Healthy soil is key to successful farming and gardening.

Healthy soil is key to successful farming and gardening.

The United Nations declared 2015 International Year of Soils and Shed(25 North St., Healdsburg) celebrates it this week with three events about farming, food and film.

Tonight, there is a free talk about no-till agriculture by Paul Kaiser of Singing Frog Farms. No-till farming is increasingly popular, including in Sonoma County, as farmers reach back to one of the oldest practices of agriculture, a method that is thought to be the way to keep soils as healthy as we possibly can. That talk takes place from 5:30 to 7:30 p.m. and admission is free. If you’d like to go, let them know at by sending an RSVP.

On Saturday, Jim Barausky of Quivira Vineyards, explores his poetic approach to farming with a talk about Biodynamics. Barausky is a former president of the Biodynamic Association and has forty years experience working the land using its principles.The talk takes place from 10:30 a.m. to noon; admission is $15.

On Sunday, Shed continues its ongoing conversation about food with the “Food and Farm Film Fest,” a screening of more than a dozen film shorts, including Real Food Media Contest Finalist Verrückt: The Snail Farmers of Vienna; Fungiphilia Rising and The Goat. Things get started at 7 p.m., cost is $10 and you can get your tickets here.
