Fungi in Agriculture
This is a great article about using beneficial soil fungi to reduce fertilizer in agriculture.
Although this article mainly covers mycorrhizal fungi, the principle of using beneficial soil fungi remains the same.

Fungi Reduce Need for Fertilizer in Agriculture
May 26, 2011 — The next agricultural revolution may be sparked by fungi, helping to greatly increase food-production for the growing needs of the planet without the need for massive amounts of fertilizers according to research presented May 23 at the 111th General Meeting of the American Society for Microbiology in New Orleans.
Sanders studies mycorrhizal fungi, a type of fungus that live in symbiosis with plant roots. When plants make symbioses with these fungi they tend to grow larger because the fungi acquire the essential nutrient phosphate for the plant. Phosphate is a key component of the fertilizers that fueled the Green Revolution in middle of the 20th century that made it possible then for agriculture to keep up with the growing global population.
“In most tropical soils plants have enormous difficulty in obtaining phosphate and so farmers have to spend a huge amount of money on phosphate fertilizer. Farmers have to add much more fertilizer than in temperate regions and a very large amount of the cost to produce food is the cost of phosphate,” says Sanders.
Phosphate reserves are being rapidly depleted. Increasing demand for the nutrient is driving up prices and some countries are now stockpiling phosphate to feed their populations in the future, according to Sanders.
While mycorrhizal fungi typically only grow on the roots of plants, recent biotechnological breakthroughs now allow scientists to produce massive quantities of the fungus that can be suspended in high concentrations in a gel for easy transportation.
Sanders and his colleagues are currently testing the effectiveness of this gel on crops in the country of Colombia where they have discovered that with the gel they can produce the same yield of potato crop with less than half the amount of phosphate fertilizers.
“While our applied research is focused on Colombia it could be applied in many other tropical regions of the world,” says Sanders.
