Here, we review SOC levels of … Rocks erode or weather over a long period of time, mainly by water and wind, and their sediments are transported downstream. These sediments continue to break apart into smaller pieces until they become fine grains of sand. The type of rock the sediment originated from and the intensity of the environment give different compositions of sand. The most common rock to form sand is granite, where the feldspar minerals dissolve faster than the quartz, causing the rock to break apart into s…
WebbSandy soil retains less water than other denser soils such as clay. It tends to dry out quickly most of the time, but if it lies on top of a rocky layer, it can become waterlogged because the layer does not allow the water to drain out. If the soil lies on rock, it may be necessary to dig drainage ditches to avoid plants becoming waterlogged.
