Farmer-Led Trials Program Spotlight: The Woven Trifecta
Testing the Impact of Anaerobic Ferments on Crop Health
Written by Mary Hathaway, OFRF’s Research & Education Program Manager, and Samantha Otto, FLT Program participant
Samantha Otto is the founder and farmer of The Woven Trifecta, a 10-acre farm in western Michigan. Currently in transition to organic, the farm focuses on diversified vegetables for a CSA, local farmers market, as well as farm-to-school sales throughout the school year. Samantha raises Jacob sheep for fiber as well as assorted poultry for meat and eggs. The livestock is rotationally grazed on just over 3 acres of pasture, with 2 acres of no-till beds in production.
Samantha has a decade of hands-on farming experience and is a graduate of Michigan State University’s Agricultural Technology program. Since she started the farm, her primary focus has been on cultivating no-till organic vegetables and cut flowers. But as a curious farmer, she is continuously exploring innovative approaches to sustainable agriculture. Last year, as a participant in the Midwest GRIT program, she began integrating grains into her system, and she has also recently incorporated livestock into her rotations to create a closed-loop system to help improve soil fertility.
From Waste Product to Resources: Building Fertility and Reducing Reliance in Off-Farm Inputs
One of the main goals of The Woven Trifecta is to reduce reliance on off-farm inputs, and to transform the farm waste products into a resource. Samantha has experimented with different anaerobic fermentation, and was interested in scaling up and fine-tuning its use as a soil amendment. She is particularly interested in incorporating waste from her livestock and compost into anaerobic ferments to improve soil fertility and plant health.
With the help of OFRF’s Farmer-Led Trial (FLT) Program, Samantha hopes to understand how anaerobic ferments impact the health of her crops. When considering which vegetable to test, the team landed on artichokes – a promising crop that her CSA members love and that has yielded well in past seasons. As a long-season vegetable with a short harvest window, the Tavor Artichoke was an ideal crop to trial.
Farm Trial Plan
To answer Samantha’s question, ‘Does an anaerobic compost tea impact yield or plant nutrition in artichokes?,’ she will weigh all harvested artichokes from each plot. Marketable artichokes will be weighed and counted separately. In addition to weights, leaf tissue samples will be collected prior to flowering stalk emergence. 10 representative samples will be taken from each plot, with one leaf collected per plant.
There are two treatments in the trial: a control with no ferment spray, and the anaerobic ferment foliar drench. Samantha will plant in 8 plots to provide sufficient replication. The trial is in a 30′ x 90′ space, in 3′ wide no-till beds, with each row containing 10 plants spaced 36’ apart. Buffer plots will be added on each side, planted with sunflowers.

The recipe for the anaerobic fermentation is 60/40 with vegetation scraps and rabbit manure. Samantha brews a fresh batch every two weeks, beginning in early June and applies the fermented drench application biweekly. A 5-gallon bucket will be suitable for each batch.
Recipe for Anaerobic Fermentation Fertilizer
Using 5-gallon buckets, mix:
- 60% vegetation scraps from on-farm and/or compost club program
- 40% manure from our rabbits.
- 4 cups of soil.
These will be well mixed, with scraps being chopped into small pieces, and will fill about 3/4 of the 5-gallon bucket. This mix will then be submerged in water (from well), covered with a lid and stored in the pump shed. The bucket will be fitted with a fermentation lid with spout to release any built-up gases over the course of the fermentation process.
Ferment will be checked at 7, 14, and 21 days; ready to use at 21 days. Solids are then strained, and the liquid is bottled for use.
Application: 1 part recipe to 20 parts water every 14 days, and apply it as a soil drench via backpack sprayer.
Samantha is excited to see how the ferment impacts the health and yield of her plants. The process of testing her application of the anaerobic ferment is something she hopes can impact her farm system, and possibly provide sustainable answers for other small farms like The Woven Trifecta.

“Working with OFRF has been an amazing opportunity for our farm! Closing the loop in our production is a long-term goal of ours, and this project has provided the opportunity to take the time to explore a potential process for making that happen. It has been especially delightful to work with OFRF on creating the foundation of our project, making a once-intimidating idea very fun and feasible to trial! It has been a thrill to find on-farm solutions that support both our livestock and vegetable production. While we are a ways away from harvest, our on-farm ferment is visually showing benefits in our test plot. I look forward to collecting further data as the season progresses! This data will help us make decisions on how to incorporate ferments in our wider production in the future so that we can continue to grow beautiful, healthy, thriving vegetables for our community.”
