Plantstones store carbon

This odd looking model was developed based on an example in New Scientist magazine, 5th Jan 2008 "While Others Lock Carbon Away for Years". What the model says is that new strains of wheat and other crops can create a strong amplifying effect on the ability of the plant to create plantstones. They are therefore a potentially important solution to countering CO2 omissions.

Plantstones are created by the plant growing and consuming minerals. Plantstones remain in the soil even after the plant decays. Thus, carbon can be stored in the plant (when it is alive) and afterwards (when it is dead) by virtue of the plantstones it leaves behind. Get this right, and the counteracting effect on greenhouse gases is strong.

Plantstones form as microscopic grains of silican in plant leaves, particularly in grass-based pastures and crops such as sugar cane and wheat. This is refered to as phytolith occluded carbon
