Mark and I recently attended a showing of Dreaming
of a Vetter World, with a
Q&A by Donald Vetter afterwards. If you've never heard of him,
Vetter
is a farmer right up Joel
Salatin's alley who uses long crop rotations combined with
rotational grazing to improve his soil. After decades of this
treatment, Vetter's
soil can soak in up to eight inches of rain per hour while his
neighbors' conventional fields start ponding and eroding after half an
inch in a similar time period.
So what does Vetter do to get such great results? He uses a nine-year
rotation, a third of which involves cows and pigs on pasture. We'll
start with that part --- the soil-building end of the spectrum. After
planting a grass/legume/forb mixture, he utilizes rotational grazing
for
three years, then he tills the rich greenery in.
Next comes the cash crops --- soybeans in year one, corn in year two,
then an Ethiopian land race of barley that his sister company (a
small-scale, organic grain-processing operation) bags up to sell as
bird seed. After a winter of cover
cropping combined with fall and
winter grazing, it's back to soybeans for a year followed by a final
season of popcorn.
Using this rotation, Vetter has added no off-farm inputs for twenty
years and sees annual improvement of his soil. He doesn't even buy
animal feed --- the waste seeds from his
grainary supplement his livestock's dependency on grass. The result is
a beautiful permaculture system that runs smoothly...when combined with
a lot of hard work.
Hi Anna,
Nice to see some real content on your website again :).
Have you discovered Roland Bunch - Restoration of the soil book -- Free pdf?
Same sort of thing but much simpler. Soil gets better and better for at least 40 years.
I will be trying his method this year.
