Project Update: Whitman County Cover Crop Symposium

The first annual Palouse Alternative Cropping Symposium was held on Friday, February 23rd in Pullman, WA.

Alternative Cropping Systems Symposium

The event was a great success with 80 people in attendance and six fantastic presentations from local growers who are experimenting with cover crops and cover cropping and grazing. In addition to the presentations the program included an interactive poll that addressed where growers get most of their information, soil health on the farm and what barriers exist for trying cover cropping. This event was the first of three Alternative Cropping Symposiums that will be facilitated by the Palouse Conservation District over the next couple of years. The goal of the symposium is to connect growers in the region that are experimenting with cover crops and to provide a forum for peer to peer education. This event was made possible by a grant through the Washington State Soil Health Committee and through donations from our generous sponsors. Sponsors for the symposium included: Pacific Northwest Farmers Cooperative, Palouse Conservation District, OTT Hydromet, Northwest Farm Cred Services, Viterra, Spectrum Crop Development, Clearwater Seed, Spokane Community College, Pearson Farm and Fence, Spray Center Electronics, Roots of Resilience, and Rainier Seeds.

NASA and the Washington State Soil Committee Agree Biochar are “Superstars”

In an article on the Daily Press website, NASA Langley scientist touts biochar: as an ‘environmental superstar.’

From the article:

“Biochar can be made from common organic waste material — from chicken and cow poop to sticks and brush from your yard. It can make environmentally unfriendly synthetic fertilizers obsolete. It can trap nutrient runoff before it pollutes places like the Chesapeake Bay. It can even filter out toxic heavy metals from water.”

The Washington State Soil Health Committee has funded two grant projects featuring biochar. One of the biochar projects is in San Juan County and the other is in Mason County. Below are the summaries of each project.

San Juan Conservation District:
Continuation of biochar project begun in 2016. Following up on the original six-farm test plots, in which biochar was added to soil, the yield will be evaluated in the spring of 2018. In addition to the test plots, biochar kilns were designed and provided to forest landowners on each of the four ferry-served islands. Workshops were offered on each island to demonstrate how to make biochar from forest waste. Online instructions are available for making biochar at home.

Biochar was added as an alternative to the slash burns in the County’s draft Solid Waste Management Plan.

The San Juan Conservation District also starts a new three-year project to introduce no till-direct seed practices to the county, including use of cover crops to improve soil health and limit use of chemicals.

Mason County Conservation District:

The goal is to fill the knowledge gaps on the effects of biochar in the Mason County region. The project will involve measuring the effects of biochar on the balance of pH, the retention of nutrients, the amount of soil microorganisms in local soil types, and crop yield.

Cover Crops in Low Rainfall Wheat Fallow Regions of Eastern Washington

Following a National Forum on Cover Crops and Soil Health, producers became interested in conducting on-farm demonstrations to improve soil health through cover crops.

Washington State Soil Health Committee Grant Recipient Presents at Cropping Conference

One of the 2017 Washington State Soil Health Committee grant recipients presented at the Pacific Northwest Direct Seed Association’s 2018 Cropping Systems Conference Program in Kennewick, WA.

The Palouse Rock Lake Conservation District received a grant to purchase four, 48 inch AquaSpy Soil Probes. Additionally, they purchased a two-year subscription for a cloud storage service. The probes will upload data every 15 minutes via a solar powered on-site apparatus.
The purpose of the grant was to document measured changes in soil moisture, temperature and conductivity every four inches to a soil depth of 48 inches. This will be during a fallow season and after wheat winter was planted in the follow in the fall.
The equipment will document changes through the harvest of 2018.

Tardigrade Are Soil Stars that Can Survive in Space

This interesting article mentions one of the soil stars, the Tardigrade, which has survived space travel. In fact, 68% Tardigrade came back to Earth alive after being launched into space without spacesuits!
Here is the excerpt about them from the article on alien microbes:
“Little, if anything, is (publicly) known yet about the actual characteristics of the “alien” bacteria. The fact that they were found on the outside of the ISS, in low-Earth orbit, is intriguing, but nothing conclusive can be said until it can be determined they didn’t originate from Earth itself. There are many different kinds of microorganisms on Earth, and it is possible that some could get lofted into low-Earth orbit. They are already known to exist in the upper atmosphere and it’s also known that at least one type of microorganism can survive in space itself for some periods of time – tardigrades (water bears). In 2007, some living tardigrades were sent into space on the outside of a FOTON-M3 rocket for ten days by European researchers. 68 percent of them survived the trip, including coming back to Earth. Perhaps there are some other tiny earthly bugs which could do that as well.”

