Farmer-Led Trials Program Spotlight: Farmacea
Farmacea Strawberry Trial Explores Sustainable Mulching
Written by Mary Hathaway, OFRF’s Research & Education Program Manager
In the heart of Munith, Michigan, Farmacea, is undertaking an exciting experiment to help enhance their farm systems and design. Run by Mike Lucas and Rollin Baker, the farm’s 31 acres had previously been dedicated to conventional corn production for many decades. Over the past two years, Mike and Rollin have been diligently working to convert about 2 acres into arable, quality land by incorporating leaf mold and other organic materials. As they work to transition their land to certified organic, they are excited and energized to grow healthy, sustainable fruits and vegetables for their community. Mike and Rollin are committed to bringing the land back to life and hope to honor the tradition of Food as First Medicine.
The Strawberry Trial: Plastic vs. Clover
Farmacea’s project is a strawberry trial comparing traditional plastic mulch to a living mulch of white Dutch clover. Their research question is simple but will help Farmacea determine which strawberry planting system will work best for them in the coming years: “Does a living clover mulch produce higher strawberry yields than a plastic mulch?”.
To answer this, they’ve set up six beds. Three beds use the conventional plastic mulch, while the other three are planted with New Zealand White Clover (Trifolium repens) to serve as a living mulch. Both sets of beds include a mix of strawberry cultivars: Earliglow, Chandler, Allstar, and San Andreas, ensuring consistency in strawberry varieties across the trial.
Careful initial planning was essential, focusing on a consistent number and mix of strawberry plants in each bed. Mike and Rollin standardized the beds and timed clover planting, which faced weather-related delays and farm facility damage. Additionally, deer intrusions necessitated the construction of higher fences to protect the crops.
What They’re Measuring
Farmacea will be tracking several key metrics to determine the success of each mulching method:
- Yield: Weight of harvested berries, percent marketable yield, and pint counts.
- Brix: A measure of sugar content in the berries.
- Weed Pressure: Observations and frequency of weeding interventions.
- Photo Documentation: Keeping a visual record of the trial’s progress.
- Soil Testing: Collecting samples to analyze soil health.
Data is being collected consistently over the season, with harvests twice weekly. They plan to document everything from the number of pints of berries to the weight of both marketable and unmarketable yields. Brix levels are being measured to gauge the sweetness of the berries and will ideally be taken at three intervals during the strawberry season.
Why This Matters
Farmacea’s trial is about more than just growing strawberries. It’s about finding sustainable options for weed suppression and improving soil health through practices like cover cropping. They are also interested in decreasing their reliance on nonrenewable resources and preventing microplastic contamination in their soil. Implementing a living mulch strategy is intended to lessen the need for manual weeding, enhance soil structure, and foster an environment that naturally inhibits weeds.

“For too long, the bulk of attention, funding, and resources in the agricultural research world have gone toward so-called ‘conventional’ farming methods. As a result, advances in organic farming practices have stalled and many today consider it an inefficient, outdated, and impractical way to produce food. We couldn’t disagree more. We see participating in a research trial on organic farming to be an important step in turning this tide, and hope that it will lead to better understanding and acceptance of these essential practices.”

Looking Ahead
As the trial progresses, Farmacea will continue to monitor and collect data. Soil tests will be conducted, and observations on weed pressure will be recorded. At the end of the trial, they will analyze the results to determine which mulching method provides the best yields, berry quality, and weed control.
This trial at Farmacea is a perfect example of how farmer-led research can lead to valuable insights and sustainable agricultural practices. By sharing their findings, Farmacea contributes to a broader community of farmers and researchers working towards a healthier, more resilient food system.
