Through a grant from the Department of Ecology and support from the Puyallup Watershed Initiative, we have partnered with WSU to conduct field trials of cover crops and the use of our new Direct Seed-Drill. 163 local farmers have attended these workshops to learn more about how these practices can improve both soil health and local water quality. |
Traditional tilling practices and lack
of cover crops in Pierce County have
created a situation where stormwater
carries soil off of farmland and into
surface water. The loss of topsoil
from the farmland reduces soil
quality and farm productivity. The
soil runoff into streams also impacts
water quality and results in decreased
salmon survival rates. Reducing tillage
through direct seeding improves soil
quality, controls weeds, increases soil
carbon, and reduces fuel usage. Cover
crop practices can provide a weed
suppressing mulch, add organic matter
to the soil, and increase soil fertility.
Taken together, these practices result
in lower costs and better productivity
for farmers, while also creating better
conditions for endangered salmon, a
multi-benefit approach we’re working to
implement across the county.
All of these reasons are why in 2018,
Pierce Conservation District (PCD)
embarked on a cover crop initiative
using a multi-pronged approach. That
year, a Crop Farm Program Manager was
hired to lead the initiative. With funding
provided by the Agriculture Community
of Interest (AgCOI), which is part of the
Russell Family Foundation’s Puyallup
Watershed Initiative, a direct seed
drill and flail mower were purchased
to loan to farmers in lieu of them
purchasing their own equipment.
Cover crop seed varieties and planting
methods were tested through trials
led by researchers at WSU Puyallup-
Research and Extension (WSU Puyallup)
in collaboration with PCD and local
farmers willing to provide land. Funding
was obtained through a WA State
Department of Ecology Centennial
Clean Water Fund Grant to provide
cost sharing financial assistance to
farmers willing to try direct drill seeding
and cover cop installation. That
grant also funded the drill borrower’s
instruction video, a forthcoming cover
crop promotional video, and producer
educational workshops.

In 2019 we expanded those efforts
through additional cover crop trials with
WSU Puyallup, continuation of cover
crop and direct drill seeding financial
assistance to producers, leading to
25 number of farmers implementing
the practice over 371 acres. Also, in
partnership with WSU Puyallup, we
created the annual Cover Crop Round
Table. The Round Table’s goals have
been to network with regional growers
and researchers, share information
on local cover crop successes, and
coordinate research interests and
needs. The Round Table was well
attended by both Pierce County farmers
and by producers from around the
region. A second annual event is already
scheduled for early 2020 and we’re
excited to see this initiative continue to
grow.
