There is surely an expectation that
farmers always talk about the weather…and it’s true, we do! We check three different weather forecasts
daily and plan our work schedule accordingly. The one thing we can say about
the weather we’ve had this summer is that it has been pretty consistent….
consistently Hot & Dry! In fact, I think records have been set for both
temperature and rainfall…or lack thereof. According to the National Weather
service, many parts of southern Wisconsin are now classified as being in a D4
drought given the lack of rain for three months. Thankfully, on Tuesday morning
of this week we woke up to the most glorious sound…. RAIN! We received
three-tenths of an inch, and while that isn’t that much, we were grateful for
every drop!

Checking the "benchmark" point for one of our irrigation sites |
The good news is that the dry
weather greatly decreases disease caused by wet foliage. The challenge is to get enough water to keep
crops growing. We have seven irrigation permits from the Wisconsin DNR to pump
surplus water from the North Fork of the Bad Axe River and two feeder streams. We
have very strict rules to follow when pumping and a “benchmark” water level
below which we would NOT be able to pump.
Fortunately, the underground aquifer system here is very stable and our
benchmarks have remained well above the cut-off! In many states, including
parts of Wisconsin and Minnesota, the underground aquifers have become depleted.
If this severe drought were to continue for several years, that picture may
change in our area as well. At this point we are pumping surplus water at very
low rates, not measurable depth from water run-off to the gulf. Without our ability to irrigate from surplus
water, we would be having a very different year. In years like we are experiencing now,
irrigation is the difference between having or not having a crop.

We are also
very much aware of the benefits we are reaping now from the many years we have
invested in building organic matter in our soil, which increases water holding
ability. As a result, we have been blessed with not only crops, but excellent
crops! Additionally, I’d like to acknowledge and extend my gratitude to Manuel
Morales and Jose Antonio (our two main irrigation guys) who have worked hard, long
hours to try to keep up with our crops’ water needs.

Throughout the summer we’ve had
several extreme heat waves with temperatures in the 90’s and even some days
that have topped 100 degrees! Extreme
temperatures presented us with some extreme challenges. In some crops,
including melons, peppers, and tomatoes, we have observed that the plants did not
set fruit during those extreme periods of heat. We can clearly see a gap
between early set fruit and late. It’s really strange to observe healthy, lush
plants with no disease that have a greatly reduced production of ripening
fruit. The high heat days were also a
challenge for our production schedule and harvest crews. We always schedule
harvests for greens in the morning when it’s a little cooler. This strategy proved to be essential at times
when plants were wilting in the afternoon heat! We also had to be cognizant of
the impact extreme heat has on the health of our field crew. Even though our
crew has a generous supply of drinking water in the field, there were several
days when we started late and ended early to the benefit of the crops, but also
to maintain the health of our crew members.
There were even several days when we had to cease harvests during the
heat of the day, and we started the workday an hour earlier so as to maximize work
in the cooler parts of the day. Thankfully,
we invested in air conditioning units for all of our employee housing several
years ago, so they have a cool house to retreat to and get a good night’s
rest.

Using sprinklers to water a new seeding of fall storage turnips so they'll germinate! |
We are now in the busy transition
between summer crops and early fall crops. We have made some adjustments to our
preseason plan, i.e., later planting in anticipation of warmer late summer and
early fall temperatures. Every direct seeding and transplanted crop we’ve planted
has had to have immediate water to germinate and survive. A very challenging task! We have mostly been successful as your boxes
reflect. Our fall crops which have required irrigation from start to finish but
are looking good! It has been a strange and challenging year for sure! We have
invested in more irrigation equipment, gained three new irrigation permits, and
we’re currently in the process of setting up a new well that we’ll be able to
use for irrigation. Despite the
investment in time and resources, our efforts have proven to be a life saver!
We have good looking fall crops
including lettuce, spinach, radishes, beets, carrots, parsnips, and turnips. We
hope to finish winter squash harvest this week and we’ve already started
harvesting what I consider to be possibly the best rutabaga crop ever! All of these crop outcomes were achieved only
because of timely irrigation. We are now
in the overlap of finishing up harvest of late summer crops i.e., peppers and
tomatoes whilst we are initiating harvest of our fall crops. It is an extremely busy time of the season and
it’s been a challenge to find space in your CSA boxes each week for all the
vegetables we have available!

Our Fall Harvest Party is coming up
on October 1st and we hope you’ll plan to join us! We have some nice-looking pumpkins for you to
choose from this year as well as other crops we’re excited to share with
you! This year we planted the pumpkins
in a trial field that we did as no-till, so you’ll have the opportunity to see
this farming strategy up close, complete with some hearty vetch cover
crop! As always, we thank you for your
continued support of our farm and hope you’ve enjoyed the season so far. We still have more exciting crops to send
your way, so get ready for jicama, sweet potatoes, Brussels sprouts and more!
