Newsletter - Season extension

Local food growers who use season extension may see multiple benefits.  Yields and quality can be improved.  Growers can also be first to market with earlier crops and produce longer into the fall.

Growing in a high tunnel, a.k.a. hoop house, or using other means of season extension come with a unique set of challenges; different pests and diseases, crop rotation, irrigation management, etc.

So, here are some resources and educational opportunities for those looking to add season extension to their farming mix or make improvements to existing practices.

In the news:  Extending Minnesota’s growing season

Resource:  UMN low tunnel strawberries

Research at the West Central Research and Outreach Center has shown great results from low tunnel strawberry production.  Their website features articles on different aspects of the production system as they go through the growing season. 

If you’re interested in this system, I highly recommend the free eBook "Cold climate strawberry farming” featured on this site.

Recorded presentation:  Increasing vegetable production with economical season extension

High tunnels are not the only game in ‘season extension town'.  In this recorded presentation, Terry Nennich, UMN Extension Emeritus, discusses…
  • Raised beds
  • Plastic mulch
  • Row covers
  • Low tunnels

Because it’s hot (especially in a high tunnel!):  Heat illness and agriculture

Work still needs to get done despite how unpleasant the weather may be.  This Penn State Extension article goes over the risks, symptoms and strategies for dealing with excessive heat on the farm.  A few of their tips include…
  • Drink approximately 8 oz. (1 cup) of water about every 15–30 minutes. (Note: Do not wait until you are thirsty to drink water!)
  • Avoid caffeine, alcohol, drugs and large amounts of sugar because they can speed up the dehydration process.
  • If you are a farm owner or manager, educate your workers about the prevention and emergency response of heat-related illnesses. Also observe your employees for heat related problems as well.

That's it for this week, have a great weekend!
