With high tunnel systems, no summer is too short or winter too cold because high tunnels offer:

Season Extension

  • Extend the growing season
  • Improve plant quality and soil quality
  • Reduce nutrient and pesticide transportation
  • Improve air quality through reduced transportation inputs
  • Reduce energy use by providing consumers with a local source of fresh produce

High tunnels protect plants from severe weather and allow farmers to extend their growing seasons – growing earlier into the spring, later into the fall, and sometimes, year-round. And because high tunnels prevent direct rainfall from reaching plants, farmers can use precise tools like drip irrigation to efficiently deliver water and nutrients to plants. High tunnels also offer farmers a greater ability to control pests and can even protect plants from pollen and pesticide drift.

A number of soil health practices can be used in high tunnels, including cover crops and crop rotations, which also prevent erosion, suppress weeds, increase soil water content, and break pest cycles.

Perhaps the best thing about high tunnels is that they help farmers provide their communities with healthy local food for much of the year – food that requires less energy and transportation inputs.

MORE on NRCS High Tunnels

This is a reminder for small farms in our region to remember that the NRCS is there to help you with many sustainable farming initiatives including helping with acquiring High tunnels to increase your production and seasonal production.
GRIZZLY HILL High Tunnel KITS has supplied several of these units to farms and we encourage everyone to talk to the NRCS for information on this and the many other types of assistance they offer- Last year- very few farms signed-up with the NRCS for this service and this year it is never too soon to start your paperwork and initiate contact with the NRCS in Grass Valley. Namely-
* Helping with High-tunnel acquisition costs
* Help with Organic Certifications fees
* Energy conservation on your farm
DAVIS, Calif., —The U.S. Department of Agriculture's Natural Resources Conservation Service (NRCS) is accepting applications for special conservation initiatives funded through the Environmental Quality Incentives Program (EQIP) to help producers conserve energy, address resource concerns on certified organic operations or those transitioning to organic production, and achieve a number of other environmental benefits.

NRCS is offering EQIP funding for three special initiatives, including:

* On-Farm Energy Initiative (helps producers conserve energy on their operations);
* Seasonal High Tunnel Initiative (helps producers install high tunnels designed to extend the growing season into the cold months, improving plant and soil quality and reducing nutrient and pesticide transport); and
* Organic Initiative (helps producers to install conservation practices on certified organic operations or those working toward organic certification).
"These special initiatives offer producers a variety of options to conserve natural resources while sustaining production on their lands," said California State Conservationist Carlos Suarez. "We're urging producers to contact their local service center as soon as possible to be considered for this year's funding. Eligible producers with a conservation plan for their operation receive priority for financial assistance."

For additional information, eligible producers are encouraged to contact their local NRCS Service Center. Service center locations and more information on the programs can be found at
