"Industrial-Scale Farming,

Question

Sustainable Path"
by Miriam Horn

The concerns about Roundup-and the crops engineered to resist it-
are well-founded: the combination has been wildly overused, enabling
vast monocultures and breeding resistant weeds. Most organic farmers
make the opposite choice: avoiding chemical herbicides by tilling. But
most soil microbiologists believe that causes greater ecological harm.
"If you till to avoid herbicides, you do massive damage to soil
microbiology," says Justin's mentor, Kansas State soil microbiologist
Charles Rice. If herbicide, used judiciously, "allows you to leave the soil
intact, it is a net environmental positive. We have fields that have been
in continuous no-till for 22 years, using herbicides, with ever more
microbial diversity and life."

That flowering is evident in Justin's soils. His fields are increasingly (like
the prairie) self-contained: holding soil, water and nutrients in place and
building organic matter, fertility and biodiversity where it counts the
most: underground. Among those who regularly track his progress is Dr.
Ray Ward, a legendary soil scientist who runs a private testing lab in
Nebraska. Ward has charted a steady microbial renaissance in Justin's
soils: in total mass, diversity and vigor. Justin's soil carbon, depleted to
near zero by generations of plowing, is now more than halfway to the 4
percent carbon levels in native prairie soils. With another decade or two
l, says Rice, Justin will close that gap.
