Popis: Based on topographic field data, an argument is advanced that Soil houses ~2.1 x 1024 taxa and supports >99.9% of global species biodiversity, mostly Bacteria or other microbes. Contradictory claims that Soil is home to only a quarter of biota while Ocean harbours 80–99% of Life on Earth are both dismissed. Earlier guesstimates of 8.8 million taxa (2.2 million or 25% marine), of 1–6 billion, or over a trillion species worldwide are likely underestimations. Recent studies show >1012 microbial OTU (just 1010 or 14 and speculated as high as 1023 species. Scaling of simple topsoil samples herein ups total to 2.1 x 1024 or 20x. Biomass at 2 x 10-13 g/cell of 2.1 x 1030 soil cells = 4 x 1017 g or 400 Gt (with 200 Gt Carbon, 48 Gt Nitrogen). An Addendum estimates microbes in gut of two key soil taxa: Megadrile earthworms (1021–1030 cells) and termites (1022–1023 cells) that strictly add to Soil’s totals. Although ranges are large, it is unclear how much 65 x 1015 earthworms contribute to Earth’s soils count of ~2.1 x 1030 cells.
