parent material. Beach ridges may be present where glacial lakes once washed up sand. Lacustrine material is well sorted and fine-textured, having finer silts and clays. Soils formed from lacustrine parent material have low permeability in part because of this high clay content. Ocean deposited parent materials, called marine sediments, are collections of material that have been carried by rivers and streams to the ocean and eventually sink to the bottom. Such materials can vary in texture. Collections of large rock fragments that have traveled
