Follow the Dirt
This has nothing to do with
politics. I’m talking about the real stuff, the soil we grow things in.
Do you remember this: “Our soils are at risk. Our future is
eroding. It is time for action." It was written almost thirty years ago by
Senator Herb Sparrow, the chair of a senate committee that studied soil erosion in Canada. He found it everywhere in the country
where the plow had broken through sod.
PEI is essentially a large farm,
broken up by bedroom communities,
small cities and towns. We live very closely together here, so we’re
much more aware of eroding soils.
We see it clearly mixed in, or on top of fresh white snow, we see it in ditches
and waterways in the Spring when the water starts running.
It takes between 300 to 500 years
to produce an inch of soil, but it can be lost very quickly. At it's worst 10
tons of soil per acre moves from bare fields in a wet spring. It's the fine
particles and organic matter that get lost first. Both are essential to
productivity. Even in strict dollar terms, hundreds of dollars of
nutrients leach from fields, and end up in waterways fertilizing sea lettuce
and other algae which cause the anoxic rivers we see during the summer. None of
this is good.
Many farmers take steps to slow
down this erosion, planting cover crops in the Fall, or spreading straw to
lessen the impact of moving water, but why are so many fields still bare going
into the winter?
A few things: the Russet Burbank
potato, that beautiful, versatile mainstay of the industry takes 130 days and
more to mature which pushes harvest well into October and November, no time to
plant a cover crop. Plant breeding is working on earlier season varieties with
similar characteristics, that can’t come too soon. It’s the same issue with soybeans,
which are becoming the newest go-to crop. It gets harvested late in the Fall
too.
Fall plowing is something farmers
have more control over, they can do it or not. The temptation is to do this
work in the Fall because fields with sod or hay need time to break down the
organic matter, and time is often in short supply in a wet cold Spring. It’s one of these things that needs to
be tackled like smoking or drunk driving, make it something that farmers feel
they shouldn’t do. Maybe the risk and cost of waiting to plow until the Spring
could be lessened with an ALUS payment, or included in what’s covered with crop
insurance, which already looks at yield and quality as a benchmark for a
payout.
Ferndale farmer Ranald MacFarlane dared talk about these
things publically in a television news story recently (Ranald is no stranger to
controversy, and the media, at least, loves his strait talk about difficult
issues). He included himself as
part of the problem, and said he had to change the way he does things, and so
do other farmers. I think
he’s right. Herb Sparrow was right
thirty years ago.
