Physical properties

Formation & geological history

Formed through the mechanical weathering of underlying bedrock or transported via wind (aeolian) and water (alluvial) deposition. Common in arid or semi-arid climates, these soils are often Holocene to Pleistocene in age.

Uses & applications

Primary use is for agriculture (specifically for drought-resistant crops like the grass pictured), landscaping, and as a stabilizer in construction fill or low-grade mortar.

Geological facts

Sandy loam is considered the ideal soil for many plants because it provides good drainage while retaining enough organic matter to provide nutrients. The quartz grains within the sand are often millions of years old, surviving multiple cycles of erosion.

Field identification & locations

Identify in the field by the 'gritty' texture when rubbed between fingers and the lack of plastic ribboning when wet. Commonly found in coastal regions, river valleys, and desert fringes.
