Lime soils are pretty common, but what is chalky soil? Continue reading to learn about gardening in chalky soil. What is Chalky Soil? Chalky soil is comprised mostly of calcium carbonate from sediment that has built up over time. It is usually shallow, stony and dries out quickly. This soil is alkaline with pH levels between 7.1 and 10.
Clay soil can feel like a curse to gardeners and can be difficult to plant, shovel or till. When it is compacted, it is nearly impossible to break up using only physical strength. Different machinery may be able to provide a better option for tilling and shoveling the clay soil.
Loam is soil composed mostly of sand (particle size > 63 µm), silt (particle size > 2 µm), and a smaller amount of clay (particle size < 2 µm). By weight, its mineral composition is about 40–40–20% concentration of sand-silt-clay, respectively.
Peat often stains the water yellow or brown due to the leaching of tannins. Water filtration. Peat is used in water filtration, such as for the treatment of septic tank effluent and as for urban runoff. Balneotherapy. Peat is widely used in balneotherapy (the use of bathing to treat disease).
Silt and clay contribute to turbidity in water. Silt is transported by streams or by water currents in the ocean. When silt appears as a pollutant in water the phenomenon is known as siltation. Silt, deposited by annual floods along the Nile River, created the rich, fertile soil that sustained the Ancient Egyptian civilization.
