Biodynamics & Earth Evolution / Autumn Tasks for Farm & Garden

Mac Mead introduces biodynamics in the context of the spiritual-scientific understanding of earth evolution. In the garden, we do hands-on work with the horn manure preparation, and practice making raised beds and planting cover crops.

Introducing the Biodynamic Preparations

Megan Durney

The biodynamic preparations harness life-regulating processes and subtle catalysts to help create conditions for healthy growth. In this class, Mac Mead and Megan Durney lead us in making most of the preparations, and discuss their healing effects on soil and plants.

Soil Building & Composting / Seed Saving Basics

Biodynamic composting practices bring vitality to the soil. In the classroom, Mac Mead explores the relationship of soil science and spiritual science. In the garden, we handle composts of different materials and maturities, build compost piles, make potting soil mix, and treat compost piles with the biodynamic preps. Megan Durney presents hands-on seed saving basics, vital knowledge for the future of our food supply and the health of our farms and communities.

Large Animals & the Farm Organism

The ideal biodynamic farm is a self-contained individuality to which cows contribute milk, meat, and soil fertility. Steffen Schneider, who has been a biodynamic dairyman for more than thirty years, shares his wisdom about dairy herd management, including rotational grazing and pasture management. The day includes a visit to Rockland County’s only dairy cows at neighboring Duryea Farm.

Hugh Williams

Saturday, February 23, 2019
The Individualized Farmscape / Pruning Fruit Trees

Hugh Williams, one of the best orchardists in the East and a biodynamic farmer for over thirty years, brings his perspective on harnessing the local ecology to cultivate the farm individuality. Also covered: the science and art of pruning fruit trees, including a few hours of pruning the Pfeiffer Center’s orchard under Hugh’s expert guidance.

Life Rhythms / Seeing Nature Whole

Sherry Wildfeuer, long-time editor of the Stella Natura planting calendar, explains how the calendar is created, what it tells us, and how we can use it to learn to work with, rather than against, nature’s rhythms and forces. In the afternoon, Craig Holdrege explores how to work with the living dynamic qualities of plants and animals to better understand the world around us.

Water: H2O or Much More?

Water is crucial to biodynamics: Not only to water plants, but for the process of stirring, which potentizes the preparations. But do we really know what water is, what tasks it has in life processes, or how it carries them out? Jennifer Greene of the Water Research Institute takes us far beyond what we commonly know, or suppose we know, of this element.

Jairo Gonzalez

Barrel Compost / Weed & Pest Control Preparations / Small Animals

Barrel compost is an efficient way to boost soil fertility, especially when access to cow manure is limited. In the garden, Jairo Gonzalez leads the class through every step of making this valuable substance, and how to use it. Mac Mead covers weed and pest control using biodynamic preparations, and discusses small animal husbandry (primarily chickens and sheep). An afternoon artistic activity rounds out the day.

Bill Day

Sunday, April 7, 2019
Cosmic Forces in Relation to Nutritional Qualities / Greenhouse Culture & Methods / Bees

By learning how to strengthen and harmonize the influence of the moon and planets on plant life, we can enhance the nutritional value of our food. Presented by Mac Mead. Megan Durney shares greenhouse seeding methods and supportive cultural practices in the Pfeiffer Center greenhouse. In the afternoon, Pfeiffer Center beekeeper Bill Day outlines the biodynamic approach to beekeeping and leads a visit to the Pfeiffer Center’s hives.

The Horn Silica Preparation / Biodynamic Tree Paste / Artistic Activity

The horn silica preparation influences the color, flavor, and keeping quality of produce; Mac Mead leads the class in making this prep in the garden. We also make biodynamic tree paste and apply it to the Pfeiffer Center’s fruit trees. The day concludes with an afternoon artistic activity.

Sunday, May 5, 2019
More Work with Preparations / Prep Storage / Draft Horses

The day begins with stirring and spraying the horn silica preparation, then digging up the preparations that we made back in October. In the afternoon we cover horsepower on the farm, with a visit to the Pfeiffer Center’s team of Haflinger draft horses, and the fine points of prep storage.

Saturday & Sunday, June 1 & 2, 2019
Bringing It All Together

In this final weekend we tie together the year’s material to draw a comprehensive picture of biodynamic theory and practice. We review — by doing — how to make and use all eight biodynamic preparations plus the insect “pepper.” In the classroom, Mac Mead wraps up the year with talks on record keeping, field care and crop rotation, elemental beings, the farm individuality, and the biodynamic cycle of the year. Time is also given to project presentations, artistic activities, and a festive potluck dinner on Saturday night.

Dates and presenters subject to change.
