The Secret To A New Green Revolution?

Big Picture Agriculture:

Is the fungus Micorrhiza a panacea?
It seems to make possible what might seem impossible, like growing vegetables in the inhospitable saline soils of Qatar. Calling it cheap with huge potential, scientists in Qatar used this naturally occurring soil fungus by mass producing it in labs and then adding it to soil to grow healthy, nutrient rich vegetables like corn, radishes, tomatoes, and also wheat. The crops grown were nutrient rich, like those grown on much better arable land. These plants were grown where salinity was greater than the sea one meter beneath the soil surface.
Micorrhiza, or root-fungus, increases the fruit and flowering of plants while improving soil quality and reducing the need for water and fertilizer. It is organic, natural, and chemical free.
When the right type of Micorrhiza is added to soils, it is capable of reducing water needs by 25 percent. It reduces the need for fertilizer, enables plants to be grown in salty or contaminated soils, and increases the temperature stress tolerance of plants. It does so by working symbiotically with plants. It attaches to the roots and forms root exudates or arbuscules, with finely branched hyphae which allow for an amplified exchange of nutrients between the soil and the plant. It greatly enhances the uptake of phosphorus and it protects the plant roots from disease pathogens. It is possible for a plant with the fungus present on its roots to uptake 100 times as many nutrients as a plant without the fungus. Certain types of Mycorrhiza are also key to storing carbon in the soil.

That is fascinating.  The skeptic in me says this is too good to be true, because it makes the same kind of claims as the witch doctor soil additives that guys pitch at all the farm show, but maybe there is some real potential there.  I'll withhold judgement for now.
