As a later comment points out, in a manner as arresting as the vision it criticises, roots are how plants get their inputs. The soil feeds the plants! - not the other way around.
But, maybe in 500 years they'll have fixed this.
- samatman 14y agoThe actual relationship is more two-way, as plant roots exist in symbiosis with mycorrhizae, providing sugar in exchange for minerals and other micronutrients.
- InclinedPlane 14y agoThis is factually inaccurate. Plants are not built out of soil, they are built out of air and water, the contribution from the soil is comparatively minor. Especially if symbiotic mycorrhiza are in play in which case only a tiny handful of minerals and phosphorous is pulled from the ground. The great bulk of the mass of a tree is cellulose and lignin, and that comes straight out of photosynthesis and from atmospheric CO2 and ground water.