Washington State Soil Health Project Reports 2017

These are the first reports for the eight new contracts for 2017-2020 and for the continuation in 2017 of the first round of projects, which received additional funding. The results are encouraging and, in some cases, fascinating. By demonstrating positive outcomes, these results will promote better soil practices in our state.

Palouse Rock Lake Conservation District:
A new project to measure and compare moisture retention in cover crop fallow and direct seed fallow.

This study is a home run. By comparing moisture retention every four inches up to 48” in side by side cover crop fallow and direct seed fallow, the study has these results so far:

  1. No net loss of moisture in cover crop fallow as compared to direct seed fallow
  2. Decrease in soil temperature in cover crop fallow, which benefits soil organisms
  3. Suppression of weeds without herbicides
  4. Reduction of soil compaction, which enhances moisture absorption and retention
  5. Reduction in soil erosion
  6. Early signs of possible increase in yield

San Juan Conservation District:
Continuation of biochar project begun in 2016. Following up on the original six-farm test plots, in which biochar was added to soil, the yield will be evaluated in the spring of 2018. In addition to the test plots, biochar kilns were designed and provided to forest landowners on each of the four ferry-served islands. Workshops were offered on each island to demonstrate how to make biochar from forest waste. Online instructions are available for making biochar at home.

Biochar was added as an alternative to the slash burns in the County’s draft Solid Waste Management Plan.

The San Juan CD also starts a new three-year project to introduce no till-direct seed practices to the county, including use of cover crops to improve soil health and limit use of chemicals.

Underwood Conservation District:
Completion of original 2015-2016 project to monitor soil moisture in test plots in an orchard, using a control plot, a plot with compost, and a plot with compost and mulch

Results so far show no significant difference in moisture. We are waiting to hear if there is any difference in productivity (yield). We have questions about the 2017 workshop: how may attended, who were the presenters, and what did they present?

Washington Environmental Council:
Continuation of Nisqually Community Forest project which aims to create a template for sustainable forest practices in Pacific Northwest forests.

  1. The project has linked sustainable forest practices with improvements in both water quality and quantity
  2. DOE’s Clean Water Revolving fund was changed to allow sustainable forest projects including forest land purchases
  3. First certified Carbon Project with 520 acres saved from clear-cutting with Microsoft buying the carbon credits
  4. Set up protocol and step-by-step process for creating and selling carbon credits to offset the cost of land purchases
  5. Demonstrating that by growing trees longer, e., longer harvest rotations, the forest is more resilient and stores more carbon over time; older forests also provide better wildlife habitat

    Whitman Conservation District:
    Experiments with various cover crops in the Palouse to identify those best for fall and for spring and to determine whether pelletized compost adds extra yield or other ecological benefits. This will be evaluated in the spring of 2018.

Washington State University: Soil Health Field Day
Soil Health Field Day in Davenport at the experimental farm. Well attended with dozens of farmers and conservationists. Highlighted soil differences between no-till and conventional test plots.

Washington State University:
First year of three-year study of soil characteristics in irrigated agriculture in Eastern Washington.

  1. 60 soil samples were studied from 30 growers to establish a baseline.
  2. Some of the results were surprising, for example, that the amount of soil fines was inexplicably low in many sites.
  3. Several “exemplary soils” were discovered, which were also surprising. More research will be done to discover the secret of those exemplary soils
  4. This study includes a process of evaluating which soil health measurements are of value, and which are not.

Everything Soil Workshop at the Wilke WSU Research Farm

It was so exciting to see such a nice turnout for the “Everything Soil” workshop at the Wilke WSU Research Farm this June. Attendees and speakers from several different WSU programs explored issues surrounding micronutrients, pH, legumes and even satellite imagery for soil assessment.
