No Till, No Drill, No Problem: Integrating No-Till Methods into Organic Production Systems
Utilizing cover crops, compost and crop rotations to improve organic no-till crop production will be the subject of a full-day pre-conference on Feb. 17 and three workshops at the Ohio Ecological Food and Farm Association’s (OEFFA) 33rd annual conference, Sowing the Seeds of Our Food Sovereignty, on Feb. 18-19 in Granville, Ohio.
The events will feature Jeff Moyer, the director of farm operations at the Rodale Institute in Pennsylvania, home to the Farming Systems Trial, America’s longest running side-by-side comparison of organic and chemical agriculture.
“No-till farming provides significant benefits by allowing farmers to grow crops without disturbing the soil, reducing erosion while increasing organic matter,” said Renee Hunt, OEFFA’s program director and the event’s organizer. “But because no-till also requires significant use of herbicides, it has not been available to organic farmers, who rely on mechanical tillage to control weeds. With organic no-till, Jeff is pioneering a practice that will allow organic farmers to reap the benefits of no-till and conventional farmers to reduce their reliance on herbicides.”
As manager of the 333-acre research farm, Moyer is an expert in organic crop production systems including weed management, cover crops, crop rotations, equipment modification and use and facilities design. He is a past chair of the National Organic Standards Board, which assists the USDA Secretary of Agriculture and the National Organic Program in developing and implementing standards for organic production.
The pre-conference, “No Till, No Drill, No Problem: Integrating No-Till Methods into Organic Production Systems,” will take place on Feb. 17 from 10 a.m.-4 p.m. Moyer will discuss practical ways to utilize soil fertility to tackle problem weeds, build soil tilth, retain soil nutrients and create biologically active soils.
On Feb. 18, Moyer will be offering three workshops as part of OEFFA’s annual conference. “No-Till Organic Farming” will look at techniques to maximize yields in field crop operations, by reducing or even eliminating tillage.
Moyer will also present “Using Compost in Field Crop Systems.” This workshop will explore how to effectively manage compost applications to improve the health and biological activity of soil in field crop systems. He will also discuss simple tools for producing good compost.
“While 'compost happens,' a good compost operation producing consistently high-quality compost doesn’t. It doesn’t just happen on its own, that is. It takes a fair amount of planning and, like any enterprise, good management,” said Moyer.
During Moyer’s final workshop, “Cover Crops for Soil Fertility,” he will discuss ways to enhance soil fertility through the intensive management of cover crops, drawing on more than 30 years of research looking at the best strategies to increase field crop production using sustainable methods.
The events are featured as part of the state’s largest sustainable food and farm conference, which draws more than 1,000 attendees from across Ohio and the Midwest each year. In addition to Moyer, this year’s conference will feature keynote speakers Woody Tasch and Andrew Kimbrell, more than 70 informative and hands-on workshops, two featured pre-conference events, a trade show, a fun and educational kids’ conference and child care area, locally-sourced and organic homemade meals, and Saturday evening entertainment.
All events are at Granville Middle and High Schools at 248 New Burg St. in Granville, Ohio. Pre-registration is required. Cost for the pre-conference is $45 for members and $55 for non-members and includes lunch.
Space is still available for the pre-conference events. Weekend and Saturday-only conference registration is full. Sunday only registration is still open (but expected to fill up soon) and costs $80 for OEFFA members and $115 for non-members. All Saturday and Sunday meals are currently sold out.

Sweden's reindeer have a problem. In winter, they feed on lichens buried beneath the snow. But the climate crisis is making this difficult. Warmer temperatures mean moisture sometimes falls as rain instead of snow. When the air refreezes, a layer of ice forms between the reindeer and their meal, forcing them to wander further in search of ideal conditions. And sometimes, this means crossing busy roads.

A chance discovery of a beautifully preserved fossil in the desert landscape of Morocco has solved one of the great mysteries of biology and paleontology: how starfish evolved their arms.
The Pompeii of palaeontology. Aaron Hunter, Author provided<h2></h2><p>Although starfish might appear very robust animals, they are typically made up of lots of hard parts attached by ligaments and soft tissue which, upon death, quickly degrade. This means we rely on places like the Fezouata formations to provide snapshots of their evolution.</p><p>The starfish fossil record is patchy, especially at the critical time when many of these animal groups first appeared. Sorting out how each of the various types of ancient starfish relate to each other is like putting a puzzle together when many of the parts are missing.</p><h2>The Oldest Starfish</h2><p><em><a href="https://www.biorxiv.org/content/10.1101/216101v1.full.pdf" target="_blank" rel="noopener noreferrer">Cantabrigiaster</a></em> is the most primitive starfish-like animal to be discovered in the fossil record. It was discovered in 2003, but it has taken over 17 years to work out its true significance.</p><p>What makes <em>Cantabrigiaster</em> unique is that it lacks almost all the characteristics we find in brittle stars and starfish.</p><p>Starfish and brittle stars belong to the family Asterozoa. Their ancestors, the Somasteroids were especially fragile - before <em>Cantabrigiaster</em> we only had a handful of specimens. The celebrated Moroccan paleontologist Mohamed <a href="https://doi.org/10.1016/j.palaeo.2016.06.041" target="_blank" rel="noopener noreferrer">Ben Moula</a> and his local team was instrumental in discovering <a href="https://www.sciencedirect.com/science/article/abs/pii/S0031018216302334?via%3Dihub" target="_blank" rel="noopener noreferrer">these amazing fossils</a> near the town of Zagora, in Morocco.</p><h2>The Breakthrough</h2><p>Our breakthrough moment came when I compared the arms of <em>Cantabrigiaster</em> with those of modern sea lilles, filter feeders with long feathery arms that tend to be attached to the sea floor by a stem or stalk.</p><p>The striking similarity between these modern filter feeders and the ancient starfish led our team from the University of Cambridge and Harvard University to create a new analysis. We applied a biological model to the features of all the current early Asterozoa fossils in existence, along with a sample of their closest relatives.</p>
Cantabrigiaster is the most primitive starfish-like animal to be discovered in the fossil record. Aaron Hunter, Author provided<p>Our results demonstrate <em>Cantabrigiaster</em> is the most primitive of all the Asterozoa, and most likely evolved from ancient animals called crinoids that lived 250 million years before dinosaurs. The five arms of starfish are a relic left over from these ancestors. In the case of <em>Cantabrigiaster</em>, and its starfish descendants, it evolved by flipping upside-down so its arms are face down on the sediment to feed.</p><p>Although we sampled a relatively small numbers of those ancestors, one of the unexpected outcomes was it provided an idea of how they could be related to each other. Paleontologists studying echinoderms are often lost in detail as all the different groups are so radically different from each other, so it is hard to tell which evolved first.</p>
