results from their excretion of large amounts of insoluble
polysaccharides with adhesive qualities. These substances stabilize
soil particles and bind them into water-stable aggregates. An
increase in water-stable aggregates increases soil pore size and
distribution. The changes in soil quality improve soil oxygenation,
water infiltration, and root distribution and decrease erodibility.
The rooting depth of rangeland soils at the location where
ectomycorrhizal fungi were first discovered increased from 2-3 inches
to 18-24 inches after seven years of management with the twice-over
rotation system.

><><><><><><><><><><><><Ted, It could be they're more innovative now
at these higher than usual cattle prices!!! Thanks for the info
though.
    I don't think farmers will switch to AACT until it is affordable
(whatever that means). Many of them are only farming now (ie have
cash flow) cause they can grow large numbers of bushels per acre
which keeps the price low enough to qualify for government subsidies
which keeps prices for raw materials low low low for the large food
processors. Amazing how that works. Anyway cattle prices are higher
than usual now.Dennis
