Organic No-Till Farming Research Initiative: An Update

Under the Microscope at Assawaga Farm
We visited Assawaga Farm in late September to take a peak at how microbes are handling the ‘no-till’ environment up there. For the past 2
years Yoko and Alex have worked tirelessly on their 2 acre intensive farm to ‘push the envelope’ on no-till farming techniques. They are growing a wide assortment of vegetables, incorporating no-till with succession planting, cover crops and holistic farming practices to grow the healthiest food possible.
We took a look at their soil under the microscope and discovered excellent microbial life and soil structure. Below is a movie showing microscopy from one of their beds, growing a cover crop of field peas and oats in a bed that has not been tilled for the past 2 years…
Notice the amount of aggregates, large dark bundles of bacteria, resulting in excellent soil structure.
Yoko and Alex both felt that the microscopy gave them a much better understanding of what is going on inside their soil. They now have a
new set of eyes for soil, and have a greater appreciation for the life therein. Yoko explained how this will change the way they farm: “This will certainly make us think harder about how to treat the microbes, like keeping the soil covered at all times and have as much growing through the year as possible. We’re going to interplant around our main crops, to add diversity and cover as much soil as possible with living plants.”
No-till allows the soil to establish communities of fungal networks, aggregates of bacteria, and a constant stream of nutrient cycling between
plants and microbes. Alex talked about some of the challenges they face with no-till:
“We have a paperpot transplanter that does a great job planting seedlings. When we have residue of, tomatoes and peppers it’s difficult to get the planter through there. It’s much easier to have a newly tilled bed, but the rewards of leaving the roots to slowly decompose and add organic matter and food for the microbes gives us a much healthier next crop, so its worth the extra effort.”
We took another look at soil that was probably the least disturbed over the past two years, the garden bed growing ginger. Amazing how many fungal hyphae have developed in that short amount of time. See this for yourself below:
Fungal hyphae dominate this sample, and fungal dominant soil is preferred by ginger so it’s a perfect pairing of “right crop, right soil biology”.
Alex and Yoko shared with me a photo of one their success stories that came from no-till farming. These basil plants were planted at the same time. The right bed had been bare for about a year, the left bed had residue of celery with basil interplanted between the harvested crop:
The takeaway from our visit to Assawaga is that no-till is working in ways that the microscope can show:
- better soil structure
- more diverse life in the soil
- balance of fungi to bacteria
Our deepest thanks and appreciation for innovations in organic agriculture go to our partners at Assawaga Farm, as we at NOFA continue to explore ways to grow the healthiest food possible.

Advocacy News: May 2026
The Good News: CT Senator Chris Murphy has introduced a bill (bipartisan and bicameral) to increase funding for Agricultural Management Assistance to $30 million and to expand the eligible uses for these funds to include “soil health improvements, composting, implementing organic farming, and food safety certification in addition to existing authorized uses such as water management structure and soil erosion control.” Let’s thank Senator Murphy for introducing this bill!
The Bad News: The Farm Bill passed the House of Representatives on April 30, despite 320 food, farm, and conservation organizations, including CT NOFA, voicing our opposition to a bill that does not fix SNAP, does not support new and beginning farmers, and does not adequately support conservation programs or organic agriculture. Now it goes to the Senate and we need to urge both of Connecticut’s Senators to reject this Farm Bill.
Our Vision for a Future of Resilient, Plentiful, Healthy and Locally-Grounded Farming and Food
In concluding its annual retreat, the Northeast Organic Farming Association Interstate Council (NOFA IC) reaffirms the values that have grounded our work for 55 years.
Our vision is that every person is able to live their life with healthy food, clean water and air, community, livelihood, dignity, and purpose within the means of our life-giving planet. We seek that vision on every level, from our households and farms to our communities, states, bioregions, nation, and world. For that vision to be fulfilled, every person, no matter their origin or circumstances, must have all their basic human needs met without degrading the air, water, soil, ecosystems, and climate which we have been given and on which we depend for our lives.
