WebCalcium deposits, or calcification, can occur when calcium builds up in your body. This buildup of calcium can harden in your tissues, organs or blood vessels. When this happens, your body's normal processes may not run correctly. Your bones and teeth use almost all the calcium in your body (about 99%). Leaching is what happens when water removes soluble nutrients from a soil over time. Calcified soils ordinarily exhibit little leaching, although improper land management can lead to substantial leaching and thus the loss of soil fertility. Deserts with calcified soil profiles can be fertile if highly irrigated, … See more In warm, dry grasslands, soil bacteria and fungi rapidly convert decaying organic matter into humus, so the upper layers of the soil become rich. Burrowing animals mix this organic … See more A laterite soil profile often forms in hot, moisture-laden tropical regions, where chemical processes rapidly break down rock to furnish more parent material for the soil.
